I've seen pics from at least one US spec 3RS with OEM headers removed in preparation for replacement, and they had the OPF. I have not taken my exhaust apart and don't intend to for a while - going to drive the car as is and decide later. Anyway, not sure what to make of the conflicting evidence here - if you've indeed seen OEM headers without OPF material, the inconsistency in US spec cars doesn't make sense...

Can't explain it. Maybe its a revised design with a smaller OPF package - could very well be that now that I look more closely.

GT3 header on Soul website. (That looks very different than what I saw. There is about 3-4" deeper starting point for the material that's in there on the RS header I saw on a bench for a car here in Austin. Hard to say if it's OPF or catalytic matrix.

the driver-side headers are deeper indeed which might be the side you had your eyes on.

The US RS’s definitely have OPF material. My car is at the same dealer mentioned a few posts up and having headers swapped to aftermarket as a result.

My guess is you saw the black one? We're still waiting on the exhaust (in transit) before beginning mine (white/green). Thank you regardless :-)

Ah yes, the black one is the one I'm referring to in this thread, but I also saw pics of your tribute - killer spec! I took delivery of the Shark Blue car back in April.

75 posts and not one reply to the question of drone after removal of OPF material...

So to those who removed the OPF, is there any drone?

TIA

Maybe I missed it but how much HP do they pick up after you knock the OPF out ?
