I was just thinking about it the other day... what if i made a custom exahust for my sled... one pipe off the tuned pipe, then into a dual out 80 series muffler, mounted to the underside of the bulkhead. Now i know that there are flaws with it all, i mean the muffler would need a shield to keep the snow moving under the sled, and the possibility of damage would be HUGE, not to mention the dual pipes on the underside of the running boards. I am aware of the noise laws also, this would be a "race" style set up and just to see if it could be done. What are your opinions on this? what do you think it would sound like... louder, quieter? better performance? worse?
