So there really is only a negligible difference between the stock Arrow with spark arrestor and the FMF with spark arrestor? If so, why make the change? It was my understanding that the factory Arrow exhaust with sparky was designed to meet the 96 db limit at appropriate rpm which your testing confirms.
