with a budget build headers are a complete waste of time and money put manifolds on it it they are great under 1,000 Horsepower and I know of a friend who has a 9 second 4,500 lbs truck with them.

Stainless is about twice as much as mild.

just use mild steel its alot harder to mess up, you don't have to back purge, don't have to preheat use special rod and slow cool (if you plan on welding to cast) o and its gonna be alot cheaper. if you ever wanna spend the coin you can always have em sent out and jet hotted.

If you decide on stainless consider 321 or 347. These grades were designed for welding and your welds won't rust when you are finished.

When you weld stainless you use stainless filler rod, usually a grade above what you are welding....304 will never rust. You can weld 304 also. You dont have to back purge it either...unless you plan on making it worthy of using in a hospitol, food processing plant or dairy farm.

This is for the fittings in the link below.....304 SS.
And to the person using schedule 40.....why so thick? Thats like .145" a lot of people use the .065 paper thin tubing. Sch 40 I think is kind of a waste of money, and a lot of extra weight.

Use 308ss to weld 304ss with and if you do any carbon to stainless use 309ss.
