damn straight it will, its also another one of those rider things too. I love taking out my 96 CR 125 thats been worked over and laying it to the guys sporting brand new thumpers at the track

A pipe and silencer combo will really wake up a two stroke bike and change its power curve signifacantly. Where will you ride mostly? You DEF want to select a pipe and silencer suited for you type of riding. Some are for all ranges of the power band, some hit like bitch on the top end only, some on the bottom and mid rev range. If you are doing the engine how good are the reeds currently in the bike, they make performance reed valves as well.
