who really owns a race sled with stock exhuast these days
anyone who's smart. the stock exhaust is purpose-built on those sleds to gain you the most power possible.
aftermarket exhausts don't do much at all except lose weight. it's a known fact.
...oh yeah...
i happen to own a race sled with a stock exhaust. it's an '07 Arctic Cat Sno Pro 600 Factory Mod. it has Speedwerx twin pipes and twin stingers...but they're 100% stock
only 40 of these sleds ever made for 2007
