this is just an idea, i came across some braze rods that had a working temperature of 1600F. would it be suitable for making a manifold? im not sure what EGTs are usually, but 1600F is pretty high

 

1300 F is about operating EGT's.

I'd resign this to the better luck next time, ideas pile.

 

n/a would most likely hold... but i HIGHLY doubt anything within the first few feet of the exhaust

 

would brazing an exhaust system from the firewall back be more suitable of an application?

 

You could hold a muffler on. I wouldn't go anywhere near where a cat converter would sit on your typical exhaust.
Just weld it man. It's not rocket science to get "just an exhaust" to hold together.

 

the main reason why i was asking is that i had a conversation with a welder that often did contract work for the company i work for. he said that brazing anything, if done right, is very very strong. he said that it would work on an exhaust system no problem from the firewall back since the braze usually has a high working temperature, and because of its high strength, its suitable for holding up exhaust components.

isnt brazing similar to oxy-acetelyne welding?

 

no and no

 

lalala LoL!

 

I know I sure as hell wouldn't trust brazing to hold my exhaust on. Just weld it, or get exhaust clamps or something. And no, brazing isn't like any kind of welding - welding actually fuses the metal together, whereas brazing adds another metal, and acts sort of like glue.

 

Brazing is a non fusion type of mechanical bonding where welding is a fusion type bond. You can add filler or atogenously weld (no filler) as is the case with oxy-fuel welding.

With brazing you don't actually melt the two pieces together but rather melt a lower melting temperature material which holds the two pieces of material together. With welding you are actually melting the two metals together.
