I have an exhaust mani with the flange for the external gate, but I want to put a 90 degree elbow on it so that the wastegate sits horizontal and not verticle. I need to know what metal to use for the elbow that will resist the heat from the exhaust. I will be making a run out to a few shops in the next week to pick up a bunch of the little parts like this so that I can get my turbo finished.

thanks

 

pretty much and type of steel will work, mild or stainless just make sure its thick enough

 

what should it be? like 1/8" thick.

 

what is your exhaust mani made out of? is it cast iron?

 

no the mani is pipe steel. butthe mastegate flange has the wg top pointing straight up and the dump pointing out to the front bumper so I wanted to put in an elbow ant reweld the flange so the wg dump points straight down and can be fed into the downpipe.
