Any ideas/suggestions or pros/cons? I was thinking of the P2 Dinan Package and E-Series JB4.
Thanks!

Nothing is really bmw approved technically. Dinan has their own warranty to match bmws. I just did bm3 tune on mine and it is night and day difference from my jb4. I would say get a flash tune before a piggy back. As for an intake some cars don't like them. I have a injen intake and my car gets a cel and runs like shit so I got a drop in filter. Dinan intake is one of the only ones that you won't have an issue with. If you can get one used it's not such a hit to your wallet. You won't really gain hp but they do sound nice.
