I'm planning on buying piping from jcwhitney or something for making my own i/c piping. I'm also gonna need a downpipe. Can I order the same aluminum piping for a downpipe...or do I need a certain kind of material like stainless steel or something? If I need something like stainless...where can I purchase U-bends or straight pipes to custom make my downpipe? Does anybody know exactly what kind of bends I will need? It will be on a T3 turbo on a 95LS teg.

 

I recommend getting Stainless steel. Get 2 J bends just to make sure you have enough bends to make the turns.

I got mine at Jegs.
