I saw different post on this topic but didn't get the answer I needed before I buy one, 2002 Mustang GT

Without having to.... What? I don't know if there's more to that, if so then the app doesn't show it. Are you wanting to put an aftermarket mid-pipe with high flow cats in? If so then they come with 2 cats instead of 4, they will work just fine but you may fail emissions since you have 2 instead of 4 cats (depends on your local emissions laws)

Are they cutting and welding on your current mid-pipe? I would just buy a nice Bassani or Magnaflow catted X-pipe and have them install it. As for the cats themselves Magnaflow and Bassani both sell them. Is there anything wrong with your current cats?
