Rossier Can-Am DS450 Dyno Testing Can Am hit a home run with the introduction of the DS450. Comparing all the stock 450 Sport Quads that have been on our dyno, we found the DS to be the absolute horsepower king. This lightweight, good handling sport quad only needs more bottom end grunt to totally dominate this popular class.That's where we come in. Check out the dyno sheet in our exhaust details to see how we beefed up that weak area while also picking up major gains on the top end. If you own one of these screamers, you owe it to yourself to finish what Can Am started: bolt on our pipe and free air kit and never look back!
Note: Fuel injected engines need need fuel mixture adjustments to compensate for increased power levels. The DS is equipped with an auxillary fuel map in the stock computer that is perfect for the addition of our pipe and free air kit. (See our pipe instructions for more information). However, any other mods such as cams, porting, high compression pistons, etc. will require a Dynojet Power Commander or similar unit allowing for re-programming the stock ECU. This will require a session on a chassis dyno with a knowledgable tuner who can dial in your map to match your choice of components.
