Are you looking to take your Cayman GT4 to it’s maximum performance potential in 2018?

Get out of the corner fast and maximize your pulling power on the straights with our Cayman GT4 Race Headers! Designed for track and off-road use, these catless longtube headers provide maximum exhaust flow from the engine cylinders straight into the exhaust system.



Our precision-engineered race headers are built to optimize the engine’s exhaust flow for maximum performance, adding up to 18 horsepower at the wheels and 15 ft/lbs of torque at 6300 RPM, increasing the already impressive performance of the Porsche GT4. Down low, these Race Headers give you a kick in the pants, adding 27 whp and 38 ft/lbs of torque at 3700 RPM.

Constructed from equal-length T304 Stainless Steel C.N.C. mandrel-bent tubing, our race headers save 10 lbs. from the rear of the vehicle as well as provide improved torque and equalized engine pulsing. These are a direct replacement for the Porsche OEM headers, and installation requires no welding or cutting.
