Very helpful, thanks for the input!
We do not, its not feasible to create a modular header with cats without compromising the primary design. Dundon have a great solution for those who wish to run cats but we do not want to produce a non modular header so we will be sticking to only our catless design with the JCR Inconel Race Manifolds
With the exhaust button 'off' the valves will open when the torque requests reaches a critical amount but its possible to drive with low load and never have them open. Obviously if you get into the throttle beyond that threshold then the valves will open in order to avoid excessive back pressure.
Personally this is not something that we would recommend. It would be possible but not advisable.

When the valves are closed on the valves JCR pipe, would it remain close throughout the Rev range or would it open at around 4k rpm?

For anyone that's installed this system, I'd appreciate a real-world update. How is it to live with for regular street driving? Relative to stock exhaust, how loud is it when in silenced mode running steady throttle on highway and secondary roads? Any additional videos would be much appreciated as well.

Will do....once I receive mine.
Looks like mine is still two weeks out though. I'm waiting patiently...

has anyone got theirs yet? Want to know the transition on the valves and if there is drone. i have side deletes and cannot tell if there is drone, I am guessing this will be low to no drone.

I currently have the race pipe fitted. I can’t wait for the valved version. Should be absolute best of both worlds.
I’ll give my thoughts when I get the car back!

So, how do we think these will go passing sound at Sonoma and Laguna Seca? I'm assuming not? What about their bolt on tip silencers, would that get you passing sound or would you still need the GPS controller to turn off valves?
