Unfortunately I haven't been able to really test it as the car has been sitting at the dealer for better part of the week due to suspension issue. Is what I'm feeling correct?
Youll have some more exhaust noise, but there should be no real change with vibration. Be sure they have bolted it in to the mounts there.
To me, the car feels sluggish even stock in comfort mode so its hard to tell. The turbo does come on stronger once spooled as you feel the TQ im sure. Hopefully you get your cat back soon so you can give a better driving impression.
