After 400 miles running the stock pipe I tried out the fmf gnarly. Ran an hour and a half hairscramble and here is my opinion. Bike was jetted near perfect with stock pipe. Of idle the bike feels more responsive. I had no complaints before but now I believe it's better. I purposely rode a gear higher than I typically would have just to see how this pipe worked. It pulled great riding this way, so much so that I turned the map switch down. I can't say it pulled quite as hard on top but I'm ok with that. I can't tell any difference in sound. For anyone on the fence about trying this pipe and who rides single track, I'd say you will like the pipe. Just my 2 cents.
