Looks like the 2022 TS version is a bit different. Maybe our OPF isn’t as accessible. Looks like our cat is easy to get at, but not our possible opf IF opf always comes after CAT.
EDIT: Found photos of both exhausts on line, definitely doesnt look like Turbo S's get that fake material added. Oh well.. no 'free' route to making the Turbo S LOUDER

get high flow cats, bmc filter and tune. Sounds like the apocalypse
I also heard that dundon is lying to there customers stating that the street headers package doesn’t need tune, supposedly that is false the car is always in a state that it’s about to throw check engine lights…
please don’t kill the Messenger I don’t know if this true or false only what I’ve been told!
For north america … it doesnt need a tune. The cel is certainly from the need to recalibrate the valves once swapped over. Which takes 30 sec with a piwis tool. They are also completely transparent about this.
would also be helpful if the cleaning ladies you heard from scanned their codes and said what the cel are. 99.999% its gonna be valve operation related, which is instantaneously fixable
for what its worth, nobody tests the system as hard as dundon. NOBODY. They have master porsche techs, all the porsche software, an in house dyno which they dyno’ed every single GT car pretty much ever under completely identical conditions, and a race driver to test on track.
also the hjs cats every other manufacturer use are 20 years old. The ones dundon use look like alien tech and are as good as oem if not better. Also comes with new porsche gaskets and mahle hardware its quite impressive
you get what u pay for

Wow…. Big words to say we’re lying and your just the messenger, and have a competitors parts on your car. Seems convenient….
My personal car doesn’t need a tune, needs the valves calibrated.
Ray Morts car didn’t need a tune, just the valves calibrated.
Rennolazine’s car didn’t need a tune, just the valves calibrated
About 7 others both cat back and header systems no issues except needing the valves calibrated.
Canadian cars fine. Speedsters fine. Euro cars and other cars not fine, they need a tune. And we have them installed and tuned in Asia and Europe.
Any component be installed incorrectly and cause a CEL, sure. Leave your gas cap off and see what happens.
And this singular person is why I grow so so weary of Rennlist.

i could care less about jcr or dundon I have no interest in your company success or failure.
I’m also glad you came on here to set the record straight! Now I have more confidence in removing the opf…. Thanks!
Wow Dundon is known for its engineering and high quality. While I joke about some hp claims, there is no doubt they are a top tier company with solid engineering. To trash them seems a bit childish and misinformed!

I’ve spent so much time hanging with Jamie and their enthusiasm and engineering prowess is second to none. He is one of the most honest guys I know in the aftermarket world. Charles Dundon and Jamie have built their company based on their reputation, Insanely good engineering and better than OEM manufacturing.
Dundon is generous and has contributed so much to Smokies GT’s charitable efforts. Far more than any other exhaust manufacturer.
If there is an issue, they will always make it right. I went back and forth shipping exhaust parts across the country until I arrived at the perfect setup for me on my 991.2.
Pisses me off that you have the nerve to dive in and smear one of the most credible companies out there on a public forum. Because you “heard something”.
Wishing you a series of terribly frustrating and impossible to diagnose CEL’s… you deserve every one of them.

like I said this is something I was told I felt like it was my obligation to say something.I’m glad dundon came on here and explained.
technically it’s not plug and play if it need the valves recalibrated.
