this is my DD and i already have a set of headers, so im not goin to change to long tubes.
from the links hurst posted, long tubes r the best for torque but lower your top speed/horsepower, un-equal length shorties give less torque but better top speed/horsepower, while equal length shorties r the happy median. which im happy with.
i could have misunderstood it, but thats my understanding. ill let hurst tell me if im right or not

and everytime u google something on this subject, all the info hurst is sayin comes up. so im goin to guess its true
