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).
