Default Muffler Clamps

The clamp on my right muffler (the one that comes off the most for tire changes) has stopped holding the muffler tightly. The muffler is in no danger of falling off because the rear mount will only let it slip back so far. I bought some new ones at my dealer this morning and they are, in my opinion, reasonably priced at about $7.50 each. I believe the manual recommends replacing them every time you remove a muffler but that's a bit excessive as I've had mine off quite a few times the last 3 years and this last time was the first time it failed to hold properly.

Has anyone here removed or modified the "spacer" in the clamp or shimmed the clamp to compensate for the stretching of the clamp from multiple uses? I see some aftermarket clamps that don't have a spacer at all.

I've noticed also that the clamp for my short crossover under tube connecting pipe won't hold the left side solid (will rotate up and down.) The exhaust bushing doesn't look to be damaged, and the clamp is as tight as it will go. It doesn't appear to be leaking exhaust gases.
FWIW on my 2014 SGS the two muffler clamps require a 15mm socket, and the crossover clamp uses a 14mm or 9/16".
I was also wondering if a new clamp would fix this or not?

The crossover uses a different clamp and for some reason it is nearly 3X the cost of the muffler clamps. It appears to be pretty much the same clamp in a different diameter.

Personally, I just replace the clamps if I have to remove them, which for me is rarely. Not too pricey and that's what the manual says to do, so...

You can use aluminum foil as a filler between the clamp and the pipe or spend the 7 bucks. I usually install new clamps after I have the pipe of 2 or 3 times .

I had the exact same problem after the dealer installed one of mine with the spacer twisted 90 degree. I had two left over hose clamps (from old heat shields) that I cut the screws off of and placed in between the muffler and the HD clamp. This allowed the clamp to squeeze the end of the muffler better onto the head pipe. No more issues.

I have heard of people using a piece of aluminum can to create a shim to help stretched out clamps get a little tighter

If the splits on the muffler lip is at 12 and 6 o'clock, make sure the nut on the clamp is on the inside, FACING DOWN at the 3 o'clock position. I had a similar problem of my right muffler sliding back due to my trying to hide the nut by twisting the clamp in such a way where it was less visible and not giving equal tension.

I unhook my rear shocks and let the bike down on the jack so the rear axle clears the muffler. Exhaust is a pain to remove, especially after 40,000 miles.

Are you talking Motorcycle muffler clamps or some other vehicle exhaust clamps? May want to specify and post in the off topic section.

Or maybe you are confused and not aware this is a motorcycle forum.

Best Regards.
