hello everyone!i am working on a project sled and i just got a different motor for it .my sled is made from 6 different sleds.collected parts over the last 3 years and now i just installed a 700 wildcat motor and the twin pipes will not fit. so i must build new exhaust for it.what would be better ,twin pipes again or single large volumn pipe?i am running a 151 2inch track.this sled is my all-around sled.any advice would be good.
