Exhaust material

Does any one know whether you could use aluminum tubing for an exhaust? I don't have any exoertise in this area, some people would argue that I don't have any expertise in any area, so any info from some of you smart dudes would be welcome.

Re: Exhaust material

i feel like that materiel would expand and contract too much to be of any use as an exhaust.. or would cool the exhaust fumes too much? at first glance it does seem like a great idea....

Re: Exhaust material

I believe you may want to use the stainless steel tubing. Exhaust causes moisture inside the tubing.

Re: Exhaust material

Aluminum melts at too low of a temperature to be used as and exhaust.

Re: Exhaust material

For Burns Stainless' full dissertation on why they don't build aluminum exhausts. That blue line really sums it up though. That's the yield strength of aluminum plunging as temperatures approach those we'll see in an exhaust system. The purple line on the bottom is the yield strength of annealned 6061-0 that you'll find around all your welds. Yikes!
