    When I got my '79 crew cab years ago, I bought new GM clearance lights and installed them. I kinda sorta remember the roof being stamped like that. Or maybe that was the roof on my old '90 Burb...

    So the Cherry Bomb Glasspacks drone badly?
    Id love that, though hearing protection would be mandatory.

    Do all Turbo Mufflers drone?

    Placement has a lot to do with it.

    Placement, crossovers or lack of are factors. A "true dual" system with the mufflers far from the headers will be worst.

    It's always a good idea, for drone and power, but it adds cost and clutter under the truck, so 6 of one and 1/2 dozen of the other.

    I call bullshit on the whole mess and they prove it for gain and loss it’s all about the same only real difference is sound no one method is any better then the other as far as hp and torque.
