I had some trouble fitting this in my 99 9-3, but with a little force and creativity it goes in tight. I wasn't expecting too much performance increase so it met my expectations there.

If you are looking for "show" then it is un-matched in looks and sound. You'll definately get an ear to ear grin the first time you hear the turbo spool up with it on.
