Many people think that the Mazda exhaust system is basically the car’s muffler. The truth, however, is that, the system is basically made up of a series of pipes underneath the body of the car that is connected to the muffler and the catalytic converter. The main function of the exhaust system is to keep noise levels to a bearable degree to as well as to route exhaust fumes away from the passenger cabin.

The Mazda exhaust system disposes of waste gases produced by the engine by letting them pass to the rear of the car, finally departing through the muffler. These exhaust fumes are discharged into the atmosphere since such substances contain noxious pollutants, mostly carbon monoxide. Carbon monoxide impairs the ability of the blood to absorb oxygen into the lungs, leading to serious health problems. Inhaling huge amounts of this gas can thus lead to poisoning. Carbon monoxide poisoning, in turn, can inflict a series of ills on a person. Headaches, fatigue, flu-like symptoms, as well as potential heart problems, are simply a few of these ills. In addition, chest pains, irregular heart beats, and in some cases, cardiac arrest are also common results if one is subjected to high intakes of carbon monoxide. In addition, the Mazda exhaust assembly also converts pollutants into less harmful by-products, levels down the noise of the engine, as well as directs exhaust gases so they can be utilized to heat air and fuel before they are burned in the engine’s cylinders. Another function of the exhaust system also includes the production of backpressure into the engine at just the right amount so as to improve the engine’s fuel-burning efficiency and performance.

The components of the Mazda exhaust system generally include the exhaust pipes. These are designed specifically for each car model so exhaust fumes are certain to be routed properly to whichever direction they need to go. Then, there’s the exhaust manifold. This component serves like a funnel; that is, it collects exhaust gases from all cylinders. After which, it releases them by way of a single opening. While the catalytic converter is well designed to lower the resulting harmful emission products generated by the engine. The system accomplishes this feat by transmuting pollutants into water vapor and other harmful gases that are significantly less harmful. Rounding up the exhaust assembly parts is the muffler. This is basically a metal container with chambers, baffles and holes. The resonator which works with the muffler to cut back exhaust noise and the tail pipe designed to direct exhaust gases away from the vehicle, are also included. As for common system troubles, rocks, dirt, and mud contribute a great deal in the failure of the Mazda exhaust system. If one notices that the engine seems to be running on less power, or if foul odors or odd noises are coming from the muffler or any portion of the exhaust pipes, then it’s already best to have the Mazda exhaust system checked and if already beyond repair, replaced by a professional.

When comparing high performance vs. standard replacement parts, it is of extreme importance to weigh performance and durability against value and cost. Long term costs of replacing OEM items with low-priced “budget” items or after-market replacement parts can, in many cases lead to higher consumer long-term costs. It can also lead to irreversible damage to primary and connected related systems. Obviously, if a replacement part is of lower quality and of shorter durability, it will need to be replaced more often. There are costs associated with the labor to replace these parts more often, as well as time lost for actually doing the work of replacing an automotive component. There are other “hidden” costs as well associated with this practice. They may not be costs in cold, hard cash out of pocket, but they are costly, nonetheless.

A good example of this is simply shopping around for spark plug wires for my old Buick. I got in the habit of replacing the wires at least once a year, sometimes more if a problem arose. I go to the Internet and find several varieties of options online and I read the descriptions of what my choices are. They look like this:

Description: Taylor Cable 69.95

8mm Street, Ignition Wire Set, Custom Fit, SST, Blue, Tin Coated Copper Braid, Non RFI, Blue Double Spring Locking Spark Plug Boots, High Temperature Rated To 550 Degrees, Competition Looks, GROUND SHIPPING ONLY

Description: OEM 37.41

Premium Wire Set, Spark Plug Wire Set, OEM Fit And Quality 37.41

Description: Taylor Cable 29.95

8mm High Energy, Ignition Wire Set, Custom Fit, Blue, High Temperature, Oil Resistant, RFI Suppression, 100% Silicone Boot Ends, Double Spring Locks At Plugs, GROUND SHIPPING ONLY

The first thing I notice is the huge difference in price, and like any good spendthrift, I am drawn to the cheapest spark plug wires available. Ignoring the statements about temperature ratings and RFI, I immediately think to myself, without any further research, I may want to buy the bargain set of wires. But then I think I want good wires, and the OEM brand is only eight dollars more. These are the spark plug wires that came with my vehicle, so they must be what I need. I buy them online for $37.41, have them shipped to my house and install them on my vehicle.

