This sounds really sweet!
Funny, I placed an order for one shortly after watching this video. But I didn't find this post till today.
Anyways, I ordered the F30 B46 330 system without a DP and opted for the OEM exhaust actuator option. I also have an ER catless DP and ER charge pipe installed, along with a BMS cone intake and a bm3 stage 2 93 octane (agg) tune.
Hoping it sounds like this one!
