Review on Walker 54559 Quiet Flow Stainless Assembly by Gerald Barrett

Perfect fit and made in the USA. So quiet that you can hardly tell if the engines are running or not. Now I can hear jazz while driving on the freeway, which wasn't possible with the previous Chinese-made SS muffler. And no noticeable loss of performance. This is important if you drive a Si hatchback. The previous muffler did not provide adequate back pressure. Like motocross bikes, Honda engines are finely tuned, and a lack of proper back pressure results in a loss of power.
