I'm leasing my car however I included the exhaust as part of my order. For you however I believe you need to have the original exhaust put back on. My pre-turn in instructions for my current 340i state that any accessory (whether OEM BMW parts installed at a certified installer or aftermarket marks by someone else) needs to be removed. The opposite applies in my case where the exhaust is built into the order and residualized into the lease.

I think your better off putting the standard exhaust back on and sell the performance exhaust for some money.
Thanks for the info! Financially, holding on to the MPE and swapping at lease end makes the most sense as I can try and recoup some of the money spent but any storage space I had is being taken up by my RFTs that I kept for lease end. If there is a drastic difference between the MPE and my stock exhaust I may turn my stock exhaust into my dining room center piece for the duration of my lease.
