I have an 08 12S. The clamp that holds the exhaust can broke a few days ago. I replaced it with two hose clamps so I could get home. I rode 300 miles home, and the clamps held. I rode 7 miles to work, and the clamps broke. Is there anything that works better than the stock clamp? I don't understand how they will break after such a short ride. | ||

Either hose clamps or the stock clamps should work, if the muffler is correctly installed. The trick is to tighten the muffler clamps first, and then the torco clamp connector to the header pipe so that the muffler is firmly attached to the bottom of the engine. The clamps that Buell uses are available for about four bucks each from marine supply stores. One such that does mail order is : Deepblue Yacht Supply in Ft. Lauderdale: I believe the rear straps are # 70STBC750, and the front straps might be #70STBC600, but I would measure to make sure. Their URL is: http://www.deepblueyachtsupply.com | ||

I have a 2003 XB9, and the original clamps are holding fine, knock on wood. The two possibilities that I see: damaged from hitting something or being over tightened. On an '08, I guess that would be a warranty item. | ||

I have a set of stock clamps i will take $20.00 for all 3. | ||

Thanks jon. I would much rather get the parts from anyone other than HD. Fran, they are breaking at the top, at the edge of the muffler bracket. Possibly overtightened. For something so simple, I would just as soon do it myself and avoid the hassle of the dealer and the three hour wait. Thanks guys. | ||

That front clamp is not supposed to be reused, and it is a really beefy piece with specific torque instructions. Follow them to the T. I am not suprised the hose clamps broke... and if you reused the original clamp, I am not suprised that broke either. Be really careful, somebody here on badweb has spiffy new titanium holding their leg together after a pole vaulting excercise from a failed front clamp (non factory setup). Somebody saw the same clamps (or what looked the same) at a Marine catalog or something, or maybe an industrial supply catalog. Make sure the bolt is still there. The one that holds the bracket that the front clamp attaches onto the engine. And look for broken studs. | ||

I have replaced many broken front clamp.One new oem clamp only lasted a few days. Marine clamps are cheap enough but after shipping I just went with the oem part, that way you know it fits right. The last one has lasted a while now, I just leave it what seems too loose. Put some locktight on it and your good to go. Jon | ||

Hrrm, weird -- I have done two uninstall/reinstalls with my current straps and no probs. I think the problems on the failed straps come, in part at least, from over-tightening which stresses them to failure point. I marked how far mine were tightened and put them back on to that point (or a smidgen more for stretch), seems to work. Personally I would like to find a better, burlier strap (maybe a kevlar or something temp resistant but fabric, my thinking that a weaved product would stretch and handle the vibration better than a metal strap. just thinking out loud.) but I have yet to find something that seems like it would be better. Going to keep looking though because I want something better for something I see as a critical part on my bike. Cheers and ride safe! | ||

I generally tighten the straps up, then run the bike for a bit to let the slip joint settle, then tighten that. You do need to be quite careful when installing the exhaust. Be mindful of the fact that broken straps are FAR from the worst that can happen. Broken header studs are FAR worse  . | ||

I believe the rear straps are # 70STBC750, and the front straps might be #70STBC600, but I would measure to make sure. Did anyone end up ordering these straps? I'd like confirmation that they fit before I order a set. |
