I have a 95 honda cr250r. I have been looking around for a new silencer. right now I have a pro circuit pipe and a factory sound 304 silencer. I have been hearing that shorty silencers give more bottom end and a lower tone. Is this true? If it is where can I find a shorty silencer for my bike. I have been having a hard time finding one. Is it possible to cut down my factory 304 silencer to make it a shorty kind of like sport bikes do. also would i have to rejet my bike? Any opinions would be greatly appreciated.
