Long Tube Race Headers
Long tube race headers for the Porsche 991 GT3, 911R, and 991.2 GT3/GT3 RS, developed with input from Burns Stainless, a California-based specialist in stainless steel header design and Where header primary tubes join into one pipe, shaped to smooth exhaust pulses and improve scavenging.. Built from CNC Bent over an internal mandrel so the tube keeps a constant diameter through the bend, unlike crush-bending. 321 stainless steel tubing, hand TIG-welded and back-purged, they increase and scavenge exhaust flow from the flat-six for more power throughout the rev range. Designed for competition, track and off-road use only: this removes the catalytic converters, will trigger a check engine light, and is not street legal, though it swaps back to stock easily for emissions testing.
