    61.9 mph is good for a 2003-- be happy If you want to go faster-- x charger (make sure to swap SC gears), 42's, external intercooler, 12/20 solas, 04-05 RXP ecu w/ the FPR from same ski and upgrade pump to the aluminum 04+ version and you will pick up 8+ mph w/ MUCH improved off the line excelleration

    $1500 in parts-- (some used) to beat RXTs by 3+ mph and to out excellerated RXTX's is cheap to me-- I am used to working w/ 951 2 strokes-- 8+ mph gain is ALOT more expensive and will be running on race fuel...

    It's all in your drive line bro, Check all the components as in bellow, carbon ring, hat, then check impeller, wear ring, ect. All those parts are crucial to not cavitating. There are many threads on this. Your exhaust won't improve power that will be noticed, just sounds louder.

    How fast do you think you should be going w/ a stock ski w/ a modified exhaust?
