Review on 🚗 Enhance Your Driving Experience with the Walker Exhaust Quiet-Flow 21481 Muffler! by Ryan Cornelius

The original muffler on my 2011 Chevy Colorado had a small rusty hole and got louder. While I had a bed I put this muffler on in hopes of silencing the truck again. I am very disappointed in this muffler because it is louder than the factory muffler with a hole and a rumble in the cab at about 60mph. Will be replaced if I ever need to raise the bed again.
