I had my Magnaflow comp cat-back installed last week. I love the sound and the 5" tips look cool. I would say it's probably 20-30% louder than stock with a nice deep tone and minimal decel popping. Just wanted to put that out there in case anyone was thinking about getting a new exhaust. I live in so. Bossier and really only drive it on weekends if anybody wanted to hear what it sounds like. I tried to post a video clip I shot but for some reason couldn't.
