To say I'm "reved" up about this would be an understatement. Over the past several years I have purchased 5 new Skidoos and always upgraded the exhaust with an exhaust canister from some aftermarket company. For two reasons, 1. I love the noise. 2. A considerable weight savings. This year I took my '02 MXZ700 to a chassis dyno shop to have the clutches tuned in. With the MBRP Trail can in place the engine would rev to 8200 rpms then fall back to 7600. The dyno owner could not figure out why. We tried two different size jets and several clutching adjustments. Finally he asked if I had my stock muffler. I did and we installed it. The motor reved to 8200 and held there. So for the noise and the few pounds of weight savings it cost you HP. Are all aftermarket cans Junk?
