It'll def. make your exhaust sound a little louder, but I guess the main (big) bottleneck that we are going to have with the N55, much like the N54 is the main Cat on the downpipe... You 335 guys will probably have an aftermarket DP from AR or someone else in no time at all, but me with an X5, probably won't have any options when it comes to an aftermarket dp...
