Ripping out the opf material
#121
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.

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.
