Of course you don't get as much hp gain compares to downpipe with cat-back exhaust system. Which this will also explains whether you need the MPE first.

If you are worry about warranty and issue on the lease, I would suggest you to keep the car stock.

I have BMS JB4, coilover, catless downpipe on my F10 and BMS JB4, Brembo, lowering spring on my F15. I always bring my car in for a service with those attached.

Oh, on the side note. Not all mods are street legal.

What dealership do you go to for service?
