SOUND:
With PSE (Porsche Sport Exhaust) on and the valves open, this system turns the 4.0L's exhaust note into a truly exotic sound GT4RS sound with a significant increase in volume utilizing our iconic and highly sought after GT4RS X-pipe. This system will turn heads as you rip by, some cheers from the nearby pedestrians may have you hitting the accelerator a little more often. Tolerable enough for street driving and highway cruising, and intoxicating when driving with a bit more spirit.
POWER:
After many dyno hours and incremental refinements to our design we were able to achieve dyno gains of 25 WHP and 19 FT/LBS of TQ at 7500 RPM. Best of all, power gains are seen as low as 3700 RPM, so there are power gains across the entire power band!
