The new TT is a great package right off the showroom floor, but begs for an exhaust note that matches its personality. That is why we developed our Mk2 TT Turboback Exhaust system.

Our exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. We spend considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. Our exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.

We spent considerable time examining how to maximize the performance and options of this exhaust system. The factory exhaust consists of a long downpipe with two catalytic converters, and two rather large mufflers in the section after the cats.

Thorough long term street testing has confirmed that our high flow downpipe, whether equipped with with the 400 cell ceramic catalytic converter or the 200 cell metal catalytic converter, will not set a Check Engine light or any fault codes in the ECU. For customers looking for ultimate power, our HJS German made metal catalytic converter featuring an Emitec core will provide an additional 9hp over our ceramic converter option.

Here are some features of our system. Each feature was chosen for performance and longevity reasons, and when making your exhaust decisions you should settle for nothing less:

The downpipe features an integrated resonator to keep the exhaust sound volume civilized even with the elimination of the very restrictive factory converters. Our downpipe is the first performance downpipe to be released that will not throw a Check Engine Light one the latest CBFA engine code TSI 2.0T cars.

The catback system is topped off with our signature 3.15" beveled exhaust tips available in a classic Polished Silver or a Limited Edition Diamond Black Finish. The tips sport stamped AWE Tuning logos and are double walled to ensure a mirror polish even under hard usage. The system has multiple slip joints with high quality stainless clamps, to allow optimal adjustment.

Our catback systems will mate up to the stock downpipe, and our downpipe will mate to our catbacks or any other catback that is designed to mate up to the factory downpipe.

Why did we choose 2.5 inch and not 3.0 inch diameter for our TT exhaust? The first prototypes of our 2.0T FSI/TSI systems were indeed 3.0 inch, but we found that the effort it took to move the large mass of air in the 3.0 inch system at lower rpms resulted in a loss of torque with very little offsetting gain up top. Take a look at our 3.0 inch prototype dyno sheets here and see why a 3.0 inch system is not appropriate for this car.

Please note that due to the use of high flow catalytic converters, our downpipe section is legal only for racing vehicles which may never be used upon a highway.
