Dude, I'm pretty sure you can stick a I4 exhaust on a V6...and vice versa...I checked out the underbody of both type accords, of the 1998-2002 generation...and it seems compatible from cat to end. You should have no problem tacking on either kind. I personally love the dual look and it makes the car quiter when not racing...so the cops dont tag ya when you're going to get groceries.
