    Comments about Walker Quiet-Flow SS Stainless Steel Direct-Fit Muffler:

    My BF's truck was so loud we could barely talk while driving -- not to mention the lovely vibration that I hoped was helping burn calories every time I took a ride with him. This new muffler made such a dramatic difference I always want to ride in his truck and sometimes we just listen to the smooth silence.
