I love the sound of this mustang with Mac lth, catted Mac prochamber, borla stingers. I have the stingers and I'm looking to get the other two for my 01 gt vert. What cats should I put on it and still pass emissions.

I'm confused, you want to cut up a pro chamber to put cats on it? Asking because I bet that would probably defeat the purpose of that design. Or at least, it will definitely change the sound. If you want cats, better off going with a pipe that has them already IMO.

Just installed the BBK x-pipe with high flow cats from AM. Have the Borla Stingers as well. LOVE the sound!!
