Exhaust leak at muffler inlet, outlet

The 1997 Cherokee I just got has a bolt-in Magnaflow muffler. There are sooty mraks at both the inlet and outlet showing the U-clamps are not causing a prefect seal -- the leaks occur where the semicircle of the u-bolt fairs into the semicircle of the folded sheetmetal clamp. So I have 2 leaks at each clamp for a grand total of 4 leaks.

I plan to replace this muffler with one that isn't so loud and want to know how to install the new muffler so it doesn't have these same leaks. It would be real annoying to pay the money for a quiet muffler only to hear the leaks instead!

Thanks for your help.

Weld it in or try the band style clamps.
