Once you get a decent quality exhaust strap, look at the alignment of your whole exhaust system, it sounds as if there's a deeper rooted problem here than just a misaligned strap that is breaking frequently.
Also check the other straps and mounting rubbers elsewhere on the system, they may provide a clue as to what's going on.
For the record, i fitted a complete system from ECP to my old 740 including their silncer straps and never had a problem because i made sure everything was lining up as it should before tighteneing the strap bolts and the joins, whether they were "U" clamps or flanges.
They were all done up finger tight cold then i started the engine and let it warm up and once the back end started getting warm, worked my way from back to front tightening the join then the silncer strap on each section.
Had no problems with any of the straps.
