I'm currently running a Mac 2.5" H-pipe into the stock 2.25" cat-back. I'm trying to decide if the $500 is worth it for a 2.5" cat-back, or if there would be no performance difference over keeping the 2.25" piping and having different mufflers welded in.
i've got some lightly used magnaflows if you're interested.
