Hey everybody.
I recently got a 2020 Supra 3.0 in Crimson Red. Really love the ownership.
As some of you EU customers know the car sounds like shit stock. I solved that problem partially with a Remus race axle back which made it sounds a lot better, but I still want a bit more volume since it still sounds a little bit muffled. So maybe I should delete the OPF (but im afraid it might sound too much as the Remus system basically is a muffler delete with open valves). That's why I reckon a high flow cat might enhance the sound a bit.
My question now is - can I still have OPF on the car with a high flow cat? I heard on some bimmerforums that it might cause backpressure and damage the engine.
Would you guys say there's any truth to that?
