Mike,

 

Try McMaster Carr for aluminum solder and flux. I've had only fair success
with their ally solder and it's probably the best stuff around

 

A couple things to keep in mind: solder requires an absolutely clean surface
to adhere and flow properly. Your best bet is unused, no oil ally.

 

If used, you should scub the ally clean everywhere where the solder is to
stick and then use sanding or steel brushing to prep the surfaces followed
by more cleaning. Actually, you should do that for unused ally parts also
just as we do with steel parts. 

 

Remember that the melt temp of regular muffler ally is around 1200F which is
low for even a propane torch so you could melt holes in the stuff if not
careful. The good thing is that ally solder melts at around 900F so you have
a little margin

 

TIG welding is better, stronger and easier to do well. Luckily I have a
friend who has a rig.....
