'84 muffler tailpipe

Postby flash1942 » Sun Dec 20, 2015 9:59 am



Has anyone ever tried to remove the muffler's tail pipe that looks to be riveted in the muffler? Can it be done? I'm trying to figure out a way to stuff some Monel around that internal pipe that has holes, in order to reduce exhaust noise some.
I know that some suggest stuffing the other end but I'm afraid of creating too much backpressure.

I don't believe they come apart like that, I think the rivets are holding the back plate to the inner assy and then it is placed in the body and the edges crimmped to hold the assy in. Could be wrong but that's what I see.
I am curious about useing monel, it is a high nickel alloy, very tough to machine and used mostly in parts where high corrosion or very low temps are a problem. I worked in and owned a machine shop making food proccessing equipment and I have never seen it used for steel wool because of the cost.

Certainly looks like the rivets are holding it in. Anyway, monel is what jet turbine blades are made of and can tolerate high temps.

well you can try drilling them out, don't know if it will help, still have not figured out how your going to use the monel, are you thinking of wraping the stinger(baffle) tube in sheet monel? stainless will also take the heat and you can get it in wool (spun) form.

Tried drilling out but still only the riveted area appeared to loosen but not the entire piece. I have lots of monel wool and did plan on wrapping the perforated pipe. May be an impossible job too????
I think Honda made the 1200's a little louder because back in the day guys thought the bikes were not loud enough. I do remember that being said in the Honda dealer circles.

I dont know if this will work, but I copied this from another site, basically a home made slide hammer here it is (disclaimer - I have my doubts) - Use threaded rod with a washer just slightly smaller than the exhaust opening and hold the washer in place with nuts tightened securely, pass the washer/threaded rod forward until it drops off inside the baffle then attach a chain to the exposed end of the threaded rod then place a hammer in the chain loop and use this setup as an impact driver to loosen the rust and carbon from the baffle/muffler and the baffle will slowly come out. Worked for me.

Great idea man! I'll see about getting the materials to try it.You said you don't know if it will work but then again you said it worked for you. If it did then was it for the tailpipe?

sorry if I was not clear, my post stopped after my disclaimer. I found the rest of it on another forum and just copied it to give you another idea. It was not me that tried this, I dont have an 84 so I dont know how loud it is, mine is an 86 and to me the thing is very quiet. I thought they were the same exhaust, maybe yours are just burned/rusted out. have you thought about looking for a good used set? I know it's a couple hundred bucks for a good one but when you figure in the work to fix yours....if it works,it might collapse on you, it's not much for the years of service you could get out of it.....just a thought, best of luck if you choose to repair
