Im getting close to doing something about the wimpy rear end of the 640i.
Want to go with m6 diffuser and hopefully with these clampable 650i style tips below with an ID of 67mm.

Please have a look, do you think i would be able to fit these to my 640i without cutting off the pipe? Would it stick out too much? Where exactly does the exhaust pipe terminate behind the diffuser?
I dont want to cut any pipework... want it to be reversible... Hence this route.
