Dude think about it though....They look exactly like MSDS headers. And I know the person that gave his MSDS headers to Weapon R in exchange for pretty much nothing. And what happens they make SS headers from MSDS's hard work and development. It sucks dick period and by the way I see more possibilites in the header department compared to what msds made. It's just sad that all the others are copies.....Why hasn't anyone tried long tube headers again??? Yeah SHM failed on there design but it could be done. I'm done commenting on this subject...and yes I do have MSDS headers.
