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?
