} As I've said before, DH is a show header. The Tri-Y design was the
} great thing about 20 years ago, since then the header manufactures
} have found that equal length headers are the best. When is the last
} time you have seen a race car with tri-y headers? I've seen them on a
} few old show cars. And besides if it wasn't a show header you could
} get them unchromed. And the last thing a Magnum motor needs is more
} torque, with the intake runners they have torque is a given. Where
} they need help is on the top end past 4500 rpm where they are dead.
} I'll still lay money that if someone runs a set of true duals or a
} cat back with the stock manifolds it will run better then a set of DH.
I don't follow car racing, but I've seen plenty of new 4 cylinder
motorcycles with tri-Y style headers making 200HP/liter at 12-14,000 rpm.
