you have a few options.... most positive seal is with an automotive type clamp(u-bolt and base, 2 nuts type), ugly as sin though, and it damages the nipple and pipe(crimps a groove in them)there are single bolt car clamps as well, and they are supposed to out-perform the u-bolt type, but ive never used 1, and cant speak from experience.... if you cut 6 or 8 shallow slots in the face of the muff nipple(1/2 inch deep or so) you can get a better "bite" with your clamp... if that's the stock clamp, a harley one is supposed to be a much better clamp... lastly, exhaust pipe sealer... it's a grey ceramic slurry that comes in a toothpaste tube, available at just about every auto parts store on the planet... it MUST be used VERY SPARINGLY!!! Diamond Jim calls it "amish pipe welder" because he didnt...lol (it has made his headpipe and longshot a permanent assembly)... just enough so that the sealing surface looks wetted by it... about 1/2 of the volume of toothpaste you would put on a toothbrush will seal a 2 1/2 inch auto muffler nipple... dont gob it on... just wet.... id say do the slits, switch to a harley clamp if yours is stock suzi, switch to a steel sheetmetal filler(aluminum expands more than steel when heated, thus, it loosens your joint every time it heats up), and if that combo alone doesnt give complete satisfaction, then try sealer...
