i was looking at http://www.mcmaster.com for the 1.5" pipe for my manifold and had a question on which wall thickness to use, they got schedule 10(.109"), schedule 40(.145"), schedule 80(.200"), and schedule 160(.281"). i was leaning towards shedule 40 with the .145" wall thickness. it is 304L ss.

 

40 is what i see lovefab uses........

 

ok .145" sounds good, thanks man

 

anyone else?

 

sch. 40

 

ok, cool two answers is good enough for me, thanks man
