    Hi guys, could anyone tell me what benefits I would get from switching from my .81 exhaust housing to a .96.
    My combo consist of a 76mm GTS,331 with Dart block, TW heads, hydraulic roller (224/232-.556/.566), powerglide trans.,. The car will see both street and strip time.Thanks

    a slight loss ogf backpressure which is always good and more top end pull. might lag a couple hundred rpm's more though

    I will try to rig up something to check it. I am running a 3'' dp with 3'' exhaust into a 3'' magnaflow at the rear axle

    Just tap into anywhere in the crossover pipe?

    What type of fitting to use? What kind of line? Just use an Autometer pressure gauge or something else? Will it take the heat?

    A simple tap into the crossover will work.
    Add a 6" nipple to help get rid of the heat.
    Use an aluminum line to feed a pressure gauge
    and compair to boost pressure. 2-1 and more is bad.
