ARH 1 3/4″ Long Tube Headers with High Flow Catted Mid Pipes – 2004 Pontiac GTO (5.7L) – GTO-04134300LSWC

We offer a number of coating options at a great price. Header coating makes your car run cooler and perform more consistently. It is not 100% necessary on a stainless header like this, but is great for someone who wants an extra edge at the track and lower cabin heat. Coating will add 2-4 weeks to normal order times. If this a concern, please contact us prior to ordering.
