Want less weight, more power, great sound, and no drone for your 991.1 GT3? You've found it in our Long Tube Street Header Exhaust System.

Dundon Street (Catted) tuned length headers and valved side delete exhaust system for the 991.1 GT3 RS and 991.2 GT3 and RS 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
We use 321SS (a superior grade of Stainless steel to the cheaper 304SS) and use a USA made 200CPSI catalytic converter. All our products are manufactured 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 30whp gains on the 991.1 GT3 This is the most power from a catted 991.1 GT3 Exhaust.

The Dundon Street Headers on 991 GT3 make:
  • 434whp peak
  • 30whp at 8215rpm
  • 26lbft, 23whp gains at 4586rpm
