First, I'd try loosening the clamp and repositioning the tail pipe away from whatever it's rattling against. Even welded, pipes can make noise if they're too close to some other part of the car. My exhaust has to be positioned juuuuuuuust right to keep it from making noises.
The other option is toclearance your exhaust and get rid of the rubber hangers and going to solid ones. That'll reduce exhaust movement to a minimum. Still have to be properly clearanced though.
