540i VSRF Catted downpipe?

OK, so my brain has taken it upon itself to decide that good is no longer good enough, and after much arguing back and forth, I've let Mr. Brain win and have abandoned all hope for common sense etc. It's time to get more power out of the 540i.

MPPSK has been in for a while (that's been great), next came BMS billet intake (also good), and now there's an FTP intake pipe that's just been ordered and is on the way. I've pretty much decided on Bootmod3 instead of going the JB4 route, so that's going to happen shortly as well.
Now.. back to the point of the thread: Downpipe!! I want to run Stage2 and push for around 460 horses, so a pipe is definitely needed. On a rear wheel drive, that should keep things lively enough

Need to keep things legal, so catless isn't on the cards sadly. Is anyone running a VRSF Catted downpipe on their 540i?

Any other high flow options out there that I should be considering? Please chime in if you've got experience with any of the above mix.
