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
Excellent product!
Fast shipping, great product, got labor day discount applied! Gt3 can finally breathe without the particulate filter.
Everything went great with the installation
Great experience Thanks for the speedy turn around
it was very nice kit
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.

This is a fantastic product that saves time and makes it easy for an individual to change their wheels. The custom case is a nice added value.
Quality is great and fits like OEM!
Carbon Wind Deflectors for 992 Carrera, GT3, GT3RS and Turbo
VERY FAST SHIPPING AND NICE PRODUCT TKS AGAIN GUYS
Perfect fit and easy installation. Noticeable performance improvement on track, especially in longer straights. 3-4 mph higher speed on back straight at Sebring…and sound great.
Perfect balance of sound and performance. My car walks away from other 992 GT3s on the straights and sounds spectacular. Noticeable difference in on track performance.
Awesome
Great solution to Wind buffeting done in style
Carbon Wind Deflectors for 992 Carrera, GT3, GT3RS and Turbo
Great quality matching OEM carbon fiber
Amazing system, when the valves are closed it’s basically oem, once you open them the car screams! Used with catless headers. Greta product!
Great customer service and people who stand by their product 100%
Perfect fitment and adjustability for any occasion, track and street compatible
Fantastic product, customer service, and even packaging. Dundon is a super high quality product and I think the best in the business (I have had other systems from other companies). Easy decision for any Porsche.
