Not got my 125i so can't comment with regard to the exhaust sound as yet. However, I'm coming round to the idea that it won't really bother me so much if the exhaust isn't as auidble as I'd like. After all I've brought the car for a mix of refinement and performance. Also I prefer the look of the stock exhaust tailpipes to the mp exhaust which looks a little to aftermarket for my liking. This isn't to say I won't upgrade the exhaust at some point. Just don't see me being in a rush to do so.
