No, favors the driver's side moreso but doesn't make contact at all. Regarding the chassis plate, some have been able to reinstall it, some leave it off depending on how the exhaust is clocked. Can always use spacers there though if necessary.

So the chassis plate isn't needed?thought that helps prevent chassis flexing?

I'm going to have to go with BMW did not put it there because it was unneeded. The VRSF 3.5'' comes with spacers for the brace so you can use it IIRC. I would want to retain the brace. It also would stop your driveshaft from turning you car into a pogo stick on the strip like a drive shaft loop, to a degree.

I have a different 3.5" exhaust but this brace cleared the exhaust on my E90. Barely but it did.

Yeah I kind of think it's there for a reason,if it wasn't then it wouldn't be there especially underneath the car,that stock chassis square plate is pretty solid and has some weight to it.i have the hpf v2 exhaust and mine just clears the chassis plate.i do notice when going to single turbo vs the twins the exhaust shifts little more over with the single,dont know why but have seem this in other guys running the rare hpf exhaust.i would like to get rid of that chassis plate cause then I'll have more swing room.now I'm real close but hasn't been much of a issue.
Kevin,yes I have seen that plate,its a step down.looks nice

Just to be clear, for liability reasons we definitely wouldn't recommend eliminating the brace although a lot of guys do. We would suggest spending more time adjusting the exhaust to clear (lots of adjustment on our setup) or spacing it. The pic of the E92 posted above was installed by a customer not us.
