I Have a swamp series and Less then happy with the sound...If I Was 80 it would be ok but this thing has no sound to it!!! How can I make this HMF Swamp Series Louder??? take it apart and drill out some holes or what??? Anyone know???

 

Louder is not more power...... that muffler was designed to flow and sound like that, modifying it could adversely change the way it flows and even hurt your power, even if you do make it louder. Ya, you can gut it and sound like a hammer in a garbage can, but if all you want is noise, get a race muffler or and old Supertrapp and leave out the baffle in side. At least now, your riding buddies wont hear you coming until you are roosting them with mud, wouldnt that be more fun???
