Review on 🚗 Walker Quiet-Flow 21291 Muffler for Exhaust System by Jake Atonyo

were quiet at first. After 100 km it sounds like my consumption is humming at 55. I did a complete exhaust change, I'm disappointed. My suburban 99 family vacationer sounds like a race car. This is the second system I have installed on this truck. The first was a cheap muffler made by Carquest. Much quieter than OEM. I figured the walker would last longer rust free and be quiet. put another walker muffler on, quiet at first, then a few rides, sounds like double glazing
