So I noticed today while cleaning bike that my jardine muffler was coming apart. There are two ends on it with 3 pop rivets holding it together. On the side closest to headers I saw it was crooked enough for some muffler packing to show. Further inspection 2/3 of the rivets are broken/loose. The inner flange looks to be cracked. I rubbermalleted it back together for now and bent a bracket over one side to hold in place. The bike runs and sounds right. Can I repair or should I buy a new setup? Ill post some pictures later this morning after work. (Message edited by Butthurt on July 21, 2014) | ||

The rivets are coming loose all around it seems | ||

I would PM Dean (d_adams). He would be the guy to give you the most realistic answer. | ||

This is fairly common with aluminum cans, if the rivets just disinterested remove the can repack and drill the next size up and re-pop rivet, make sure you use the proper size hole for your rivets and if they start getting lose fix before they get to this point again.. If the holes elongated and you weld patch them up and have a go with new rivets. If the rivets are too small or are not tight this will occur as the rivets vibrate wearing themselves and the muffler body away. I have used high temp silicone in the holes on some rivets to help reduce this effect. | ||

tap the holes and put socket cap screws in them. | ||

I tried socket cap screws on my old sport bike (Z750S)and found they back completely out due to vibrations. IMO pop rivets are the best fastener for bike exhaust. | ||

Loctite. | ||

Another option is to install nut plates and use fine thread fasteners. Its a bit more work but makes repacking easier and seems to hold up well. | ||

From my experience repairing old supertrapp and muzzy cans, I can confirm that socket cap screws and Loctite is the business. I've got a carbon RT-5 just sitting around if you end up replacing the whole thing. It was way too loud for me and my midnight commute. If you're not interested, I'll post an ad in the appropriate forum. Good luck guy. | ||

On my old race bike I had the same problem. Started putting steel rivets on and solved problem. | ||

 2 of 3 rivets broke through the end cap. Can a patch weld fix the holes? (Message edited by Butthurt on July 22, 2014) | ||

I am sure that could be welded. I would however have the nuts welded in place during the repair. looks to be a little light weight for regular road use. | ||

That's the difference between theirs and mine. Mine are all .065" wall thickness and also 100% 304 stainless steel. That's also why mine weigh about 3-4 lbs more. | ||

check the "packing" does it need to be replaced? put the cap back on...drill new holes (in a different location than the old rivets ="fresh meat") thru the cap and can...use steel rivets...use the correct drill size for the pop rivets you choose. hope this helps | ||

I like your idea Nuts4mc. |
