Ok, few details for ya on these initial headers.
They are a step tube design, fully hand tig welded out of t-304 stainless steel and yes, they are back purched to eliminate weld contamination.
These first units will be test fit prior to shipping for a handfull of reasons, notably to make sure the jigs are properly set up, and make sure everything is going to drop in. These will be popped into multiple cars, using both studs and bolts to make sure install wont be a problem regardless of setup.
Any questions please feel free, dyno charts will be up shortly, as well as possibly some teaser pix :p
