dc 4-1 is better than dc 4-2-1 all through the rev range by just a couple horsepower, dyno proven on a b series engine on a book called "how to build Honda horsepower" (I cant remember the name of the author, but he is a well known Honda dude). he also says for the money, the dcsports give the best performance.

Which DC sport? The 4-1 or 4-2-1? Should I just spend a lil extra money and get a Comptech 4-2-1 header?
