i would like to build up my own manifold and i think i will chose a log style manifold and would like to get advice for the thikness of the piping also the diameter of it im puting this manifold on a d16y8 then a think that te runer tubing is actually 1¨3/4

sorry for messing english but im trying hard to be understand

 

i built mine with regular exhaust tubing! A nice way to do it is to buy mandrel bent pieces and just cut the bends and wallahh!!

 

2" Schedule 40 weld els from a plumbing supply store.

For a how-to, go here

 

what kind of welder did you guys use for the manifold?

 

same here old sku wire feed but , its got wire, its got heat, it does the job,but its all about the settings

 

I used a tig welder but a mig will do fine.
