How to Choose

Match the tube outside diameter and material to the rest of your build. 304 stainless is the most common choice for exhaust, 321 stainless handles the extreme heat of turbo manifolds and headers, titanium saves weight, and aluminum is the go-to for intake and intercooler piping. Wall thickness and bend radius matter when you need parts to fit together cleanly.

Common Questions

Do I need to back purge stainless when welding?

Yes. Back purging with argon keeps the inside of the weld from sugaring, which gives you a stronger, cleaner joint.

Can I mix stainless and mild steel?

You can weld them together with the right filler, but the joint can rust over time. For best results keep the system one material.
