Review on 🚗 Enhance Your Driving Experience with Walker Exhaust Quiet-Flow 21576 Muffler Assembly by Mike Meyers

The problem is that at idle and with a little gas, a knock can be heard from the muffler. I had high hopes that this muffler would quiet my Chevy 2500 6.0 truck and it helped with freeway rumble but was very unhappy with the rumble at lower rpm. The muffler shop even tried to talk me out of fitting them because they had no luck with them for the 6.0 engines but since I had already bought them I decided against their suggestion to go for it. Never thought it would only be 70 miles, just a commute to work for me. Now I've lost $200 and I'm still unsatisfied with how it sounds, so overall I should have saved myself a lot of headaches and money. Or spend more and get a better muffler. I don't recommend at all
