Turbo headers.

Mike,
Use 321 stainless for best results and longest life. The best material would be a 600 series Inconel but it is expensive and a true pain in the a$$ to work with. Don't forget to either purge the inside of the tube with argon or use Solar Flux when welding.

Good advice. 

On the flip side if you are trying to get the car on the salt and don't have the means or whatever to build a really nice set of headers throw some together out of mild steel and go for it.  We were in that situation this last year and Hooley did just that.  Will they last forever?  No, but we don't put thousands or even hundreds of miles on these cars.  I told him just build them and chances are we will be changing something anyway in a couple years.  After 6 runs last summer they still look like the day he made them.  Next year hopefully we will be making some high HP runs and we will just have to see how they hold together,
