I actually couldnt help myself but study my exhaust when I had my secondary cats deleted. Its an f10, but since I have the N52 engine my exhaust system is identical to that of an e90 equipped with an N52.
why do the newer engines have nothing in the middle of the exhaust? is it a matter of cost cutting or simply removing unnecessary shit. (who the hell needs secondary cats if they have god damn primary cats to begin with?)
