250 SX FMF Gnarly pipe sound test
Got back to 2strokes after having a test on my brothers kx 250.
Installed an FMF gnarly pipe and shorty silencer,really nice power
Sound is nice and not too loud,short clip at the end was filmed with a
phone and it makes the bike sound louder than it is.

1994 YZ 250 Wins a drag race against a 2007 YFZ 450.
Yfz 450 mods: hmf full Exhaust...header and silencer, airbox lid, and
cotton K&n style filter. 180 lb rider.

core 2 silencer. 310 lb rider
Both machines have stock bore, stroke, and engine internals, aside from a
wiseco piston in the yz 250.
In case it's difficult to see what happens because of the lack of zoom, the
quad jumps a full length off of the line and from there on the bike pulls
away hard (even with a rider over 100 lbs heavier). the bike let off at the
end hundreds of feet from where the camera is because they were both topped
out and the bike rider wanted to give the camera some sign language..If you
listen to the sound of the bike, it let off LONG before it got to the
camera..only then did the quad catch up and pass
