I purchased the PE after we ordered my wife's 2011 128i Convertible M-Sport 6MT, and installed it the day the car was delivered. It took awhile to "burn in", but 2 1/2 years later, it still sounds great. The one I got came with a clamp and the trickiest part of the install was making sure the original pipe was cut at the proper place to match everything up length-wise. The clamp secured it very nicely without welding so I can put the original back on if that ever becomes necessary. Pretty great sound with the top down!
