help me looking for a high flow cat only

[01MustangGT]

i have Mac o/r H pipe and Magnapack catback. it seems pretty loud lately with the KB 9psi. i am afraid that i will get busted without cat. So i am looking for a universal high flow cat that could be welded in my o/r H pipe.
is there any place sell it? if so, which one, or which part number should i get?
Thanks in advance.

Magnoflow cats are what most catted midpipes come with, so I'd go with them.
As far as which one...eeesh...they've got a ton of em. I just went out to their site and tried to do a little shopping for ya, but there are just too many! You'll want the 2.5" of course, but maybe someone else can jump in with some details. Otherwise, you might want to call them.
