FabSpeed Porsche 997 Carrera Sport Headers (2005-2008)

Fabspeed's equal-length 997 Sport headers provide improved torque and equalized engine pulsing thanks to CNC mandrel-bent primary tubes. SOUND: These equal headers really bring out the melodic flat 6 sound. Expect a small increase in volume with no drone at all. POWER: These headers are the most effective way to increase power on your naturally aspirated 997. On our Dynojet we saw a whopping 20 whp and 27 ft/lbs of tq at 4000 RPM. Peak gains were 10 whp and 17 ft/lbs of tq.  FEATURES: Fits all Porsche 997 Carrera vehicles 2005-2008 Improves horsepower and torque by 15 whp and 12 ft-lbs Saves 2 lbs from the rear of the vehicle One piece CNC mandrel-bent primary tubes provide the most possible flow F1-style merge collectors provide optimized exhaust scavenging Direct bolt-on replacement for the factory headers on all 997 Carreras All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
