Trying to Eliminate Drone. Need Another Opinion.

Google "1/4 wave exhaust resonator" plenty of BS and ballyhoo along with some useful theory. Added a 26" x2" to my truck a few years back, worked great to take the drone out of the generic turbo 3" single muffler. Eventually I ditched the turbo and resonator tube and switched to a Walker 22636 heavy-duty muffler and a simple turn down under the bed, even better. I don't think the HD Walker will fit under an A-body though.
