I need a pipe for my yfz 450. I am looking for something that is mean and loud. I also wanted it to have good bottom end power. I was looking into HMF bill balance edition ,but i haven't heard much about them. If you could please just tell me what the best pipe would be for my yfz 450! Thanks.

 

Bottom end power comes with a longer header. The FMF PowerBomb and MegaBomb headers get that effect, but without the extra length.

Less Sound = More Ground, so don't go pissing off all your neighbors by running a loud muffler, and making the whole sport look bad. I suggest an FMF Q4 muffler to go with that header!

 

so fmf is the way to go from what i am seeing

 

I meen what about big gun, HMF, white brothers, pro circuit, or yoshimura?

 

Gytr is good i have that on mine and works and sounds great
