Title: Exhaust leak at connection. Slip on to header.
Post by Dad0220 on 04/10/18 at 07:38:41

The 2006 boulevard S40 that I recently bought has a Jardine slip on muffler clamed to the header pipe. Whoever installed it didn't use the proper clamp or reducer because it leaks at the connection. can anyone tell me what I need to make it right? I would appreciate it.
Thanks

I had one of those. I made it right by getting an adapter made and putting a Dyna muffler on.
If you're just wanting to stop the leaking, I don't know what you need to do exactly, but the T-clamp is set wrong.
Loosen, slip just to the end of the slots, covering the slots.
Cheap T-clamps aren't your friend.

Thanks, I was thinking about going to a local muffler shop and seeing if they could weld it together. I'm not sure if it's something they'd do because they can't raise it on a lift to work on it.

Yeah, there is a reason mufflers aren't welded on..
If it's backfiring hard, check the header and cylinder connection.
Is that muffler connected to the frame?

The clamp they use on HD mufflers is the widest heavy duty clamp I've used. If you cut 6 slots in the mounting end and use the same process as mounting a Dyna ,it should seal . the trick is to cut a section of a "tin" can that has the ripples in it ,ends cut at a 45 degree angle , and place it between the exhaust pipe end and the muffler ,and clamp tightly . the ripples being crushed act as a series of seals . I've used this method many times with Dyna's and have no leaks, and JOG makes a point the muffler does need to be supported ,if it's allowed to flop around your connection will fail at some point.

Backfires occasionally, so I’ll check header pipe to cylinder head bolts. Tge muffler is bolted on using the same bracket and bolts that held the stock muffler on.

careful checking those header to cylinder bolts/nuts. 1/4 inch ratchet with only finger tips on the handle. Ya don't wanna strip them.

the rippled tin can gasket is the ticket here. Check out the thread on mounting a dyna muffler and use the same technique in your Jardine.

Occasional backfiring is normal.
With a Jardine, it's almost impossible to avoid it.

Thanks for all of the input. I'll be saving an empty (rippled) can or two after I feed the dogs tonight.
I'll probably try it Saturday and I'll post an update.
