   The headers features equal length runners, true 3 into 1 F1 style merge collectors, and German-made HJS HD 200 cell metal matrix sport catalysts to improve the flow of exhaust gases. The catalysts are OBD2 compliant to ensure no CEL (Check Engine Light).

   Handcrafted out of US Made T304 Stainless steel, the system is meticulously TIG welded to AWM aerospace specifications with great precision. CNC laser cut header flanges are used to reduce the warping problems due to heat.

   Our GMG 991 GT3 header system is complete bolt-on upgrade. The system will bolt up to the stock primary mufflers, and the factory sport exhaust option is retained.

Highlights:
  • Equal length runners
  • True 3 into 1 F1 style merge collector
  • German made high-flow 200 cell HJS HD catalytic converters
  • Increase horsepower and torque throughout rev range
  • TIG welded using US Made T304 stainless tubing
  • CNC machined extra-thick flanges to prevent warping
  • Direct bolt on replacement, no removal of bumper required
  • Sport button remains fully functional for everyday use

Vehicle Fitment:
  • 2011 Porsche (997.2) 911 GT3RS4.0
  • 2006-2011 Porsche (997.1/997.2) 911 GT3RS
  • 2006-2011 Porsche (997.1/997.2) 911 GT3
