CRF's Only Forums

hello guys,

im new to this site and its my first post.


i just bought a 2003 crf150f and have ALOT of questions..

first question is how quiet is the stock exaust?? the one i bought has a big gun and its etremley loud or my liking.

second question is can i mod the stock exaust to be quieter??


since there's no real legal places to ride around here im going to hit up some schools and factories after hours.

hey, i ahd the same problem with my FMF exhaust just way to loud, so i put back on the stock exhaust and it was better but still loud i would sujjest tryin to put on the stock pipe and see how it works for you, and i think that the stock pipe should be quieter.

on my 06 150 all u can hear with the stock exhaust is the acually engine and the chain. But take the baffle out and u can hear me for kilometers

I'll trade you my stock exhaust for your big gun

Look on Ebay or something similar for a stock exhaust.
My 150F is quiet as can be.

well.......... if you want it quiet.. dont even think about a fmf powercore 4.. im not familiar with the quiet aftermarkets.. so please.. enlighten me....


I need ONe..

I live on a farm and I jump my 150f on my jumps everyday after school. Sound isn't even an issue where i live. Id trade anyone my stock for their aftermarket pipe!!!

I CRF150 is perfect if you dont like alot of noise, its very quite. you barley know its running when its sitting idoling.