I take my old car for a ride, to see how much better it is going to run with the new wires on it. I notice it doesn’t run any better, as a matter of fact, it now has a slight miss in the engine. So I turn off the engine, get out of the vehicle and make sure everything is connected properly. The miss isn’t there anymore when I start the vehicle back up, so I am happy. I turn the radio on to listen to some tunes on the way back to the house, and I can hear the sound of my engine “running” on the radio, like a whining sound, drowning out a portion of the music.

I get back to the house and look at the old wires I took off in favor of the new “original equipment” wires. They don’t look the same. The old ones look heavier and bigger. The next day, I start the car up and the “miss” is back, and the engine “whine” is still on the radio. Frustrated, I put the old wires back on the car and the problems go away. So I go back to my computer and look at custom and high performance plug wires for my old Buick, and here’s what I see:

Spark Plug Wires

Brand: Taylor Cable $108.95

8mm Street, Ignition Wire Set, Custom Fit, Full Metal Jacket, Black, RFI Suppression, Braided Stainless Covering To Polished Aluminum Covers Over Silicone Plug Boots, High Performance, Custom Appearance

Spark Plug Wires

Custom Fit 300 Race, Stainless Spark Plug Terminals, Complete EMI/RFI Suppression, 600F Temperature Resistance, More Spark Energy, More Power, Spark Plug Wire Set, 8.8mm, Wires Routed Over Valve Cover, Black

This time, I do a little research to find out what I do not understand about the sales descriptions offered. Here is what I find out about the difference in spark plug wires:

OEM wires generally rely on carbon conduction and are also used in the majority of stock replacement wires. This form of ignition wire is cheap to manufacture and generally provides adequate initial suppression for both RFI (radio frequency interference) and EMI (electromagnetic interference). The conduction portion is generally made of fiberglass or kevlar over which resistance conductive latex or sometimes silicone is layered over top. This reduces spark current to provide suppression. This works well while the conductor lasts, but it has a limited life. This type of conductor quickly fails if a high-powered ignition system is used. Temperature resistance is generally in the 550 degree F range.

I also find out that EMI from OEM spark plug wires can cause incorrect signals to be sent to engine management systems and on-board electronic devices. This is why suppression is so important. It works the same way that RFI can cause unwanted signals to be heard on my radio receiver. Engine running problems like intermittent misses to a major loss in power loss can be the result. I also find out that the problem can get worse with age due to corrosion of the sensors and connectors. Also, high performance wires can protect in temperatures as high as 1000 degrees F.

I went back to my Buick and looked at the ignition system. It had not been replaced by a high-powered ignition system. I ordered the Taylor custom 8.8-mm wires with RFI suppression for $25.57.

$11.84 less than I paid for the OEM ignition wires. I installed them a few days later when they arrived and have had no problems at all. In fact, my gas mileage has increased and my responsive acceleration increased. I have had them on my Buick for two years now and they still perform as well as the day I put them on.

Replacing with high performance automotive parts are generally considered upgrades and higher costs are associated with better quality and higher performance. As this exercise taught me, this is not always the case. Higher performance means value-added in the long-term. This relates to better customer satisfaction, better performance and durability, sometimes even less expense, but always a better value and a lot less hassle.

