i think it has to do with throttle response shorter = snappier, longer = mellower er.

Shorty's add snap off the bottom and mid range but you can lose a bit of over rev. The longer mufflers usually make the power more linear. As for shortening them yourself it's pretty easy, I used to take about 40mm of my kx 125's.

My muffler (TM300en) has been shortened 100mm to match the mx muffler.
Common mod on the en's.

In back to back testing, I've never been able to tell any difference.

The shorty looks cooler and makes more noise :) makes the throttle response a little snappier

bring back old school,had priced up a mx hgs muffler but at about $300 but shortning looks good will go with the 100mm if its working on ya 3hundy but i might reposition the mount ,saves me having to dick about cutting and rewelding the endcap and can take the excess out of the header end cheers for that.

A  shorty  has  less  back pressure,  with  lower  engine  temps  with  long  motos.  That,s  why  the pro,s   used   short  silencer,s  even  tho  you   loose   some top end  power.
