First Look...
Iim willing to bet we won't see as large of gains from headers or exhaust in the rcf as we did in the isf. Just from images the factory headers and exhaust they are designed to flow much better. I bet we see 30-40 wheel from the pair rather than the 50-60 you see in an isf
There will be major performance improvements on the Exhaust

^^^^As well as being crushed, the rear pipes (behind the axle) are also of a much smaller diameter than the forward pipes. And here's something interesting, I heard an RCF with both sides of the rear pipes, complete with the mufflers removed, and, to me, it didn't sound loud. The stock mufflers are also smaller than the mufflers on the ISF.

Just listened to clip of JoeZ exhaust on RC-F. It quite possibly is the best exhaust system for the RC-F.
Sounds very burly and muscular, but also very high pitched at high rpms. Sounds amazing.
