Pre-Owned 991 GT3/RS Lifetime Center Muffler

At Dundon, we test our products endlessly to ensure the utmost quality. And over time, we found the factory muffler couldn’t keep up with the added performance our Headers provide. We set out to fix that. The result — Dundon’s GT3 Lifetime Center Muffler. We’ve tirelessly tested it to ensure it lasts a “lifetime” and produces maximum horsepower. With two sound ‘flavors’ — Quiet and Loud — you can decide how much noise you want without losing an ounce of performance.

Pre-Owned Inconel Megaphone Mini Crack Pipe

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! 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.
