I'll be running a 3" high flow cat with 2.5 reducers on each side, I just noticed that the stock Gen III 3sgte downpipe has a cat built into it. I know some downpipes will kill drill bits and others you can pound out with a hammer if you spend a few hours..lol. I want to hollow it out though, are the downpipe internals hard to gut?

Yeah, I'd be really interested if anyone's done this with a 3rd gen 3sgte as well, I've been contemplating doing it to mine. On my old 5sfe the bottom part of that forward cat off the exhaust manifold broke apart for whatever reason, clogging the exhaust, and so I just gutted the rest of it, and it was pretty easy. Still even passed IM afterwards (since it still had a rear cat I'm guessing).
