Just be aware, there were 3 different exhaust setups with the N55.

One base model cars, you have the standard chrome, round tips setup.

On M Sport cars, I believe the muffler was the same as the base cars but the tips were oval & chrome to match the M Sport bumper exhaust opening.

Then there was the true M Performance muffler. This ditched the valve on the passenger side so you had exhaust gasses flowing thru both tips all the time. Muffler sounded more aggressive. Tips were oval black chrome.
