Born from our 997 GT2 tuning program, our Generation 2 997TT muffler saves even more weight over the previous generation.

Utilizing 14 and 16 gauge 304 Stainless Steel and German made HJS 200 cell metal core catalysts, our muffler has been dyno proven to deliver a huge 24 crank horsepower and 30 crank torque improvement over stock in both normal and overboost modes. Meanwhile, our power improvements have come with no sacrifice to sound quality.

Even though our muffler design is a straight through configuration, our use of the most advanced sound packing materials and sound balancing within the single can eliminates drone when at cruising speeds. The sound at full throttle is pure, clean, and muscular.

System Highlights:

• High flow HJS 200 cell metal cats

As with all AWE Tuning ® exhaust products, each TIG weld is hand finished internally, only butt-welded junctions are used, and flange openings are size matched to their ports, all to produce the smoothest flow possible. It is this intensive attention to detail that sets AWE Tuning ® exhaust products heads and shoulders above the rest.

Please note that due to the use of high flow catalytic converters, this exhaust is legal only for racing vehicles which may never be used upon a highway.
