has anyone used the MAC pipe to replace the cat? I have a factory Y pipe and dual cats and want to get rid of that restrictive crap, thought of getting the pipe and a single cat 2.5" y-pipe for factory manifold (be doing a LSX swap so not really worried about headers). My smog is already gone and i did NOT get any codes, will i get a code with the cats off? what do I do with the o2 sensor? if i get a code how do i get rid of it?
BTW- i know its illegal... I came here from TGO so i dont hear tree huggers opinions lol

Some thoughts:

That $80 pipe sure as sh*t looks a lot like the ones you buy for a few bucks a foot. Shrug

No rear O2 on these cars = no code.

If you are doing an LS swap why do you care about doing anything with the factory Y?

You are a bad person who kills trees.
