What size of pipe do people use to make their turbo manifold?
And do they use stainless steel? what is the number 409 or 334 stand for in steel?

And for intercooler pipes... what kind of pipe and size?

 

This was just asked about a day ago

 

its tubing.

Most of these manifolds are pipes not tubes.

 

Here is what I got know so far, please correct me if I'm wrong.

Exhaust is 16G SS

And Turbo Manifold is 1.5" shd 10 or 16g pipe/tubes?

 

most manifolds that you see on here are made from 1.5" sch 10 stainless steel pipe and weld els. it works well and will last a long time if its built right.

 

i read somewhere that the difference between pipe and tube is that tubing is acurately measured on the id od and material thicknes and pipe is only measured on (i believe it was) the od and the id and thicknes are not as acurate and can very from pipe to pipe, and everywhere that i have searched for exaust fab materials its all refered to as TUBING but please corect me if i got something backwards.

 

tubing is not cast like pipe and is measured on the OD. Pipe basicly isnt measured at all. The sizes are based roughly off the ID. A sch 10 1.5" piece of pipe is 1.66" ID and 1.9" OD. Most of the pipe I have used is very consistant piece to piece. If you are searching to exhasut parts then yes you are going to find tubing. Thats what exhasut is made out of. Manifolds are too but like I said, most of the manifolds you see here from full-race, lovefab, peak boost, or whoever are made from pipe. You see tube manifolds more on race cars where weight and thermal performance are more imoprtant than durability.
