I have a Turbonetics wastegate. I had to get a stainless steel pipe welded up so that I could re-locate my wastegate because it would hit my hood otherwise. Anyways, the hole diameter from the exhaust manifold is 1.5 inches and the pipe that was used is 2.0 inches (That is all that I could find). The stainless steel pipe is mandrel bent.Could this affect the waste gate operation because of the unequal pipe diameter?

 

Does anyone know????
