Technical Description
The Dundon 997.1 GT3 Long Tube Street Header Exhaust System
Dundon Convertible Street (Catted) tuned length headers and valved side delete exhaust system for the 997.1 GT3 are available now! We were able to keep all of the things that people love about our race headers:
- less weight
- more power,
- great sound,
- quiet when you want it to be
- no drone
- 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!
- Convertible to no cats with the swappable test pipes for track days (available separately).
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 997.1 GT3.
