Dundon Street (Catted) tuned length headers and valved side delete exhaust system for the 997.1 GT3 and GT3RS are available now! We were able to keep all of the things that people love about our race headers; keep scrolling!

*V2.0 Headers shown - Updated 2021

Add Power and great sound and experience your Porsche’s true capabilities with the Dundon Power Package. Intentionally designed to bring big power with and distinct sound we all love, this kit is perfectly tailored to add more muscle, better sound, and increased performance to your specific GT car.

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. 

You Want Great Sound?

You Want Drone Free?

You Want the LIGHTEST muffler for your Porsche?

We've got what you're looking for!  Our Titanium Ultralight GT3 Muffler is all of the above, with a signature Titanium shriek at high rpm, and no bleeding ears on the highway.  Combined with our Lifetime Warranty, and coming in at 9lbs fully dressed, this is the most exclusive exhaust in the world!

Ultralight Titanium mufflers are made to order and a 20% restocking fee is charged on cancelled or unused returned parts.

Take your Titanium Ultralight muffler up a notch with this Inconel 625 Loud Insert.

By eliminating the first expansion on the lower muffler tube, you create an even more visceral experience when the valves open and even quieter upper path when the valves close.
