Description
Dundon Street (Catted) tuned length headers and valved side delete exhaust system for the 991.2 GT3RS! We were able to keep all of the things that people love about our race headers.We use 321SS (a superior grade of Stainless steel to the cheaper 304SS) and use a metal core spiral wound 200CPSI catalytic converter. All our products are mfg in the USA in our shop in Gig Harbor, WA.By routing the primaries up and positioning the catalytic converter more vertical we were able to retain 99% of the primary length of the race system. This is how we are able to achieve 23whp gains on the 991.2 GT3RS.
