Instead of worrying about marketing hype, search the internet for real dyno comparisons. Or you can search for a rolled Nascar car photo, where you can see the stepped exhaust. Understanding the whole concept of keeping the air moving, the concept makes sense.

BTW: When, not if :) the bolts break off that hold the donut, most auto parts stores carry the equivalent of a miniature C-clamps to bolt it back together, so you don't have to drill out the old bolt.

Not too worried about marketing hype, I don't think I can compare my old big block motor home to a nascar, but if you like them and they are doing the job then that's great. Many swear by Banks too. Any headers that I have put on my vehicles have been a improvement whether I bought them from JC Whitney or a local speed shop that sold Hooker, Headman or whatever brand they happened to sell.
