Our Most Popular Package. Street Headers and Lifetime Muffler!
Dundon Street (Catted) tuned length headers and valved side delete exhaust system for the 991.2 GT3! We were able to keep all of the things that people love about our race headers:
quiet when you want it to be
lifetime structural warranty
100% 30day money back guarantee
if you try it and don't like it, send it back we'll give you your money back!
We use 321SS (a superior grade of Stainless steel to the cheaper 304SS) and use a metal core spiral wound 200CPSI catalytic converter. All products are manufactured in the USA 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 991.2 GT3.
