Thanks for all the useful information guys. I had thought about he 4.8 kit but my sales guy told me that the 4.8 kit will not fit mine, he said that that the exhaust pipes wont fit. Its clear from all of your comments that the bloke doesnt know what he is talking about. I am going to call Morristown Bmw since it seems that they have a better understanding of what kit will work. Thanks again mates.
