Overview

Built for the 718 GT4RS Clubsport: maximum performance and an exhaust note that finally matches that stirring intake sound. This is the header package you've been waiting for.

The GT4RS engine is very sensitive to exhaust length. We invested serious development time tuning primary and secondary lengths so the system sounds great and delivers the performance you expect from Dundon. The result: +20 hp and +33 ft-lb of torque at the wheels.

Constructed from 321 stainless steel for perfect fitment and long-term durability under race conditions.

Want the full system? Pair these headers with our GT4RS muffler for even more performance and sound, or see the Clubsport D3 Power Package for the complete intake and exhaust upgrade.
