I recently purchased a muffler for my automotive and decided to go for the Walker Quiet Flow Stainless Muffler. After I put it to the test, I was blown away by both the performance and the sound. It definitely delivers on its promise to reduce noise while improving exhaust flow, and it looks great too .The only downside is that it's a bit pricey, but I think it's worth the investment for anyone who cares about performance and a quiet ride..
