    Right now I am ripping my Seville STS 2003 apart in trying to find a elusive misfire but upon putting it back together hopefully issue solved, I’m gonna be deleting the cat and installing a 3” pipe back to some muffler brand not sure yet. I’m gonna do my best to follow the stock exhaust path...
