yep its for bikes, if you have a Books-A-Million or B&N local try to find the book "Sportbike Performance Handbook" and read the exhaust section
there is some good info in there

 

Consider some of these 'jet-hot' type coatings to keep your baby shiny when you want to show it off.

 

Thanks guys, and agree to disagree works for me. I was going to go back there today but I had other running around to do. I was going to make the same bends as the stock manifold but i may try to get my hands on a Akrapovic hydroformed stainless steel header and look at that... they can duplicate it if i could bring it to them. Im gonna do some more research.

 

Shoot me a pm I can send you a header to model it after. I am here in washington state too.
