991.1 GT3 Products

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. 

Want less weight, more power, great sound, and no drone for your 991.1 GT3? You've found it in our Long Tube Street Header Exhaust System.

More filter area means slower air speeds through the filters and less pressure drop across the filter element. The 93mm Throttle Body has 28.6% more area than the 82mm throttle body.  

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. 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.

Get the extra camber you're looking for 1-1.5* more just from the camber plates.

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.

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.

Why do you need adjustable sway bar end links? To ensure perfect corner-balance and zero pre-load on your sway bars with Dundon Motorsports' NEW adjustable sway bar end link set (front & rear).

When your 991 GT3 or GT3RS is corner-balanced or even just sit in it to drive on track, it will put pre-load on the sway bar because the stock end links are not adjustable. This adds additional spring load to one corner of the car, creating an imbalance from left to right. Our adjustable anti roll bar end links ensure there is no pre-load on the sway bar, and that your car is predictable and friendly on the road and the track!

Fits ALL 991 and 992 GT3/GT3RS Models

Features: machined aluminum plates, 10.9 grade pressed-in studs, high quality monoball bearings.

Clone - an exact copy of the original. In our case we're talking about taking the fear and anxiety out of having a tune on your GT car and extracting and tailoring the ecu to take the most advantage of your modifications in a safe and professional way!
