I looked up the stock part number on real oem and found the 1 series shares the same pipes, but not 3 series. Lucky for me my buddy has a 1 series so I sold him my MMP outlets for cash + his stock pipe. I plan to go custom/ modified oem pipe in all metal. I also plan to wrap these pipes in gold heat tape since they run so close to the exhaust manifold.
For inlets I'm running VTT which are working our great. Install was really easy and performance gain is noticeable. I put down 405whp, 443wtq on 93.
I'd like to add my dyno was on Cobb drop in filter only. If you are doing VTT inlets I would suggest going with some intake upgrade. OP i see that you already have BMS DCI. :thump:
Since the dyno I went with Afe Pro 5R which was also a great improvement. We have to do some heat testing and see if its worth it to wrap the bottom of the heat shield with gold heat tape. I have a full extra
I'll keep you guys posted.
