I'm looking at what I need to replace my stock cats. Can anyone tell me what size pipe go in and out of the cats? From the sound of things I will need to purchase a couple of universal ones and have them cut & welded into stock exhaust (I already have someone to do this for me, but just need to have them first). I think I have found a couple but not sure of size input and output, 2", 2.25", 2.5", 3"??? Thanks for your guys help. I've probably missed where this info was before, sorry.![]()
