Why You Need a Performance Exhaust
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).

A High Performance Exhaust System – The Key to More Power and Better Gas Mileage
A high performance exhaust system is one of the easiest and most cost effective modifications you can make to your car. Not only is a high performance exhaust system very effective and affordable, it is also fairy easy to install. These days, due to the rising cost of gas, the subject of gas mileage is on just about every driver’s mind. A high performance exhaust system will help increase mileage too.
If it seems too good to be true that a single modification such as an exhaust system would give so many benefits, it is most definitely not. Even better is that so many of the benefits of a well designed performance exhaust system, such as better performance and gas mileage, are usually mutually exclusive. Not the case here, though. Why are so many advantages to be had by simply installing an exhaust system?
It all comes down to the compromises made by the auto manufacturers. They have to balance many things when designing a vehicle; cost, weight, noise, performance, gas mileage, and a myriad of other things such as supplier relationships. In short, they can’t give you the best exhaust system available because it would raise the price of the vehicle too much. In addition, they have to abide by EPA noise restrictions and build a vehicle for the broadest number of car buyers. That alone requires compromise. The car, or any of its parts, simply can’t be perfect in every respect, for every car buyer.
Once it’s your car, on the other hand, you’re free to make any improvements you see fit. If a nice, low rumble doesn’t bother you, a performance exhaust could be just the answer you’re looking for. Like may performance enhancing modifications, the quality of available systems run the gamut from truly pathetic to finely engineered works of automotive art. Where on the spectrum you want to be is determined by your requirements and budget.
Keep in mind that to properly design exhaust system requires specialized knowledge, equipment and experience. If the system is improperly designed, chances are it will make more noise, but no more power or gas mileage. In fact, due to the high level of factory engineered systems these days, you may even hurt your cars’ performance with a poorly designed exhaust.
Because they are relatively inexpensive, offer decent performance gains, and is easy to install, most people opt for a system that comprises only the system from the rear of the catalytic converter to the exhaust tip. This is known as a “cat back” system. More performance can be had by installing a complete system from the exhaust manifold to the tip, however. You can even install a high performance catalytic converter to maximize performance and fuel economy.
There are some features you should look for when selecting an aftermarket exhaust system. The first is the type of material it’s made of. Any of the better systems will be either coated steel or stainless steel. The standard stainless steel alloy for a high quality exhaust system is T-304, steel alloyed with about 10% nickel and 20% chromium for strength and corrosion resistance.
You may also find exhaust components made from T-409 stainless. While this is a good material, it doesn’t have the strength or corrosion resistance of T-304, so it will exhibit discoloration over time and won’t last as long as a system fabricated from T-304. T-304 is harder to work with and more expensive to procure, so be prepared to pay a premium to buy a system made from it. As with many things in life, if you want high quality, be aware it costs more.
If you are after the finest quality exhaust system, you may find it’s made from T-316L stainless. This has even lower carbon content than T-304, and is used extensively in marine exhaust products, due to its superior corrosion resistance. The absolute best stainless steel material for an exhaust system is T-321 stainless, steel alloyed with the wonder metal titanium. As you might expect, T-321 is extremely expensive, and fairly rare in street exhaust systems, although common in race units, such as IRL and F-1. You’ll also find T-321 used in aircraft construction, where the margin for error is small indeed. If you’re after a price no object exhaust system, you can have one custom fabricated from Inconel 625, a nickel alloy used in construction of the X-15 rocket research plane. No, unless you’re driving a Ferrari, you probably can’t afford it.
Another advantage of stainless steel as an exhaust material is that it conducts heat less readily than does mild steel. This serves as a thermal barrier, keeping exhaust heat inside the exhaust tubes. If you are investing in headers or exhaust manifolds made form stainless, the benefit of the lower thermal conductivity will be better exhaust velocity. The higher velocity will give better scavenging, so you’ll get more complete exhaust flow out of your cylinders. This means more efficient engine operation, increased power and better gas mileage.
If you’re not prepared to pony up for a stainless exhaust system, you can find fine products made from varieties of coated steel, such as aluminized steel or ceramic coated steel. These have some of the properties of stainless, such as corrosion resistance, or, in the case of ceramic coated products, low thermal conductivity.
The next thing to look for in a high performance exhaust is mandrel bending. Mandrel bending ensures the tubes are bent without reducing the diameter, and thus adding restriction. This restriction will hurt exhaust flow, power and efficiency. With mandrel bending, there is actually a piece of tooling (the mandrel) placed inside the tube as it is being bent to prevent the exhaust tube from being reduced in interior diameter. While the best method of forming bends in exhaust tubing, it is quite expensive, and most low priced systems don’t use this method. The performance of the finished system will suffer, however. Some estimates are that for a system with 5 bends, mandrel bending reduces exhaust backpressure by about 30%.
A new high performance exhaust system is one of the fastest, most cost effective performance enhancements you can make to your vehicle. In addition, you’ll reduce weight, save gas, increase longevity, make it look better, and oh, that sound!
