I have a 8 -10 foot peice of 1 1/2" id stainless pipe in the garage. can it be used for anything, oh, and the sidewalls are THICK like, 1/4". Can I use this to build a manifold? if not, what could I use? is the prebent stuff in the autoparts stores worth anything?



I also have a big peice of 2 1/2" id stainless, that is polished Thats gonna be intercooler piping.

why wouldnt it?



good luck bending it, you will need a decent welder to get penetration on 1/4" steel too. I don't recommend using it for this purpose personally, get something thinner, easier to work with, and lighter.

1.25" is too small ID main runners. 1/4" wall is over kill also. I made mine out of 304" sch 10 pipe. It has a wall thickness of 1/8 and is cheep. I got the weld els from mcmaster.com for 4-5 bucks a piece and went to the local steel yard and picked up the pipe for cheep also. I made my flanges from 1/2" 304. I'd stick to 1/2 so it won't warp as easy when you weld it.
