quick question im a Iron worker and in the building that im working in there's a **** load of electrical Conduit pipe in different sizes, i was wondering have any body tried to use this stuff for making an exhaust or down pipe? The only flaw that i saw on the pipes was that they were covered in galvanize. Is there a weight difference between conduit pipe and say ms, ss? please some one let me know cause my buddy can get me a 6' pipe in any size i want, they even have a 6'' piece lol

 

Exhaust pipe is tubing, Conduit is tubing, same stuff really as normal exhaust pipe just a slightly lighter gage some times.
Just grab a chunk measure the OD if its called/ labeled 2" and measure the same as its sized its tubing.
If its not the same size as its labeled its pipe. As an example 3 " pipe is really 3 3/8" to 3 1/2" OD ruffly pipe is nominal size up to 13" , 14 " and up its sized the same its OD.

 

bump for more info

 

what he was trying to say is that tubing is measured as OD, so 3" tubing has a 3" OD. mild tubing is normally 1020

piping on the other hand is measured ID, and has thicker walls, and is made from 1018 mild normally. so 3" pipe is 3" ID, so the OD is bigger.

16ga. tubing, normal exhaust stuff, is .065", or 1/16th"

you need to measure the OD of what you have and the wall thickness of it.
report back here with your findings.
