Hey guys, I'm a new 2010 CTS Premium owner with 34k miles on it. And LOVE IT! I mean WOW! What a car! Easily the best car I've ever owned! Anyway, I was wondering if anyone has ever put a Flowmaster muffler or any other aftermarket muffler on their car? I used to put them on my other cars and trucks back in the day, however, I'm not sure if it's appropriate on a luxury car. Or, not sure if it will sound right on a sedan. Any feedback is appreciated.
