Overview
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:
- 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!
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 991.2 GT3.

Some pics installed on the car, the street headers are only about 0.5" shorter than our race headers. To fit everything we had to go up into the wheel well where the side mufflers sit. Only way to get the length required for real power gains...

As you can see to get the length we wanted we had to go up, anything that can bolt up to the stock location is leaving power on the table...

Installed the Dundon Street Header and Crack Pipe combo on my 2016 GT3 RS, and I couldn’t be happier with the results. The sound is absolutely incredible! It completely transforms the car and gives it that raw, aggressive, high-pitched race car sound that the 4.0L flat-six deserves. The way this...
