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 25whp gains on the 991.1 GT3.
You get everything you love about the Dundon Race Headers; 321 SS construction, industry leading power, lifetime structural warranty, and 100% money back guarantee, if you try it and don't like it, send it back we'll give you your money back!
