Quick expansion chamber banana exhaust review

[dylanr26]

I recently got a "banana" expansion chamber from ebay for $35. It doesnt have the silencer on it. Anyways its pretty quiet in my opinion, but the sound that does come out is very rich. The second i start up my bike it now pulls like all ****. Big difference from the stock exhaust! Remember these dont improve top end (maybe 1-3mph) just acceleration. I hit 34 mph with a 44t sprocket today weighing 175 lbs 6ft tall and it now pulls up hills like nothing. Enjoy

Yep getting one of these little engines breathing better makes a nice difference in torque on the hills, a stock pipe that is gutted and has had the little stinger pipe removed and the hole drilled larger helps a lot but the little banana pipe does a good job in my opinion also, I have one bike with one of those banana pipes, I cut the end off so it has a larger opening on it also, that made it run even better on the old bike, it is a lot louder now though.
