As a result of using this product I found that my car now has a quieter and cozier ride.The Walker 22000 Quiet Flow Stainless Muffler is the ultimate solution for anyone tired of the rattling, buzzing sound of old mufflers. The unique design allows for a more efficient airflow, translating to better fuel efficiency and an improved exhaust tone. My only con would be the installation process was a bit tricky, but a quick visit to a mechanic fixed that. Overall, I highly recommend the Walker 22000 Quiet Flow Stainless Muffler to anyone looking for a noise-free driving experience..
