Its most likely hitting the torque box or the upper control arm. I had a similar issue with my catback and it took a few trys adjusting but I finally got it

Thats about the spot were mine was rubbing also check up by the mufflers mine was hitting up there too. It was the angle of the mufflers they were pitched up towards the outside of the car.

What about a loose ballast? I've heard the welds giving out on these can cause this....I believe that is my problem. I put on MAC catbacks after being rear-ended and bending my right catback. Ever since then my right side vibrates HORRIBLY between 1900-2300 RPMS but absolutely none outside of that range. I've re-adjusted the right side 3 million times as at first it WAS tapping the gas tank. At this point i'm beginning to think the colission screwed up one of my ballasts.

Thanks, i will check eath of those spots and i will come back with an update. I will probably have it off the ground in about an hour and i will update.

It ONLY occurs above 45-65 (seems to vary) and ONLY when i let off the throttle. If i hold down the throttle, even slightly, there is no noise.

I just hope i get this annoying problem taken care of..
