The Walker muffler I installed on my high-performance automotive is worth every penny. Based on my experience driving with it the Quiet Flow Stainless Assembly delivers on its promise of reducing exhaust noise without sacrificing horsepower.The muffler is also a breeze to install, THANKS to its exceptional build quality and an exact fit. The only con I found is its price, which might not be budget-friendly for some. However, if you're looking for a long-lasting, high-performance muffler that won't make your neighbors hate you, this is the product for you!
