stock pipe, no power

2 posts in this topic

I've recently replaced my fmf power core4 with the stock exhaust thinking it would be a little quiter, I was surprised to hear there was little difference in noise, it seemed to ping more like a two stroke rather then deep four stroke. But the power difference was amazing, it felt as if I was on a 250, not a 400. The reason I did this was I think i'm to loud with the fmf to ride on natioinal forest land (96 db?) can anyone tell me what this bikes(wr400) noise level is with stock and fmf power core4 exhaust is? Thank you
