R56 exhaust cut-out

Yes, people have. Here is a friends in her blog...

I want to figure out if it could be done pre-cat, but I highly doubt there is room up there as it would a nasty growl. I found a compromise and it was to cut out the 2nd cat and resonator, stock DP and mufflers.

As far as performance is concerned it's not a gain or at least I don't think it is. It's like having the blow off valve adapter. All you want to hear is the woosh. I want to do it for the noise it makes. I already have a magna flow muffler welded in and no res. I did t eliminate the 2nd cat because I thought it would throw a light. Other then that I just want to be a nuisance I'm not going to lie to you guys. I live in a ricer area so it will be fun.
