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 cruising at part throttle, while also producing a war-cry wail when full throttle is applied. Sophisticated, refined, and powerful, all at once.
We spent considerable time examining how to maximize the performance and options of this exhaust system.
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:
- Fully mandrel bent tubing
- Available with Round tips in Chrome Silver or Diamond Black Finishes
- Thick .065" wall T304 stainless steel tubing
- Stainless steel internal muffler and resonator construction
- Stainless steel MIG and TIG welds
- Stainless steel T-bolt clamps
- Double-walled exhaust tips to reduce heat discoloration
- In-house dyno-developed
The catback system is topped off with your choice of 102mm slash cut tips available in chrome silver or a luscious diamond black finish. The tips sport laser-etched AWE logos and are double-walled to ensure a mirror polish even under hard usage. The system has multiple slip joints with high-quality stainless band clamps, to allow optimal adjustment.
Why did we choose 2.5 inch and not 3.0 inch diameter for our MK6 exhaust?
Our first 2.0T exhaust prototypes 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.

AWE 2.0T Exhaust Dyno Tests
Below are comparison dyno tests as performed on our Mustang MD-500-SE AWD dyno.
All tests were performed on the same car, with controlled ambient conditions. Each test is average of 3 runs performed.
Cat Back Exhaust Testing
Our first prototype for the A3/GTI/GLI was a 3" diameter cat back system. Careful before and after dyno testing showed that for this car, bigger was definitely not better. The air mass found inside the 3" tubing proved to be a restriction to the engine until the higher rpm region, and even at that point gains were minimal. Our reputation is to bring only proven products to market, and a 3" system is definitely not the wise choice for power on this car. Design was rejected.
After further dyno testing, we found that a 2.50" diameter gave the best overall balance of torque and horsepower gains. Peak gain were 3.1whp and 0.1wtq.
In the graphed gains sheet below you'll find the measured differences between baseline and test in dyno sheet of AWE 2.50" Cat Back Dyno Test vs stock exhaust. The AWE 2.50" exhaust produces a maximum increase of 4 wheel hp at 5300 rpms and 28 wheel torque at 2400 rpms vs. the stock exhaust. Overall, gains are seen over practically the entire powerband.
