    Hi I saw your post about drilling holes in the cats and was wondering where I should drill becAuse there driver side and passenger side and in the middle some what I have seen. Also I have seen new cats on eBay for pretty cheap. Thanks again in advance

    Just drill 3 3/16 holes on each of the two side cats in the direction where they're not going to vent on anything critical and you'll be fine. It'll run and drive great but sound like **** but who cares. It'll at least hold you over. I got my full replacement entire 3 cat assembly y-pipe from Rock Auto for I think 475
