Question bout headers

Can't imagine crashing the passenger side on the Headmans but you will need to be careful going over speed bumps with the drivers side since 3 tubes wrap under the center link.

I don't know if they have always been this way but the collectors do not have a welded on flange. The end of the collectorgot a rolled bulge in it that captures the collector flange and the adapter is got a cone shaped end that matches the rolled bulge. they fit together with no need of a gasket and no leak issues, plus it provides for a little more flexability during installation.
