These guys are the best!!!! I’m beyond happy with the quality and service I got from Dundon. I’ll forever come back! Thank you guys
Terrific responsiveness and service from Dundon!
Hey guys, I have a Racing Yellow 2016 Porsche Gt4. 6yrs. With Dundon Headers. The best!!! Very 1st mod to my track car. Installed at Dundon shop.I plan to never sell this car it is not stock. FUN car. Thanks you all at " Dundon Motorsports "
Amazing sound!
Installed the Dundon Street Header and Crack Pipe combo on my 2016 GT3 RS, and I couldn’t be happier with the results. The sound is absolutely incredible! It completely transforms the car and gives it that raw, aggressive, high-pitched race car sound that the 4.0L flat-six deserves. The way this thing screams at higher RPMs is just intoxicating. Videos honestly don’t do it justice. You have to hear it in person to appreciate how good it sounds. Best part is I’ve had zero check engine lights or issues with the setup. Everything has performed flawlessly.
Street Header/Crack Pipe Power Package for 991 GT3 & GT3RS (ALL)
This exhaust makes my Gt3 sing!
Being a shop owner, I've seen dozens of exhaust brands. Non come close to the fitment of this dundon system. Fit Like a porsche OE product, sounds like a RSR Cup car. I'm impressed. You get what you pay for!!!
Great quality, fit and finish is fantastic, instructions were very thorough. Installed on 991.2 GT3 Cup, raced it the next day and everything held up wonderfully!
Just installed the full Dundon full exhaust (Street Headers and SS muffler, PVD black tips) on my 992.2 GT3 Touring. The craftsmanship and build quality are outstanding. The exhaust really brings the 4.0L flat-six to life - a must have for .2 GT3. No CEL. Very impressed with the overall quality, fitment and engineering. Highly recommend Dundon!
Great product and customer service!
Sounds burley when I want and quiet when I need it to be
Great service. Awesome working with Dundon.
Amazing customer service!!! can’t wait to get it installed.
Amazing, smoother on the highway over factory and corners on rails. Installer liked the product so much, they became a Dundon dealer!
Dundon Motorsports Suspension Setup Package for 992.2 Turbo/Turbo S
Excellent product that exceeded my expectations. Factory level quality. Perfect fit, and a true cup car sound.
!Great exhaust system! Unbelievable quiet inside the car and superb sound outside. Power gains to be tested soon in track. Regards 🏁🙌🏻

The Titanium muffler and header package has taken my 3RS to a new level. I have often received comments at the track saying that my car is the best sounding car at the track.
Thank you Charles, Jamie, Ted and the crew at Dundon for taking such great care of me and your customers. You guys are a class act and have always gone above and beyond. Much appreciated! Nick

Dundon Motorsports Suspension Setup Package for 991 Turbo/Turbo S
Excellent support and quality of parts for my 997.1 GT3 RS. The tolerances and quality of the parts are perfect
Amazing! Love the sound and the added throttle response—it’s like the GT3 just woke up and is ready to play. Absolutely transformed the driving experience. Great job, Dundon team!
Dundon never disappoints! Installation was a breeze and everything fit exactly like you would expect.

Perfect fit…would recommend!
Great experience. The spacer kit was exactly what we needed
Good Fitment! Thanks again.
Thank you guys! System turned out great. Sounds amazing. Tech support from Ted and Charlie was first class! They really went above and beyond! We really appreciate your partnership.
I received the Accessport device very quickly from Dundon, and found the process of uploading the ECU maps to be a simple and smooth process. I previously had OTS tunes from Softronic and Cobb, but I have to say.. what a remarkable change the custom one from Dundon has over the others. The support from both Charles and Jamie has been great. They provided useful context and slight revisions to the tune based on performance data logs that are captured by the device. The tuning is still ongoing, but I’m very pleased with the results thus far. Highly recommend!

Great quality! Just print instructions and make sure to print template at 100% . 67 lb paper is perfect for template..
Amazing customer service and the most amazing sounding exhaust ever. Discovered a hole in the muffler of my GT3 and they found a replacement and had it to me the next day so we could install it for upcoming weekend HPDE. Fits perfectly and sounds so much better than the Porsche stock muffler. Can’t thank Dundon enough for their product and service backing it up.
These are the same as OEM, but much more convenient when they arrive with the exhaust so I don't have to run to the dealership and grab them.
We had a combination of the Dundon headers with the crack pipe exhaust and decided we needed a change after getting black flagged at our local track for blowing clear through the noise ordinance. Dundon's quiet muffler reduced our noise to an acceptable level and still sounds great. The quiet muffler removed any drone we had with the crack pipe and made driving the car much more reasonable. If we need to reduce sound levels more, we can easily add the quiet tips - it's nice to have modularity.
