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.

*Note the 992 Ti Muffler needs our street headers to fit on the 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. 

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.

The 997 GT3 and GT3RS are amazing cars, but the factory suspension has limited adjustability, leaving you a narrow range of available settings. Our suspension arm packages really open things up, allowing you to get a "proper" alignment on the car for better tire wear, improved handling, sharper steering feel and a better driving experience!

Our meticulously designed and carefully curated suspension packages are built to give you the improvement and adjustment you need. 

These packages will allow for a precise and accurate alignment with a wide range of camber, toe and caster settings. These adjustments open up options for different wheel & tire fitments. They also remove rubber from the suspension system, improving steering feel and the driver's connection to the road.
