AWE Tuning Performance Cat-Back Exhaust System - Porsche 911 Turbo, Turbo S 991.1 2014-2016

AWE Tuning 3015-42040


Exhaust 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 handcrafted mufflers to create the AWE Tuning signature sound.


Due to the use of high flow catalytic converters this exhaust is legal for racing use only.
