Wow.... such hate for Magnaflows? I have Magnaflows and they sound pretty damn good if you ask me.... also took the mufflers off at one point and just had tips.... sounded incredible, like a Nascar above 3500 rpm, but 15 minutes at 72 mph on the 15 freeway drove me nutz! Talk about frickin drone. Not to mention it sounds like I'm going 120 when i'm actually going 20.... couldn't hear my bluetooth in the car, so the mufflers went back on (do miss setting off car alarms when I started my car though, made the damn ground shake

).... FYI I bought the car with Magnaflows already on it. Not sure what kind they are but sdunham's write up is pretty accurate.... Sounds relatively tame at idle, but step on it and it'll make a little bit of noise (and by a little bit I mean a hell of a lot more than a stock AMG exhaust). Plus, Magnaflows have a straight through design..... To each his own, but for an upgrade option that is relatively cheap I think the Magnaflows are a pretty good option. Granted, if money were no object, I would have the eissenmann exhaust..... but if that were the case, I'd also have the sl65 black series arriving shortly too..... needless to say, I can keep waiting cuz it's not coming. If anybody is interested, I could take a short video with my camera and post it.
