DIY Home Depot Muffler Clamps for $2.50

A week and a half ago my only muffler clamp broke.   I brazed it back together nicely but then a few days later the bolt musta vibrated loose and when I got home everything was gone (clamp and rubber damper).

So, I went and ordered a new set of clamps.   After a week, they arrived....too small..... 
Bah!  I got tired of waiting and decided to make a few clamps even if they are temporary while I find some that fit.

Went to Home Depot and found this.....

1-3/8 in. x 36 in. Zinc Steel Punched Flat Bar with 1/16 in. Thick




The perfect length for my 113mm diameter muffler was 16.5 inches.
I cut it so that there was a hole 1/4 inch from each end to allow the bolt to pass through.
Those dimensions worked out perfect.

After smoothing off any rough edges I bent the last 1 inch,  90 degrees on both ends same direction and then wrapped it around the muffler.






The OEM clamps have a rubber isolater that stinks when the muffler is hot.
My solution is gasket paper.   They sell rolls of high temp gasket paper at the auto parts store.
I haven't done it yet with this clamp but I may go get a sheet and cut strips that will fit inside this clamp
and use a high temp glue to hold them in place.

Best of all....Cost per clamp is only $2.50  
Not bad.   Maybe it'll be permanent?

Cool. Looks nice, Kind of industrial looking

I believe the cushion would be a good idea to keep the vibrations from rubbing a hole in the muffler or the clamps them selves from shearing from the moment.

One thing that may help is to use a fender washer under the bolt on each side. I like to use the stainless variety that has a little too large O.D. I grind off one side to fit the strap bend.

My current muffler strap does not use a rubber gasket, it is metal-to-metal.

The 2-strap muffler attachments seem more desirable than cracked mounts . . and heavy duty replacements are available.
