I'm not an expert (you could PM getBMWPart's reps here, Evan@Tischer or Jason@Tischer for a definitive yes/no), but that kit looks like it includes everything you need including the bumper and diffusor. The description says you have to order one extra small part for non-335s. Painting is required of course. This is assuming you're going to stay with the standard one-sided exhaust setup.
