hi flo cat size on 02 mustang with 98 headers
Ok so I'm getting hi flow cats for my 2002 and my question is what diameter of cats will I need, I have 2.5 piping for my dual exhaust with stock cats. I "upgraded" to some 98 v6 "shorty headers". I know the shop had to widen the connector piece for them to fit.. I'm curious what width of cats I'm going to need to fit correctly. Do I look at ones that fit 94-98, or 99-04 or even just 2.5 cats... I'm not to sure which will fit right since nothing in that area is what came on the original 2002 v6. Thanks for your help.
