911 S/T Performance Products

The Porsche 992 GT3 and 992 GT3RS Exhaust systems leave much to be desired for improved performance, added power, and improved sound. We designed a long tube header, keeping the valves and no check engine lights, to dramatically increase power and fantastic sound.

We keep the valves for easy cruising, better than 200 cell catalysts, and allow you to experience the sound you love from our sublime Ultralight Porsche Titanium Muffler, to the Porsche RSR craziness of our Inconel 625 Crack Pipe. 

Your new 992 GT3 is an amazing car, but we feel it's lacking in the sound department!

Improve the sound of your 992 GT3 Exhaust with Dundon Motorsports' Cat-Back Exhaust System! 

No CEL, no codes, no lights, just that great Dundon Sound!

We'd been asked by a few to make a Crack Pipe that wasn't as much of a commitment but still true to the original Megaphone Crack Pipe. Meet the Mini Crack, this one works with Dundon valved side muffler deletes or our Street Headers, for both 991 and 997! 992 cars will need our cat-back kit or our full street header package. The only sound better than a Porsche is the sound of a Porsche that’s earned its racing stripes. That’s why we’ve designed the Crack Pipe — the ultimate, unbridled expression of Porsche’s Motorsport DNA (with a little help from Dundon Motorsports). If you want to seriously turn heads at the track when you fly by, this is the one for you. It's still loud but the valves do take a bit of the edge off while cruising.
