Dundon Motorsports Race Headers - 991 GT3/RS
Constructed from 321SS tuned length stepped headers and flapped side connector, the exhaust combination offers a 40whp increase for GT3 owners and 25whp for GT3RS owners with no ecu flash required. By understanding exhaust flow and resonance tuning, Charles Dundon developed this combination. The use of the the OEM center muffler and flaps allow for drone free, quiet cruising and a glorious porsche roar when on the throttle! This setup is bolt on and can be selected with or without the exhaust flaps.
