Che.40 elbows?

^^^^ you are right about sch 10 cracking!!! I use sch 40 yes it is thicker and heavy, but it depends on the size of the turbo and the design of the manifold. The top mount manifold you did, you can use sch 10. Where did you buy your 90 degree bends?

Anybody know where I can get the 90 degree bends in Toronto?

There’s a place in Brampton where I got 1 elbow, bad news is it was $3 more than the place in Cambridge, sure dont seem much but on a cheap part it sure it, better pay 5>8 per elbow
