what about power? Any dyno graphs before and after?
I never got around to do a base dyno so not looking into doing after the mods....maybe @Soul Performance can post some after more people get their systems.
Spent some time on the phone today with John, got competition OAP's, Jet Coated, ordered for the 4RS. Thanks for your time today John, great customer service.

I did the same, resonated over axle pipes.
Me too...
My Soul non-resonated (competition) GT4 RS OAP's look like they will arrive this Thursday!
It was truly a labor of love, but our latest pride and joy is on full display! We'll have a lot more to say on this and everything else we've come up with, but for now here's a quick look.

Correct, with the drone canisters the system won't fit with stock OAPs. Once we get the Package details sorted out and listed, that will be the main page we'll direct to. But the rear system itself is also offered in case anyone uses a different company's OAPs.
We'll have a full video of John going over all the details soon!
Here's some feedback on the header/street OAP system with OEM muffler.
The sound is much better than stock and with the valves closed it's OEM "quiet", once valves open it rips, specially at the upper rpm.
No drone, zero which is very important as my car is still used occasionally on the street.
I'm really surprised that with a similar setup the 4RS sounds different than the 718 GT4.....the sound from the engine is better and I don't think the OEM muffler has anything to do with it.
Power wise, feels it revs a bit faster...no dynos as I never took the car full stock for a baseline. But it does feel it adds a bit more punch.
I can imagine this system also drops a bit of weight from the car.
Very happy with it and John is always a phone call away to answer any questions.....thinking now of adding their new valved muffler and hoping is not taking it too far like it happened on the 718 GT4.

Nice to hear, my plan is also to get headers and OAP pipes while keeping the OEM muffler because I loved how it sounded doing that on both my 981 GT4 and 718 GT4. As you mentioned, I had zero drone with that set up on both cars.
I wanted to get past break-in before putting my OAP's on, but I just hit 1K miles and have a set of Soul no-resonator OAP's I need to make some time to install.
