sch 10 is plenty thick. Im building my manifold right now with sch 10 and it will probably wiegh like 30lbs when im done lol. If i could purchase material again for this project I would of probably drop down to regular 1.5" mandrel bent tubing (~.065 wall).

Personally, I would go sch 40 pipe/elbows. The extra material thickness will ensure your manifold retains its strength given all the heat cycles it will go through.

I think you are asking for trouble if you are considering using 1/16" thick tubing. I hope you plan on bracing the manifold in multiple locations.

I'm fairly sure that no other race cars use PIPE for their exhaust manifolds. Some even use thinner than 1/16" tubing...OMG it's gonna fall apart and kill us all! I've done a number of turbo manifolds with 16 gauge stainless and they all hold up just fine.

Interesting. Question, are you bracing your manifolds/turbos? What material are you using? 304 ss? 321 ss? and is that a tubular manifold? I'm curious.
