Yamaha VX Cruiser HO performance upgrades

I just purchased a 2017 Yamaha VX Cruiser HO 1.8 and am looking to do some performance upgrades. Can anyone help me better understand the performance (additional top-end, acceleration, HP) I can expect out of the following upgrades. I'm also concerned about voiding my warranty. Can you confirm if any of the upgrades below will void my warranty?

1. Riva Rear Exhaust Kit RY15061
2. Riva Free Flow Exhaust Kit RY16060
Whats the difference between the two exhaust kits. I know that one is thru-hull, but is that the only difference? Are there any issues I should be concerned about when adding a thru-hull exhaust?

3. Riva Power Filter Kit RY13062

Besides Maptuning (which will void my warranty), what other upgrades do you recommend to increase performance?

Anything you do that modifies a part of the ski, if it is not a Yamaha approved and installed part, will void the warranty for that system.
Might look into a aftermarket impeller, and intake grate. Just the impeller will be a noticeable difference, and actually should be used in conjunction with any changes to increase hp.
I would use the ski for a bit, get it broken in good, and then decide if you really need the stuff, plus that way you will notice the changes better. I would also stay away from the through hull exhaust. That is strictly a racing setup, and the power difference will probably be minimal, and noise levels will be heavily increased.

Thanks for the feedback. I'll look into aftermarket impellers and intake grates. I'll also check with my dealer to ensure install and warranty is not voided.

I still like the idea of the exhaust, but I'm certain my wife will not.

I also saw your reply to my other post. I followed the break in procedures as listed in the manual. The new manual does not recommend a 10 hour break-in.
-first 5 min idling speed
-30 min below 5,000 rpm
-1 hour below 6,000 rpm
-operate normally
However, I'm aware that I shouldn't ride it hard until after my first oil change.

Any idea how much a new intake and impeller can increase my top speed?

Intake grate will improve hook up, but might shave a bit off the top end. The right impeller will be a all around improvement (bottom and to end). You would prob gain a couple I guess. Impros could probably tell you more, as that is what they do. I can tell you, you will feel the difference.
I'm a believer of breaking in hard, just not over stressing a new engine. Doing a wide open run on a new engine is over stressing in my opinion. You could give full throttle shots, but should stay at 3/4, and do not hold throttle steady. Vary the rpm.
