Hardware Kit to Install a 321SS Lifetime Dundon Muffler on 997 and 991 GT3/RS cars. 

Replacement tip sets for your Dundon Lifetime Muffler ONLY. Does NOT fit OE Porsche Mufflers. Proper tip length is important, so please ensure you select the correct application. 

The Porsche 992 GT3 Exhaust and 992 GT3RS Exhaust system leaves much on the table for improved performance, added power and improved sound. We designed a long tube header, keeping the valves, no check engine lights, to get dramatically increased 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. 

Tap in to your Porsche GT3 and GT3RS true capabilities from the motorsports world with the Dundon 992 GT3 Exhaust and 992 GT3RS Exhaust Package. Dundon's enthusiasts passion to offer GT3 exhausts made with 321 Stainless Steel, designed to bring big power, no check engine lights and the distinct sound we all love, this kit is perfectly tailored to add more muscle, that cup exhaust sound, and increased performance to your 992 GT3.

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. 

Dundon 981 GT4 Race Headers provide substantial gains in torque and horsepower throughout the rev range. They are a race system so are for track or off-road use.

If you want to seriously turn heads at the track when you fly by, this is the one for you. Fair warning — with no valves or mufflers, you’ll have a constant RSR scream that is LOUD. So we wouldn’t suggest taking grandma for a spin.