The exhaust system is integral in any Honda vehicle. It is basically a group of pipes and tubing designed to direct the exhaust gases created by the engine to the atmosphere. It consists of many components that help in this operation. One of these is the Honda muffler. Also called silencers, Honda mufflers reduce the exhaust noise for the comfort of the passengers. They also eliminate some of the toxic elements in the exhaust gases before these are released in the atmosphere.

Inside the muffler, a set of tubes capable of creating reflected waves can be found. These waves basically cancel each other out as the exhaust gases and the sound waves come in the center tube. They are then spring back to the muffler to go through different holes into another chamber. This is where the gas and noise come to the last pipe, and released to the atmosphere. Through the help of a resonating chamber, Honda mufflers can minimize the exhaust noise. Linked to the first chamber through a hole, the resonator holds a required volume of air and length that create a wave to decrease the sound. The resonator can commonly be found under the rear of the vehicle. In trucks with diesel engines and large mufflers, however, the resonator is located behind the cab.

Honda mufflers also contribute to the vehicle?s performance while reducing backpressure. Since the late 20th century when mufflers of this type were invented, they have been proven to improve the efficiency, performance, and power of the engine. They also extend the life of engine components. Another type of muffler capable of diminishing backpressure is a glass pack or a cherry bomb.

To maintain the performance of your Honda at a maximum level, you need efficient Honda mufflers. Our site offers a wide variety of mufflers guaranteed to give your vehicle a powerful performance and a smooth exhaust operation.

There are some opinion about end point of automotive lubricant for gasoline engine and gasoil engin.
for example
about gasoline automotive performancey someone says :
-when TAN arrive to TBN or
-25% change versus the new oil viscosity ( viscosity @40deg.C)
-15% change versus the new oil viscosity ( viscosity @100deg.C)
– Insolubles 0.5% or more
What ’s your opinion if you are an expert about lubricant oil ?
Thank you very much.

To ensure car manufacturers meet the expectations of the mainstream customer, many of today’s cars leave the factory with low-velocity, ultra-quiet exhaust systems. As a result, exhaust flow (along with power and torque) is restricted. But our performance exhaust systems release this stranglehold on your engine. By using patented technology to boost exhaust flow velocity, our exhausts systems unleash the power and optimize your cars performance.

What’s more, you will gain a non-raspy distinctive euro exhaust note. And while stock exhaust systems tend to discolor and lose their showroom appearance quickly, our systems ads fine motorsport styling to your vehicle, designed to endure years of heavy use. Precision manufacturing using aircraft quality T-304 stainless steel prevents corrosion, and keeps your exhaust system looking new. Each system includes a variety of trademark engineering enhancements. Including ultra-smooth mandrel bends for maximum flow and power.

Sport Exhaust Systems:

If you are interested in modifying you VW/Audi for better performance, the exhaust system should be the first step. A good sport exhaust will provide more power for the money than any other modification you can consider. Plus, a sport exhaust makes your car sound that much better. Usually, both horsepower and mileage go up when you upgrade the exhaust.

Note: Failure to change the exhaust before making other performance modifications can hurt performance. Some cam and chip upgrades just do not work properly without upgrading the exhaust system.

The cast iron dual outlet manifold lasts and lasts and is quieter than a tubular header. In most cases, your stock cast iron exhaust manifold or a cast euro-manifold will offer excellent results when used with a Techtonics Tuned downpipe or euro-downpipe and sport exhaust system. (The exceptions to this are the ‘82 & up Scirocco, ‘83-’84 GTI/GLI single outlet manifolds.) The difference in power output between the best headers and the stock or euro-manifold/Techtonics Tuned downpipe combination is quite small.

Techtonics Tuning has a downpipe for use on the early VW’s with stock catalytic converters. A direct replacement on early cars with a stock dual outlet manifold or cars that have been fitted with the dual outlet manifold, this downpipe will “keep you legal” while adding about 8% more horsepower to a stock motor. Something else to consider: Due to the rocking motion of a transverse mounted engine, it is difficult to make a header that will hold up well. Tubular headers just do not last for most people.

