Nissan 370Z Forum - View Single Post - Fancy Tech: How to Get Rid of Exhaust Drone, works great!

I have been going back and forth with Fast Intentions to try to understand all this, and figure out how I can get s/c-compatible cats while retaining the OEM Nismo muffler. I'm embarrassed to say I still don't get it. I've crawled underneath the car with a flashlight, and this is what I think I see:

cats -> H-pipe with resonators in very back (?) -> muffler

I can't even seem to find a Nissan diagram that identifies the different sections of the exhaust. What I think Fast Intentions is telling me is this:

resonated test pipes -> lead pipes with 100-cel mil spec cats -> X-pipe with resonators -> muffler.

The lead pipes won't fit the OEM system, so you're stuck ordering the whole exhaust which I don't want to do. I want to have cats, but how do I get them downstream in the OEM H-pipe?

Please correct me if I'm not understanding this correctly!
