I paid $290 for the header and downpipe and $150 for the labor. I noticed that my car started pulling to the side when launched in first. It feels like the torque steer I felt on the Mazdaspeed test drive. I'm gonna get it dynoed next week. The whole combo, AEM SRI, header anf Ractive exhaust should add about 20 extra HP to the wheels, but I'll let you know when I get the dyno chart.
Don't even bother posting a dyno run, unless you have a baseline. No one on this site believes anyone anyways. Including their own mothers. Too much skeptimism and not enough appreciation. Except for me and a few others like JoeP and Perfworks. I am glad to see the rise in protege following and constant improvements being made to improve. Good work with the header and downpipe.
The only modification is to move the EGR connector like 4 inches up. As you can see in the pics there is an EGR connector below the coonection but that one was welded shut.