BBM is very pleased to offer you Techtonics Tuned Exhaust for the earlier VW’s. This system doesn’t make as much “advertised” horsepower as our competitors claim their’s does. However, in terms of “real” dyno tested power Techtonics Tuning systems have the competition marking their words.

Another plus for the TECHTONICS TUNED exhaust is that all parts for the system are available separately. How do they fit? With more than 20 years of refinement TT systems fit better than the competitions. All systems have a resonator as well as a muffler to dampen out harsh sound levels.

Stainless Steel Exhaust Systems:

Simply the best fitting and longest lasting exhaust system available for your VW. With over 20 years of refinement and upgrading we are able to offer a * Limited Lifetime Warranty on all stainless steel cat back exhaust systems. Our latest systems are made of 304 stainless steel. This includes the tubing, clamps, resonator, and muffler. Perfect for “salt belt” dwellers. Nobody gives you the options that TT offers. You can choose the sound level by ordering the system with 0,1 or 2 resonators (available for the Mk2, Mk3, Passat 16V & Corrado G-60).

The GM exhaust system is one of the most frequently rejected parts of a vehicle. This is because most people tend to focus on body and engine improvement. However, what most people don’t know is that the exhaust system performs a very important role. Vehicles create harmful gases during the combustion of fuel. The GM exhaust system carries harmful exhaust gases away from the passenger compartment and also converts most of the harmful gases into acceptable by-products. Moreover, it helps in reducing the sound made by the internal combustion engine, reduce the temperature of the exhaust and control the emissions that come out of the vehicle.

How does the GM exhaust system work? The GM exhaust system begins with the exhaust manifold on the engine. Hot exhaust gases flow from the manifold through the front or header pipe into a catalytic converter. The converter changes unburned hydrocarbons (fuel) and carbon monoxide into water vapor and less harmful carbon dioxide. Inside the stainless steel case of the converter, there is a ceramic honeycomb coated with a thin layer of platinum. When the exhaust gases pass through the hot converter, they are changed. From the converter, the exhaust flows through another pipe to the muffler. On most cars, the exhaust now flows out the tail pipe, but on some models, the exhaust passes through a secondary muffler called a resonator. Finally, clamps and rubber mounts called hangers support the exhaust system under the vehicle.

Rocks, dirt, and mud affect the performance of the GM exhaust system. If there is less power, foul odors, or odd noises coming from the muffler, it might be time to replace the GM exhaust system.

The GM exhaust tip is one accessory that is designed to enhance a GM vehicle’s appearance and to help in the exhausts systems performance. It adds a bit of style and uniqueness to the tail end of a car and it can also actually affect the volume of the exhaust tone. The larger the GM exhaust tip , the more volume that one will get from it.

GM exhaust tips are available in various types, styles, and sizes. They are either resonated or non-resonated. Non-resonated tips are just plain stainless steel tips. The resonated tips are lined with fiberglass to dampen the exhaust noise a little further. Sizes range from 2 inches to 5 inches wide. Styles to choose from include round, oval, square, slashed, etc. Exhaust tips can either be welded on, or if possible, clamped on.

I’m writing a paper for college and it’s about performance management but I have to link it to my career and I work in the automotive industry. My book discusses Hewlett-Packard for their example so I would like some information other than HP info.

Because most of the engine action happens right at the exhaust system, components like your Pontiac muffler is commonly overlooked for modifications aiming to boost performance. With all that massive pipe and tubing that helps your engine direct harsh and hot emission out of the system and engine compartment, your muffler pipe or pipes could help you take your car?s overall level of performance a level up notch. Typically engineered to cancel out or minimize exhaust noise, the part could actually help manipulate backpressure to yield the desired engine power at specified rpm range. For high performance driving applications, powerful muffler constructions have been employed so your engine roams as a winning piece of mean machine. While muffler manufacturers take leverage in the functional features and distinction of the sound their pipes deliver, time and application tested technologies have been incorporated to let you enjoy powerful engine performance while following the course of your driving style with absolutely no fail. The part is typically installed along the exhaust pipe to serve as the resonating chamber where exhaust noise waves cancel out. As a result, the performance tuned exhausts complete your vehicle?s commanding presence with an assertive tone.

