FMF powercore 4 Muffler.

[Nettles 400ex]

Well im back again with more questions.

I just bought a mint powercore 4 muffler for a very cheap price off of a good friend of mine.

Sounds and looks awesome

What i would like to know is how much horsepower am i going to gain from it after i properly adjust my jets? (doing it tommorow)

Depends, what else do u have done to ur bike?

[Nettles 400ex]

Its all stock.

Maybe 3hp but I really don't know I've never dyno'd anything just guessed.

[chevymanrick]

Yea it should be alittle bit snappier plus it will sound good :)

[Drfat400ex]

I like the sound of FMF. Nice crackle to em.

I agree with you on the sound and all part. I have an old Titanium 4 from fmf but they stopped making them. It has a crack in and there was packing coming out due to the previous owner so i just wrapped it in some time of metal insulating wrap and the clamp is over it. I been told it sounds real good up at the drag races.
