AWE Tuning exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. AWE Tuning spend considerable time and effort during development to achieve remarkable civility when idling and cursing at part throttle, while also producing a war-cry wail when full throttle is applied. Sophisticated, refined, and powerful, all at once.
AWE Tuning spent considerable time examining how to maximize the performance and options of their 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.
The catback system is topped off with our signature 3" beveled exhaust tips. 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 band clamps, to allow optimal adjustment.
AWE Tuning catback systems will mate up to the stock downpipe, and AWE downpipe will mate to our catback 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 MK5 exhaust? Our first prototypes of this system 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 AWE 3.0 inch prototype dyno sheets here and see why a 3.0 inch system is not appropriate for this car.
