RB exhaust knock

My 94 FD had the dual RB exhaust installed when purchased. The rear section is hitting on a frame member near the flange before the muffler section. Is anybody aware, heard of, or maybe experienced a similiar issue?

Its funny that I did not hear the sound of clanking after driving the car home 370 miles!

get the car in the air and see if a hanger/exhaust mount is broke or bent. Bend/repair accordingly. Love that exhaust sound, a bit to rich for my wallet though

The exhaust does sound great once second charger kicks in, but I don't like the fact that it does not protrude from rear bumper very far=bumper gets dirty VERY quickly. The soot is something I will have to live with on the car in general though cuz Turbo Rotarys like it RiCh.

No bent or broken mounts, and snug as can be. I wonder if this is a common problem with this system?? Also have a non-resonated down pipe installed. Maybe this could be the issue as my receipts show that it was a used part when the previous owner had it installed.. Hmmmm.

I've noticed some other systems do not have to make as sharp a bend to the rear muffler which is the reason for the "angled look". Removing the sharp bend would eliminate my issue.
