Presenting the only Porsche 991 Turbo and Turbo S Exhaust System with enough craftsmanship to bear the AWE Tuning name. Behind the finished product are hundreds of hours of prototyping, engineering, research, testing and daily usage evaluation; outputting an exhaust system that is equal parts sophisticated and aggressive.


Highlights


• Peak Gains: + 29 hp / + 32 ft lb at the crank with RSR Style Tips
• Peak Gains: + 20 hp / + 20 ft lb at the crank with OE tips or Quad Tips
• Bespoke 991TT system, not a repurposed 997.2TT system
• German-made 200 cell HJS HD metal-core catalysts
• No CEL. Guaranteed.
• 3.0" mandrel-bent tubing with H-Pipe crossover for optimal acoustic performance
• T-304 Stainless Steel Tubing
• Direct bolt-on
• Included gaskets & hardware
• Engineered, designed and manufactured in house at AWE Tuning







Three 991 Turbo / Turbo S options from which to choose:


RSR Style Tips: This tip option provides the most power, as it carries the 3” tubing straight through to the end. Available in AWE Tuning Diamond Black or Chrome Silver finish. Tested and proven under extreme conditions.


Quad Outlet Tips: Also 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.














Power to the Porsche


We saw Peak Gains of + 29 hp / + 32 ft lb at the crank with RSR Style Tips, and Peak Gains of + 20 hp / + 20 ft lb at the crank with OE tips or Quad Tips.








One system. Many talents.


Producing an exhaust system that is both aggressive at full throttle yet civil for Bluetooth calls is no small endeavor. 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.


Premium German made 200 cell HJS HD metal core catalysts guarantee Check Engine Light free operation, 3.0" diameter tubing and the AWE Tuning muffler design routes exhaust through two proprietary and hand-crafted mufflers, while an H-Pipe design helps ensure the perfect note. Each TIG weld is hand finished internally, and gas purge welded. Flange openings are size matched to their ports, all to produce the smoothest flow possible.


The result is an exhaust system that unlocks the 3.8L Twin Turbo powerplant in both performance and sound, in a way that no other can. More details, including pricing, can be found on the AWE Tuning 991 Turbo and Turbo S Performance Exhaust Webpage.
