Looking for just a little more from my '94 XP

[kmartin173]

My friend just bought an SPX with the 657 and right now on smooth water I can raise the trim and inch away from him but I'd like mine to be noticeably faster on top than his. Don't want to do anything major as mine has a new bottom end and runs great, wondering if a different impeller, aftermarket CDI, etc., etc. would do it?

factory pipe but dont know if its for that year. they claim 20 extra hp on stock motor for the 95 xp and 7 mph faster
