I want a high flow cat for my 91 xj. I already have pacesetter headers and a thresh muffler and want to know what would help the sound/hp without breaking my bank. I need some help with what I should get

Magnaflow makes a decent high flow cat. I picked one up with a flowmaster delta 40. Not too shabby.
