Can I usee copper pipe for exhaust pipe?

[Looking4new]

The typical exhaust gas temperature is 1,000 F. Copper melt point is about 1900 F. Why cant I use copper pipe for exhaust pipe?

Once it gets real hot (towards manifold) it's going to anneal and get very soft, it's already soft to begin with. The vibration from the running engine will more than likely make your joints fail in no time with the heat. Ever wonder why you don't see things restored with copper exhaust? Because it won't hold up well.

Electrical conduit works well & not to heavy lasted over 20 years on my last tractor.

If the exhaust were short,, copper would work, it would be strong enough.

The big concern I would have is safety.
With copper, the outside temp would be close to the inside temp.
With steel, the conductivity is so bad,, the exterior is MUCH cooler.

How badly you are burned by accidental contact has much to do with the rate of heat flow.
Copper has VERY high heat flow,,,

Why not? Give it a try. Copper may be more expensive than steel.

Why would you want to? What are your thoughts on a benefit of using it? I don't see any..

Copper work hardens, if temps aren't causing annealing, vibration might lead to fractures if not fully supported...

I don't have torches/welder or the means to bend steel piping, I can buy short radius copper elbows. That is the reasoning behind it.

Why not buy flexible metal exhaust as sold by most auto parts.
No need for elbows etc and simply use 'U' clamps to attach.
From memory it can be had from 1" thru 2.5" in 1/4 inch increments, might however be 'special order' at some stores.

You can get angled exhaust pipe connectors use band clamps, u clamps or weld up. If you don't have a welder mock everything up mark it take it to a welding shop or muffler shop have them weld it.
