I recently installed an ER chargepipe on my N55. I can't really comment on throttle response as I installed JB4 at the same time. CP fits perfectly, uses the factory mount and has a meth bung(two actually) as I intend to add meth next spring. I would pull it out before a dealer visit myself, can be switched over to stock in under ten minutes once you have done it once. Looks nice in black as well!
