Hey everyone!! I just purchased a new-to-me 2012 MKZ with the 3.5 and I'm really diggin' it! ...all except for the vacuum cleaner-like sound of the exhaust. I was wondering if anyone had any experience with performance mufflers for these cars. Something definitely not loud, but with a bit of grumble, sort if what a stock Suburban sounds like with its LS motor. Thanks in advance! Scott
