I've serched for days with no luck so here gos - What type of material/tubing are you guys using to build log style turbo exhaust manifolds? I've used sched 40 black pipe fittings on diesel apps but the manifolds I'm seeing on this sight look lighter than that. Any help would be greatly appreciated.

 

We use 304 stainless steel.

 

What thickness of 304 stainless?

 

Come on - there has to be more of you out there using this style of manifold!

 

most guys are using schedule 10

 

Is that around 16-14 gauge?

 

Check out this build, starting at post #106.

 

This is what I build, have sold many of them. It's secd 40 steel pipe and weldels. Holds up quite well.

Secd 10 is .120 wall
Secd 40 is .203 wall

 

Don't forget the stainless ones you used to build.

 

I only made a hand full of those, takes to long and I don't have a plasma to cut things with. Yours is sexy, wish you would use the damn thing
