has anyone done this( an OEM) ISF exhaust used on an is 350, the routing is the same( under car) may need slight mod to mount to is350 stock header( nothing any exhaust shop cant handle), but would be a less expensive option and flow better than the oem is350 exhaust( and not be crazy loud too) probably flow better than most aftermarket exhaust for the is350!

I noticed the other day RVCAis250 has an ISF rear on his 250. Hopefully he will see this thread and provide some insight because I don't know if he as the actual exhaust system of just the rear bumper.

RVCA has a Modded IS350 HKS exhaust behind the tips i believe....
