not on a bimmer. I have ridden in many M3's with Schrick cams and injectors and the only difference is the slower, deeper rumbling of the engine. It sounds better and feels better, not at all rough. If I were you I would consider some exhaust. Your car sounded awsome from the front but alittle shakey and rattlie from the back.
