    My dad has a '99 Suburban with the 7.4L big block. He is thinking of getting a Flowmaster 70 series...any suggestions? /forums/images/graemlins/truck.gif

    I have Dynomax on mine, 2 1/2" pipe's before and after the muffler's. These muffler's are quiet, almost stock, but still flow like gangbuster's. /forums/images/graemlins/eek.gif
