You should try downpipes first and see if that is enough. The N55 sounds really good with downpipes.
If not, the majority of exhausts available will sound good. The drone typically becomes more apparent when the cat back exhaust is mated with downpipes. So you need to decide first how loud and if you will ever have downpipes in conjunction.
