The AWE Tuning Porsche 991 Turbo and Turbo S Performance Exhaust System Product Suite

With high flow cat sections

Producing an exhaust system that is both aggressive at full throttle yet civil enough for Bluetooth calls is no small endeavor. Using the AWE Tuning 200 Cell HJS HD High Flow Cat Sections, AWE Tuning sound engineers carefully studied the tones of the multiple prototype 991TT systems at various RPMs, and meticulously engineered a bespoke 991TT solution (as opposed to a repurposed 997.2TT system) to combat frequencies that are not appropriate for a supercar of this caliber "" retaining and building upon only the perfect notes. All while producing an impressive 29+ horsepower at the crank along with the AWE Tuning No CEL Guarantee.

Using 3.0" diameter T304 Stainless Steel tubing and an H-Pipe design, the AWE Tuning muffler section routes exhaust gases through two proprietary and hand-crafted mufflers to create the AWE Tuning signature sound.

This system is available with:

Quad Outlet Tips: Available in AWE Tuning Diamond Black finish.
