AWE Tuning xhausts 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 crusing at part throttle, while also producing a war-cry wail when full throttle is applied. Sophisticated, refined, and powerful, all at once.

For cars with that came equipped from the factory with dual tip rear mufflers only at this time. Some models with hidden factory tips will need to cut the rear valence and install the late model lower bumper trim to use this system.

AWE Tuning engineers spent considerable time examining how to maximize the performance and options of this exhaust system. The AWE Tuning ® exhaust boasts features ensuring unmatched power, fitment, and sound levels. And awesome appearance, too!

Each system is mandrel bent 2.50" T304 stainless steel, and is a full catalytic converter back design, producing gains of 10-15hp crank horsepower. Our straight through resonator and muffler design ensures flow while keeping the noise level down to civilized volume. There is no drone with this system!

The rear muffler is a single 2.5" inlet, dual 2.25" outlet design, with full T304 stainless steel construction including the packing material. Our signature 3.15" beveled exhaust tips sport laser etched AWE Tuning logos and are double walled to ensure a mirror polish even under hard usage. These are the best looking tips on the market.

The prototyping process was a long road: AWE Tuning sound engineers carefully studied the tones of prototype exhaust iterations at various RPMs, ultimately engineering a solution that combats frequencies that are not appropriate for a car of this caliber – retaining and building upon only the perfect notes.

You won’t get a check engine light. We guarantee it. By ensuring that factory O2 sensors stay in locations that keep the Porsche ECU within factory specifications, we ensure that you won’t see the light.
