      Comments about Walker Sound Solution Muffler:

      Have dual exhaust on my 78 GMC these fit the space I had along with the pipe sizes. They really are cost effective. However a two year life span is not good. The internals get blown out prior to the outer shell rusting off. Then they get rather loud in the cab. the outer shell vibrates and sounds like a glass pack with no tail pipes.
