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 40whp max gains on the 991.2 GT3RS, This is the most power from a catted 991.2 GT3RS Exhaust system.

The Dundon Street Headers tested on a 991.2 GT3RS:

+ 40ftlbs at 4300rpm
+ 40whp at 8800rpm

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...

Video from the dyno in the gallery above so you can see and hear the awesomeness! You also get a good shot of how the headers are routed with the wheel off!
