Default Damaged pitts muffler

If one of the exit tubes on an aluminum pitts muffler comes off, can it be welded back into place?

I was thinking more in the sense of taking it to some place where they do professional welding. Any ideas?

It will be cheaper to buy a new one, than take it to a welder.

any type of jb weld because of where it is and vibration wont hold eventually it will break again,you might find a shop that would do it for cheap.if they charged much over half the cost of a new one i would just go with new.

I had one welded by a friend. You need to see if it would cost more to repair or replace with new. Mine is still good 6 years after the repair.

I'm not a proffessional welder, but I think aluminum is pretty tough to work with. By the time you pay a standard shop rate you could probably buy a new one.

Take it to a rad shop. Hopefully someone will help you out. A couple of minutes is all it would take but the charge just to turn on the welder could make it not worth it. Good luck.

They are pretty easy for a weld shop to take care of and sometime those guys do you a nice favor for small hobby jobs. Another solution is to go to Home Depot and get a package of aluminum welding rods that are used with a propane torch. It looks like silver solder sticks and is ~$5. I have some and used it on a pitts stinger and it is doing great. Just get it really clean. With a little practice you can make it look nice too.

I took it to a welding shop. They charged $5 and welded both tubes back on. It doesn't look pretty but it works and the muffler goes inside the cowl. I also cut half of the length of the tubes and replaced with silicone deflectors so they don't come in contact with the floor again.

Yep, here in Colombia those things tend to be cheap. Don't envy me too much, I have to pay double of what you guys pay for almost everything else!

They look like they will last longer than the original soldering job.

It does work. I don't know if the impact bended the muffler in some way that may compromise performance. I ran the engine today and it seemed to idle OK and the performance at WOT was kinda OK to. The engine has only got 3 tanks through so I can't really tell because break in hasn't finished just yet.

as a welder myself, I have to say that actually is decent for a hend tig weld on that thin of aluminum/

A tip on cleaning aluminum for aluminum soldering and welding USE A STAINLESS STEEL BRUSH and NEVER let the bristles touch anything but aluminum of plastic that it should be kept in.
and do the work within a few minutes or re clean. oxide is faster then you think!

There are some " aluminum welding rods" that use a torch. however they are not as good as TIG welded welds. they are good though, and it helps to have a really roughed surface as they work more with mechanical/chemo bonds to the aluminum and weaving there structure with the oxide prodused, where as the tig will MELT the two together, and the rods from the LHS will melt onto them no into them.

I'm glad to hear so. The bond seems pretty solid and I checked the inside of the tubes to make sure that there hadn't been significant volume loss inside. It appears to be totally unobstructed by the welding job.
