The AWE Tuning Porsche 991 Turbo and Turbo S Performance Exhaust System Product Suite
The AWE Tuning 991 Turbo and Turbo S Performance Exhaust System is available in two varieties, with three tip options.
Option One: 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 the following tip configurations:
RSR Style Tips: This tip option provides the most power, as it carries the 3 tubing straight through to the end. Producing an impressive 9hp over the Quad Tips. Available in AWE Tuning Diamond Black finish, or Chrome Silver. Tested and proven under extreme conditions.
Quad Outlet Tips: Available in AWE Tuning Diamond Black, or Chrome Silver finish.
Retaining stock tips: Not ready for the tips? Not a problem. The AWE Tuning Porsche 991 Turbo and Turbo S Performance Exhaust System is compatible with factory tips, for those who want to keep the aesthetics under wraps. You can always add tips later by contacting us here.
Option Two: With test pipe sections
The most aggressive sound available for the Porsche 991 Turbo/Turbo S comes with subbing in our 991 Turbo/Turbo S Test Pipes in place of the High Flow Catalysts. By removing the catalysts and replacing them with 3 tubing, the 991s most primal tones come to the surface. In other words, this is a loud system. Warning: This version will set a check engine light, does not have the AWE Tuning Check Engine Light Guarantee, will wake your neighbors, and is not returnable due to sound preference.
Also available with your choice of RSR Style Tips, Quad Outlet Tips, or you can retain the stock tips.
Please note that due to the use of high flow catalytic converters, or removal of the catalytic converters, this exhaust is legal only for off road use.
