Sorry to say this, but by clamping down the clamps as tight as you could get them started your problems. You have crimped the pipes, now you have leaks, when tightening muffler clamps bring them just tight enough to keep from vibrating loose, Heat water and rust will take care of the final sealing after just a few days, In your case try pulling the pipes apart and use an expander to round out the pipes and try again, Not too tight but just right!!!!
