JCR titanium silenced valved race pipe was delivered today! The quality is exceptional, and it's also very very light. Hopefully I will have time to install it this weekend and make some noise! Might have to plug the valves back in to avoid drone given I already have Akra over axle pipes, but I will run them open first to see what it's like.

Doesn't a rear section like this close the gap in tone between valves opened and closed? Looking forward to the review!
That is my expectation compared to the stock delta between valves open/closed.. but I also went with the silenced version that should quiet down things a bit more with the valves closed.
I have just the JCR rear section on now. Sounds epic. Its not loud as the OEM OPF deadens the sound and prevents drone.
I've done a few combination setups already so this combo shall be interesting...

Beautiful! Cannot wait for my full OPF delete and race pipe from JCR to show up. Covid and customs from Brexit have delayed it for months.

Looking forward to your take on this, we have the same parts just installed in a different sequence! I installed the Cargraphic controller first and noted that even the completely OEM system exhibits drone from 1800-4000 RPM. Next I installed the JCR Silenced Race pipe and was treated to an amazing clean exhaust song from the 4.0l flat 6. At this point the sound was a pretty much pitch perfect, drone was there but with the Controller set to Auto (OEM) and the valves closed in the Drone Zone (which now was truncated to 1800-2800 RPM), given' her the beans with the valves fully open it is incredible and befitting a true GT car, perhaps needing just a bit more intensity(?). The final piece was the Akra link-pipes, this uncorked the system and you got more of everything, the intensity was now perhaps a little over the top for the street but can be managed with the right foot and valves in Auto (OEM) mode, I will say that the volume of the drone increased as well, again this is where the Cargraphic controller really helps, set it to Auto and it really helps.
Should you want to be noticed all you have to do is set the valves to Sport (always open) and rip through the first 2 gears, no doubt about the engine sitting behind you either from the drivers seat or on the side of the road, the 9A2 Evo 4.0l now has the bark to go along with the bite!

Nice! I love how the titanium turns blue after some good use. I'm guessing I'll end up ordering the Cargraphic valve controller like you did to control the drone when desired, but I'm really looking forward to the true flat six sound of the merged JCR rear system! Hopefully I can carve some time out this weekend to work on it in the garage.
