Overview

Fabspeed 997 GT3 Sport Headers: sport headers that replace the factory exhaust manifolds for better flow and a sharper response, for the 2007-2008 Porsche 997 GT3 / GT3 RS.

Why headers matter

Headers set how well the flat-six breathes. Long, equal-length primaries and smooth merge collectors scavenge exhaust pulses more efficiently than the factory manifolds, which helps power at high RPM.

Installation

Plan for a professional install. The headers bolt in place of the factory manifolds, and the factory gaskets can be reused if they are in good condition. Re-torque the fasteners after the first heat cycle.
