Stock exhaust is still steel, bar the tips

We have already started with preliminary development on our direct replacement titanium rear

Also the secondary O2 is on the OAP just before the GPF.
Connection between OAP and muffler is a single triangular shape flange with 3 bolts. Should be easier to swap OAP on this one.
The cutout drawing from Porsche shows that the muffler has similar design to the one in the GT4...the valve open path dumps into each side without gas mixing.
I have a feeling this system can be further improved....

Can you post the drawing?

Some of their setups are focused on zero drone and others to enhance the sound.

I have sitting, an Akrapovic OAP, waiting for the Cargraphic Racing X pipe muffler to arrive and then try out both. My aim is a high pitched "wail" sound, like the video below, which by the way is not an 981 alike sound, is more like an mezger engine GT3 sound. Well if I succeeded at my first attempt then I will be in heaven. I am also betting on that the mix chamber of this muffler will mute most of the drone when valves are closed.

Another important thing that I really appreciate from Cargraphic is that, even in their most extreme setup, they mention that they develop this to maintain the brand's signature sound, which is great!. I also think that Cargraphic doesn't receive much attention in the States because you have a bunch of local manufacturers there, and from that bunch there's two properly engineering companies, Soul and Dundon, but that is... the rest are a no no for me (sadly from previous experience).

So If I didn't had to deal with the EU band straps mount version in my exhaust, probably I would have opted for the less expensive Soul X Pipe. I also want to kudos the Obsessed Garage guy for all of his experiments, they have been key to make my mind of which system has the best chance to be spot on with what I'm seeking.

Finally just a thought about the valve controller, I love the Cargraphic approach, but as time passes by, I think that the OEM controller is just fine. As I have the controller already installed I think that I will keep it there, but I would say that if you will do an OAP and/or muffler, is not necessary to install an exhaust controller.

Anyway I will report once everything get installed, for now my target is this sound:

The various Youtube audio of the SOUL OAP GPF delete mod sounds beautiful...plus it'd be a fairly easy "next step" to add the SOUL valved exhaust system if for some reason I felt that was necessary.

SOUL says they have the 718 4-liter OAP's in-stock. The current wait for the SOUL valved exhaust system is seven weeks according the rep I spoke with.

Same question regarding your Cargraphic exhaust valve controller...did you install it?
EDITED: I don't see a SOUL ceramic coated option for the 718 Spyder...just the basic SS OAP option. Am I missing something??

Don’t need anything else.

ps, I did add titanium heat wrap
