My Rovan Baja 5b, even with the pipe on, makes a racket, so I invested in a silencer. I bolted it on, as per instructions, but in the process of heavy off-road running, it fell off, and kept falling off. I decided that I'd best weld it onto the pipe.

But I couldn't find a welder to do such a job. I decided to use "JB Weld" (that 2-part epoxy). It held for a few months and then the joint began to fail.
I took the silencer off, cleaned the area of the join, and jammed the silencer on once again. And again, I wrapped the join with heat resistant aluminum tape. I then got "SteelStick" (pictured), made a join (pictured), and tapered the join with a file. (Of course the next step is spray paint it black to match the rest of the exhaust.)
Now, to the reason for this post: I know that this will give me a few months before the heat from the pipe causes the joint between silencer and pipe to fail.
What do you guys recommend for a permanent bond short of a traditional weld job?

I live in Loganville. GA. I contacted a few welding establishments, but they were all "huge" companies that would not accommodate welds for small 'hobby projects' like mine. Seems there are no more small, private shops. But I'll continue trying.
 
Just Google weld shops near me and change your search radius to whatever you wanna drive ??‍♂️

I guarantee you there is someone out there willing to make 40$ for 15 minutes of welding
 
Looking at the pic,it looks like there's no support of the rear part of the pipe,so it's it's causing strain on the joint as it bounces around. Maybe you can rig up something to support the pipe towards the end. I'm sure that would help. Possibly to test get some heat shielding wrap and put it around rear part of pipe to cradle the pipe, reducing vibration and harsh landings along having less movement of pipe end which I think is the issue with the breaking-(Too much flexing of joint).
It's worth a shot.
Good Luck?

I already googled "welding shops near." I came up with a couple of private guys. One was out of the business; the other didn't bother to respond. I'll continue trying. Peace.

The easiest way to fix this issue is just to learn to love the noise.
Toss the silencer in the spare parts bin ??

I love the noise. The neighbors might not. If in the end I can't get a "real" welding fix, I'll just run it without the silencer and hope for no conflicts through any "Karens" calling the police.

I NEVER thought of that! Thanks; it's definitely worth a shot. I'll start looking to the possibility of such a configuration. Peace!

Lol...where I am at ,there is a welder on every corner ,don't know where your at ,but you can try other places like a muffler shop ,
body repair an also ornamental iron creative places that do wrought iron fencing an other steel fabrications!...:cool:
 
They make high temp epoxy that will work. Jb weld even makes it I think. Short of welding its your best option. You could buy a small torch and braise it too. Its not hard. The hard part is making it pretty.

Have you tried any local muffler shops or full service gas stations. They usually have welders and they may be willing.
 
Problem is it might cost more to just throw a quick weld on it. Once you start putting Jb and all kinds of nasty stuff on it. It gets into the pores and makes it a nightmare to weld on. Even cleaning it that you think is clean is not. Have had a lot of people bring me aluminum parts to weld after they have put some sort of fixall style patch job. Those always turn into the jobs from hell it seems. If you do find someone who can do it. Inform them what you done with JB weld and the other stuff. That way you might not get a sticker shock when you drop it off after they have tried to fix it. they might be able to do some prep work to it to make it easier or at least they know what to expect on it.
