Perrin Headers

Reaching back to lessons learned by tuners in our past, PERRIN? has grabbed a dramatic power increase that was previously bottled up by the factory manifolds. Whether normally aspirated or turbocharged, proper exhaust gas scavenging is vastly important. The turbocharger relies on energy from the exhaust flow to rotate its blades. By freeing up energy that was otherwise restricted by the factory manifold we can transfer that to the turbo to decrease spool up times and improve power.  Our R&D staff was able to manipulate the length and shape of each runner to allow easy installation and still maintain large power increases.
