I had to modify my crossmember on the driver's side to allow the collector on my Bassani longtubes to clear... I wish I could have used a B.F.H. but ended up cutting a section out and building a new hump to match the passenger side... (you've got your x-member mounted correct, btw).
I might be able to capture a shot for you if you can't figure it out, I'd have to steal my sis's digital cam for a few... let me know.
What I did was cut a 3" section out of the inner part of the hump (tranny side), raised the section that mounts to the body to allow clearance, then added a piece of plate steel to bridge the gap, gusseted the sides, welded it all up, ground the edges smooth, add some paint and viola! ...one modified x-member the way it should have been done from the factory, IMHO
Rather than bending the pipes, just keep 'em straight and modify the x-member instead... Allows you to keep the exhaust tucked up closer to the car and looks "cleaner" when you get done... my 2 pennies on the matter.
edited to add: I used 1/8" (.125") plate steel btw...
