SOUND:
The Supersport X-Pipe Exhaust System will bring out a deeper, throatier tone from your 991 Carrera's flat six with a substantial increase in volume.
POWER:
Our final design of the Supersport X-Pipe saw an increase of 13 whp and 11 ft/lbs of tq at 6400 RPM and an impressive 27 whp and 37 ft/lbs of tq at 3800 RPM. You'll feel the increase in power and throttle response throughout the RPM band.
