I have a 2017 F06 650 GC and want to get either Corsa exhaust or Soul performance exhaust but I don't see any for the 650, just the M6.

I've seen that the Corsa or Soul exhaust for the M6 doesn't fit the stock diffusser for the 650 but will fit if you change the diffusser for the M6.

Does the stock M6 diffusser (or any diffusser for the M6) fit the 650?

Lastly, if I just do a muffler delete and say forget the fitment issues, will that cause a check engine light to pop on?

Thanks in advance!!
