I'm contemplating ditching my 1.8T's oem system (the Y pipe is about rusted out) and getting a ss cat-back replacement. I was wondering if anyone has installed a Borla exhaust and can say if everything went in with a minimum of trouble. I'm looking principally at the stainless aspect and hoping the increase in noise will be minimal (I've seen the YouTube videos, but you really can't tell). Thanks.
