What happened to the mufflers? Did you get any more speed out of the boat with taking them off?
The mufflers I ran, did not impede any HP. The boat only got louder with them off. I just wasnt too big on the looks of them. My buddy runs a very similiar muffler on his buggy and they work great on that application too. I practically gave them away to another board member. DNE supplies these if you would like a set, I highly recommend them over anything else as far as performance goes.
