How about checking with Dundon first to get details before blathering it onto the forums. They would have answered you the same day and you would have been able to make an informed post vs posting “something you heard.”
Dundon and so many other aftermarket companies rely deeply on forum reputation.
I’m not usually this critical but I’ve seen first hand how hard those guys work and how stand-up they are. They simply don’t deserve this.

its not a complicated issue its literally one of the easiest things ever. Under 1 min for me and any porsche shop with a piwis or dealer can it. It so happens many of the first dudes that slapped on dundon did it themselves. It should be in the installation instructions (which i didnt read lol). Also, literally everyone uses helical valves from the uk (except akrapovic and they have the worst and most rattly valves in my actual experience). Im certain people will run into the recalibration issue when they get valved systems from lots of places because the spring mechanism is different. And its not even an issue. My dealer did it for me in the parking lot because it would take longer to put the car in the bay than just zap it

if its not valved u dont need to worry about cel. I also have a cargraphic valve controller and it actually blocks the cel due to valves being off.
i think with a full header system where the flow is engineered to be ferrocious the valve calibration is important. Even if its 10-15% off it will have different flow on each side.
i had my valves calibrated anyway and my buddy who installed full kline is getting his calibrated even tho he runs wide open most of the time and no cel

The valves need to be calibrated with a PIWIS post install. Never hid this, look at any of our social media posts.
We’ve said it over and over again on social media. In person, to those that have ordered. It’s in the instructions. Plug and play means no engine tune is required.
As far as gutting the expensive stock OPF, I’d be a little leary as the next owner may want them, trade in for an RS will require them…
Thanks to all who came to our aid, very sad times when someone leads with “they lie” instead of just asking a question….

The OP was asking about taking out the OPF material from the factory OPF's. Just stating the obvious that:
1. They're expensive.
2. If you trade In the car at some point, Porsche will likely want the original equipment on the car.
3. The next owner of the car will want them (or should want them).
4. You can't just "put the back" as you have to bust them up to get them out...

Lol,
The OP was asking about taking out the OPF material from the factory OPF's. Just stating the obvious that:
1. They're expensive. Not really.
2. If you trade In the car at some point, Porsche will likely want the original equipment on the car. No, they will never know in the US.
3. The next owner of the car will want them (or should want them). No. What, why?
4. You can't just "put the back" as you have to bust them up to get them out...

Take a look at the sound difference. Sorry for the limited clips but the first is pre opf delete the second is opf material delete.
the sound is deeper at the lower end and oh boy it’s raspy at the top end.
