Add to everything else, make sure you torque it to the required specs. Not just to what you think feels tight enough. Check your service manual. I think it's 46 ft lbs, doesn't sound like much but it is.

After thought, check to see if you have the pipes seated as far back as they will go. Put the clamp as close to edge as you can. Helps with leaks too..

 

Something I've done for years, and has always worked for me. Of course new clamps. But before you slap them on, put a nice fresh seal of anti-seize around the exhaust header pipe right at the end where you're slipping on the muffler. Torque to proper spec, and your done! It's always sealed great for me, no slippage, and when it comes time to take that set off, and throw another on, they come off a lot easier. You might not find this in the manual, but years and years of doing it has made me a believer.

 

i found out the hardway also now i always put new clamps on.

 

The muffler clamps on my bike wouldn't stay tight so I took them off and formed them a little bit so they would clamp down smaller. They didn't appear to be made quite right. Haven't had any problems with them since and have removed/replaced the mufflers several times since then. I don't see a need to replace clamps.

 

^^^^ This is the 100% correct answer. It might be spelled "Torca" but I could be wrong. I am too lazy to look it up. I bought a bunch of them a few years ago but I don't remember what they cost. Didn't seem unreasonable.

 

You're correct, it's "torca".
