  1. 2005-2010 Mustang Talk
    My car had blown out a catalytic converter last year and it has had it's check engine light on since. I'm due for inspection this month so I finally got around to putting on a new catted mid-pipe. I installed a bbk x-pipe with cats. It sounds good. It's quiet on the highway and pops ever so...
