I actually picked up a used Magnaflow system that is currently on my M3. I really like it!!! Not only was I happy cause I got it very cheap, but it is super light!!! Definitly half the weight of the OEM exhaust... The sound is awesome, expecially on a freeway!!! It does drone a bit at 2-3000 but nothing super annoying!!! My car before my M3 was a Charger SRT8 that also had a Magnaflow exhaust system. That car droned like a mofo!!! So, I'm very happy with the Magnaflow system!!!! If it helps you, I'll make a video and try to post it....

Oh and I forgot that its stated an HP gain of 16.. Havent dyno'ed so I cant confirm....
