Wich metal material to use?

[matias88e30]

just need info on what would work good and it will last for downpipe/ exhaust tubing?

I have a friend wich works a dock yard as a welder and hes suggesting stainless steel?
what do you guys think?

Stainless would probably work the best. It's also going to cost the most.

You only have two choices really: aluminized steel (cheaper) or stainless. If you can afford it, go stainless.

I don't think they make galvanized exhaust pipe anymore.

316l

Titanium

Inconel.

Just kidding.

Your choices are basically, from cheapest to most expensive, mild steel, aluminized steel, 409 stainless, 304 stainless, and 321 stainless. You live in a reasonably warm area with no snow, so any material should last many many years, so if money is tight, there's no reason not to use aluminized steel.

Ish you Dont want 400 series stainless. 321 is overkill. 304 is iffy. I say 316L is the best. Has to be L so the welds don't crack.

Inco is for heat. If you gonna drop Inco X600 series metal get some hastelloy for everything after the manifold.

You need to have good welds if you want it to hold up. So if you're going to spend the money on stainless, might as well have someone weld it up that knows how to weld.
