hey i just subscribed to this site and saw this article and i have something thatll blow you away.
i have an atc 125 m stock everything and all i did is cut off the baffle on the exaust pipe to make it louder and i topped my threewheeler out at 45 mph at centerville dragstrip in centerville Arkansas. and i did it in 10 seconds. try cutting your baffle off and see if thatll improve your acceleration and speed and loudness. i know it did for me.

cut the baffle?..gotta try that....but I dont think it'l get any louder then mine..take a look at my pic page..my corbra pipe is so loud..it needs to be repacked...and it acts more like a megaphone on my exaust then a mufler!

 

I know what you mean...my packing is gone!...I passed my buddy last weekend and had the trike rapped up pretty tight and made his ears ring for ten minutes! That is the advantage of being in front!!!!!!

 

yea it is...but..its not good when ur in a neibor hood...its like runing a motor cycle up the street w/ out an exaust...I get cops called all the time...i hate this town! and state!
