Is it quiet?Stephen W.Sep 10, 2021
Best Answer:Hi Steve, I'm glad to assist you. I could say in between the stock sound and the little bit aggressive-sounding mufflers. It will be almost as quiet as the original factory-installed muffler. I hope this helps, and if you're interested, you can click on the link below for direct ordering to take advantage of our ongoing sale and limited stocks. Happy shopping. <a href="https://www.carparts.com/muffler/walker/wk18977?can=CPAE1047" target="_blank">https://www.carparts.com/muffler/walker/wk18977?can=CPAE1047</a>
