| We used to just take a stock cat & smash a pipe through it & weld it inline. Last time I did it we took the heat shields off a cat & just tig welded them onto the pipe. As long as the truck doesn't throw a check engine light it will pass for a sticker here in MA. My old PowerJoke would throw exhaust flow codes so I had to put it back on, couldn't get around it.
Good luck! |
