I think i will go with the JCR titanium rear exhause valved for starter . Anyone had tried just the rear only ? I’m curious about the drone thing . Also k-line also about to release the inconel 625 exhaust so its very hard decision to make

thanks for the help Josh , i really like more pitched sound from exhaust , i made some research but i think Soul’s setup is more aggresive and roary btw i listened the whole setup together i think do you have any sound clip just with the rear ?
Akra does make an OAP that is heat shielded but has the cat in the back to run with a non catted header. Very expensive for both pieces at like $12k, but made of titanium and weighs 24 pounds less. Some of the pieces of each unit are cast in their foundry. Relative to the cost of Mg wheels, the WS package, and adm; maybe not so bad for the ultimate upgrade.
The headers are works of art though for a car guy.

Those are pretty. And those all tie into the OEM muffler? If so, this is the set-up that I might be buying.
I would wait for feedback...what works on the 718 GT4 may not be the same on the GT4RS. If the drone was a problem on the GT4 the GT4RS has more plus you have intake sound, less insulation, different engine, etc.
Most headers/OAP with cats are similar to what Dundon did on the GT4 and this design is the best solution for the 4RS
IMHO I think Soul put a LOT of R&D on their setups and were some of the first to have different systems.
Dundon should be good but very expensive, specially if you add the still pending rear muffler.
JCR is basically following what they did on the GT4
Fabspeed? Not so sure on those....will reserve my opinion on that one.
Still waiting on Cargraphics.
Kline is a good option is you are looking for sound...don't like their header design.
Akra is a mixed bag...their OAP are a good product and a great price, headers like those above? Not sure but they do look pretty and probably expensive..rear muffler? Hate their sound and design...is like the OEM but amplified and way too expensive.
Before you jump into something take a look at the design, how much R&D the company did, any feedback from manufacturer and users.
Some of the stuff out there is just to please people but I doubt it delivers the goods.
