Fatty Pipe

Does a fatty pipe really add a noticeable difference in power i mean for the money? How many hp do they really add, like to a zilla? It already has a FMF Turbine Core pipe.

i added one on my 250r after taking off the other fmf pipe i had on there that looked like the stock one it was fairly noticible but i also didnt have stock so it would prolly be more if i wen from stock to the fatty
