Fabspeed's equal-length 997 Sport headers provide improved torque and equalized engine pulsing thanks to CNC mandrel-bent primary tubes.
INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
Just installed the 997 headers on my C4S. Everything fit perfectly and the look is the typical Fabspeed quality. It's always a shame to bury the beauty of the product beneath the car. Thanks for the best quality exhaust products on the market!
