  • Universal O2 Spacers with Catalytic Converters scrub the exhaust and lengthen the distance between the O2 sensor(s) and the exhaust flow to reduce the chance of a CEL.

These free-flowing race headers remove the factory catalytic converters for the most flow possible; designed for maximum power and sound for race and track applications. 


These headers will give you a very significant increase in volume and ripping sports car sound due to the removal of the factory catalytic converter.


These dyno designed headers feature smooth mandrel bends and a 3-1 collector to get the most power out of your 991. At 6500 RPM there we saw an increase of 27 whp and 26 ft/lbs of tq. Peak power was up 5 whp and 9 ft/lbs of tq. 


  • Fits all Porsche 991 Carrera vehicles 2012-2016

  • Adds 27 whp and 26 ft-lbs of torque at 6500rpm

  • Saves 4 lbs from the rear of the vehicle

  • Made for track/off-road use only

  • Constructed from equal-length T304 stainless steel C.N.C. mandrel-bent tubing for improved torque and equalized engine pulsing

  • More power and torque across the RPM band and dramatically improved sports car sound

  • Includes multi-layer exhaust manifold gasket

  • Direct bolt-on replacement for the restrictive OEM headers with no cutting or welding required

  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

NOTE: Optional 02 Spacers are available to prevent the Check Engine Light from being triggered.

INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.

DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only, never to be driven on public roads. This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars.

    These are just as described. They let a far better sound out of your Porsche. I was very impressed and the lower tone is fantastic.
