I found the weight of 1ft. of 4"OD 16 gauge aluminum from burns stainless, which was .95 pounds, but can't find the weight of aluminized steel in the same thickness and OD. Does anybody happen to know what it is? I'm trying to see if the extra cost of the aluminum is worth the weight savings over the aluminized steel for an exhaust

TIA

 

It's fairly significant. I don't know the exact numbers, but aluminized steel and aluminum are vastly different materials.

 

I thought that Aluminized steel was just mild with a thin aluminum coat, so it would weigh the same as mild.

 

you would not use the same thickness aluminized steel would be thinner then steel because of rusting. you are using it for exhaust?

 

IMO, an aluminum exhaust isn't worth it just to cut down on weight. You can shed weight elsewhere, which is technically free!

BTW, what kind of welding setup do you have now?

 

aluminum is basically 1/3 the weight of steel

 

I would like to see an update from the few people that tried aluminum exhausts. My guess is that they cracked to **** after about 6 months.

If you want to go light, just use 20 gauge stainless. You will save 20 pounds with an aluminum exhaust, but like said above, you can save 20 pounds from somewhere else.

 

When you're building a race car, 20lbs is alot!

 

thanks guys....

I've have the same setup as before....180SD, sold the millermatic 135 so I can save up for a 210

If it's a race car, you don't use a full exhaust, and aluminum would melt in any case.

 

Well, I consider a SFWD car a "race" car, and they have to run a full exhaust. And aluminum will not melt, it's been done plenty of times...

 

I just might go aluminum because my cage is mild and that will probably offset the 30-40 pounds over the chromoly vs mild steel

Yes, I consider a SFWD car a race car as well seeing that it's similar to the hotrod class cars back in the good ol' days aside from a little more interior and body panels

 

When i did the 4" aluminum exhaust on Fergusens car, i was able to hold it up in the air and twirl it around like a baton... lol.. i'd definitely run a full aluminum exhaust in a SFWD car. Its worth every pound

lolz, I think Donatello has found a replacement for a wooden bo staff

 

What thickness aluminum do you guys run for aluminum exhaust? Do you just use v-band clamps to attach the aluminum exhaust to the steel downpipe?

Yes he is correct alum is 1/3 the weight of steel .And Magnesium is 1/3 the weight of Alum.
