Not really sure about bms but bm3 stage 1 for me was pretty nice. Car response better and feels it's more awake overall. No sound difference.

If you're gonna do downpipes & air intake you can get stage 2 it will make a huge difference & sound better. bm3 will also burble with stage 2 and downpipes
