I was actually probably just going to have the exhaust exiting right out of the muffler. I prefer to have a hidden exhaust.

BUT, if I would get better performance and sound from the H pipe I think that would be the way to go. Thoughts?

I think instead of gutting the cats cut them out and sell them to me, i'm thinking about putting some back on.
