Q4 Stock Comparison

[nwrider259]

is it worth it? did you change the jets?

This is the Q4, not the Powercore so it doesn't need the quiet core in it.

did u put in the quiet core in the fmf

I am going to have it installed on my CRF 450X next week. I heard it on another bike and was quite impressed with the deep tone.

q4's are meant to be quiet. if you want loud, you go for the powercore4. Not only is it louder, but you get more power as well

sounds better has a deeper performance sound and flows alot better than the catted up stock pipe

[coreeman101]

q4 were made no to be loud

[salvationrox88]

i saw on the fmf website that it had 94 decibles but that sounds almost just like the stock exhaust.

[Tibarus]

I'd say the noise is about 3/4 as loud as stock, if not half.

Nice exhaust =3

[Shewuff]

No worries. There's been a lot of controversy with this pipe, and it is well within legal sound limits according to the local PD in the area.
