I want to rework some of the exhaust. Move the 2 pre cats lower out of the engine bay to help it run cooler. And if I was gonna take the time to pull it apart I'd put a new one in. Only thing I don't like is reading how they have a tendency to crack easier.

Well, since you already have a header as compared to an exhaust manifold you won't see the crazy performance gain like any company will claim. There will be an improvement though.

I just don't see how they flow much better, they are just down to the pre cat, unless te stock 01 manifolds are a lot more restrictive than previous years.
