Rick Case did the exhuast, slotted rotors, and pretty much everything els I've asked. They are not cheap but they guarantee the work, I've bought 2 other Acuras from them, and I got to watch them put it on (they don't seem to have a problem with me being right up under their nose on everything). I've had so many bad experiences with dealerships and shops that to tell the truth I go back in part b/c of their professionalism (Rick Case himself has come down to check my car out and called to follow up with the service). Just my 2 cents...