Due to the continuous fuel combustion processes, your engine continuously release harsh exhaust gases which are delivered through their designated routes to undergo a series of combined chemical and mechanical processing. After passing through electronic sensors and the catalytic converter, the fluid is then delivered to the exhaust mufflers prior to its release outside the system. Without mufflers or exhaust sound silencers, the sound created while your engine pushes out hot and harsh exhaust gases will be unbearable. Tough constructions of stainless steel Pontiac mufflers are employed by your car to effectively fine-tune your car?s exhaust sounds. The most important aspect of muffler design will be the amount of backpressure it could produce. While the stock mufflers typically generate high levels of backpressure, it subtracts a significant portion of engine power as your engine runs. To reduce backpressure, sound absorption features to application have been established. Glass insulation at tubing walls have been incorporated for insulation. As a result, pressure pulses are better absorbed. The use of advanced automotive technologies to practical Pontiac muffler applications have significantly improved fuel efficiency, performance and power output while reducing overall engine wear and tear.

With the continuous efforts to muffler construction development research, less restrictive mufflers are now made conveniently available to help you achieve your set car performance goals. To deliver the sound levels in compliance with the law, Pontiac muffler is comprised with less restrictive set of exhaust tubes that facilitates reflection of sound waves. As the reflected sound waves are made to interfere with one another, they practically cancel out resulting to a more bearable exhaust tone. To do that, the part is strategically mounted at points where processed exhaust gases are more efficiently collected. Well-crafted cars like your Pontiac ride is typically designed for quiet exhaust operations. Once you experience increased exhaust noises or increased judder to exhaust pipes, immediately consult a qualified service technician so his accurate diagnostics could immediately correct potential causes of muffler damage or failure.

I am interested in learning High performance Engine Building and Chassis Fabrication. I have only been able to find two which appear to have what I’m looking for.
One is UTI (www.uti.edu) and the other is Wyotech (www.wyotech.edu).
Please suggest if there is another option out there?
Thanking you

The aftermarket motorcycle exhausts are a great way to enhance your motorcycle’s performance in terms of better and more powerful operation. Honda CBR exhausts are now available in a number of styles, each with a different set of features. You can find easy-to-install exhaust systems for almost all CBR models including CBR929RR, CBR954RR, CBR900RR and CBR1000RR. There are basically three types of aftermarket exhaust systems for motorcycles: slip on exhausts, full exhaust systems, and race exhausts. They are made up of high quality materials that resist shocks and fierce weather conditions.

Most motorcycle enthusiasts replace factory-installed exhausts to create an intimidating rumble which is a characteristic sound of heavy bikes. Exhaust systems for motorcycles are made by using titanium, stainless steel, aluminum and carbon fiber. Titanium and aluminum are very light weight metals and they are also very durable. You will notice a considerable change in the way your motorcycle moves after installing these custom exhausts. Some of these systems are composed of duplex crossover tubes attached to the header for an even better performance.

Motorcycle exhaust systems are required to collect waste gases from the combustion engine and release them to the atmosphere. Some systems are designed to be more effective than others because they use more robust parts and wider pipes to allow for a smooth air flow. CBR exhausts come with excellent features like weight saving, race can performance and lifetime warranty. You can also check out down pipes as separate parts to replace the existing stock pipes. OEM, standard and slip-on down pipes are available on the market which are very easy to install and deliver maximum output. In addition to these, you can also check out full exhaust systems which come with cone-shaped end caps. These systems can be bought for $600 to $900 depending on their material and features.
