The headers on this latest 991 system include a double plated flange. This flange dissipates heat and vibration more efficiently and consequently does not warp like thicker single plate flanges commonly used by others. This small advancement is time consuming to make but is added in order to prevent loss of power over time and will ensure years of trouble free operation even under severe track conditions.



The header piping incorporates a 2 3/4" motorsports style merge collector. The collector smooths out exhaust flow and turbulence created from the 3 primary pipes merging into one. Collectors create more velocity, which reduces back pressure and creates torque. This systems collector gently guides ex...(choose a part on the right to read more)
