991.1 GT3RS and 911R Long Tube Street Header Exhaust System

Dundon Motorsports' 991 street header exhaust system is the elegant solution you have been waiting for!

This system features stainless steel construction that will withstand the most extreme conditions on the street or the track, while saving weight compared to the OE system. 

Tuned length primaries lead to a high quality catalyst with minimal pressure drop, then onto a valved secondary that retains the function of the PSE button. No check engine lights, and no tune required!

Dundon Street Headers on a 991 GT3RS makes 445whp peak, 34whp at 8400 rpm, 29lbft and 24whp gains at 4478 rpm.

Like all of our exhausts, this product includes a lifetime warranty, a 30 day money back guarantee, and is made in the USA.
