Who makes the nicest B series exhaust manifold flange.....and who makes the one(if they still exist) that is the shape of the exhaust port on one side and tapers to the circle type port on the other where you weld the sch 40 pipe to?

we offset the transition to the round pocket for the 1.5" schedule 10 pipe downwards to leave a little more clearance for the top bolts so you can get them in still after welding.

 

Be careful with the mazworx ones. The way they designed it makes it very hard to weld the top of the runner close the bolt hole.It has to be offset down. I bought one and wasn't happy when i recieved it.

 

soo, would sch 10 be ok for a forward facing manifold hanging the turbo out or should i look at sch 40

 

10 is ok Matt

 

I used to use 10 on everything but recently switched to 40 ill never go back super easy to weld and strong as can be... And the extra weight is usefull.
