Straightline Performance Y-PIPE for Ski-doo REV GEN4 850 ETEC shows a nice gain in power for a very wide rpm band.
Different runner length, diameter, and no dimples have made gains of 5 hp at Dynotech Research so this isn't a bad spend for a little performance. Infield testing has shown a definite gain from stock so the BS about this not making power is just that ---BS. Customers are reporting better bottom end grunt and a definite gain over stock in a long pull! Available in black painted or silver ceramic, you can pick your preferred poison.
