turbo guys in here need help
I used Jegs Universal Exhaust Piping kit. only like 225$, and you get Four U bends, 4 45* bends, 4 90* bends, and four 4' straight sections of pipe.
Mine was aluminized steel (basically the same as Mild Steel) Free shipping too.
Oh, and this was for 2.5" diameter. Good for piping from headers to turbo, and charge pipes. For a downpipe, you'd want 3" +
For other types of piping, Check out Ace Stainless.com or Mandrel-bends.com
Mandrel-bends.com has an Ultimate Builder Kit... For two of their kits, you'd still be spending less than the Jegs kit. Wish i knew that when i ordered my ****.
