The 800 tripple makes more Horsepower overall, somewhere around 150 if it has tripple pipes, 140 without. The ZR 800 has about 140 HP. It will be a close one, and it may come down to if this Polaris sled is an XCR or Storm. Either way, Arctic Cat has the power-to-weight advantage here, so it's definitely going to be a close race with out without pipes.
