Might as well through our hat in the ring. We have worked with Billet Tech of Floridafor several years to make billet rail for Modern Muscle. We make these rails because they are the only rail to fit the KB super chargers without mods. They a 8an at all ends. There are 2 reasons to replace stock rails, power level and bling. I guess a good power level to start looking at the rails is about 500RWHP. Most the aftermarket rails are pretty nice and allow you to run large cross over lines and fuel return if doing a high HP fuel system.
