Ever Install a muffler without welding it?
This is what I was planning on doing, but thinking some more and reading some more it seems almost necessary to weld it, The clamps don't seem like they would be good enough to get a tight seal on pipes and the adapter. I am going from 1 3/4 to 2". Should I just go ahead and install it with the clamps and see if its good enough, if it's not maybe I could take it to the shop after and have someone weld it. What do you guys think?

Yes, it fell off [:(][:0] and then went and got welded. [^][^]0 -
I have done it with no ill effects, but do not recomend it!
1. If you hit a desent bump it can go bye bye!
2. If you do not get a good seal and such it can cause a valve to burn.0 -
Well, of course, welded is better. Clamps don't do so well applied to metal that has constant cycles of swelling and shrinking from heating up and cooling down. But clamps have served me more than once in temporary exhaust pipe repair.

i helped a buddy install an exhaust sytem using only wingnuts, he did that so when he got to the track he could change it up. We did on a duster, i think it had a 340 in it, something like that. 0 -
get a adapter at the auto parts store then it will fit snug 0 -

[:D]Gee, SubN, didn't you have any bolts and straps to go along with those wingnuts?!![:o)][8D][:D][8D]0 -
[8D]-Clamps work fine if you use the heavy metal core rubber mounts to the frame or strong part of body and --
--from the first connection point ,all joints (connecters) have to be(allways) female part of joint, on the downflow side (aft)--
--Which is why all chrome extensions (tips) are larger than the pipe--

As I stated yesterday, get the adapter, 1-3/4" ID to 2" OD. As far as it needing to be welded, it wasn't until all the quicky exhaust shops turned up in the seventies that exhaust was welded. They do it because it is quicker and cheaper for them. A lot of factory exhaust is still clamped together. Use heavy duty 3/8" diameter muffler clamps, not the cheaper 5/16" diameter ones. Do it with the right adapter and good clamps and hangers and it will be there until the pipe rots off. 0 -
If all else fails before the weld put 2 clamps on, we didn't have a welders so we used clamps and sometimes we use 2 heavy duty clamps.[:D][:D][8] 0 -
swamp_thing is correct, I don't think I saw a system that didn't use clamps until the 70's.
There is nothing wrong with a clamp as long as the pipe and muffler are supported adequately so that they don't bounce around. The pipe will soon rust enough to give you an excellent seal, so you don't need to worry about leaks, and the rust will virtually "weld" the two pieces together. You would need a chisel to take them apart after a relatively short time.[:)]0 -
My muffler and turndown was installed in my driveway with clamps.
Old one was ripped off while mudding/fooling around. This one has taken a beating and is still hanging tight.0 -
If the outside portion of the joint is not slotted, it is often a good idea to cut slots part way down with a hacksaw on the quarters.
This allows the pipe to close down better on the pipe that is inserted in it and makes for a tighter fit.
Just make sure you don't cut down further than the insert pipe goes in, or you will have created a leak right from the start.0 -
i remember when no one welded them, of course this was before catalytic converters, and emissions control, you used to be able to buy every part needed cheap, but why do it now days you can get everything installed for not much more than you can buy the muffler with a guarantee 0 -
Yes - never had the need for welding it.
Have covered both parts in copper-paste, to make it easy to disassemble too.0 -
Go to Auto Zone or equivalent & tell them what you have. Get the adaptor or adaptors if you cant do it in one step.
As you go downstream in an exhaust system, each adaptor should go inside the next pipe; not outside.
Use HD clamps and tighten till you slightly deform the pipe under each ckamp.0 -
Both work equally well.
I prefer to weld. But my main mud goat has had clamps for the past 4 years with no problems.
Did not even leak when the middle DD used it for a ditch digging project she was working on for school.0 -
Believe it or not, JB weld is some pretty bad putty. I've fixed the cracked block on a alice chalmers fork lift with JB weld. You could use it, and it would probally work fine. 0 -

HEY WE HAVE A BINGO!
this is how i have done it since about '68 when i started helping the old man in the garage (2 bays, 3 pumps...i lived there most of the time)
and i have NEVER had a pipe come loose on any of the vehicles until they rusted off0 -
Years ago ,cause we all had kids
and no money.We used tomato soup
cans, a mile of that sticky heat
tape and metal coat hangers which
one kept a good supply of in the trunk!0 -
Mufflers were clamped on for 50-60 years without a freaking problem!!! welding them is fairly recent, twenty years or so!!! 0 -
...Just get it welded. Clamps will work if you seal it REAL well with the liquid weld stuff in a tube, then clamp it. Be careful though and make sure it's sealed well, you dont want the exhaust leaking and seeping up into the cab of your truck...unless you look good with cherry red lips...[;)] 0
