🔥 The Ultimate Exhaust Upgrade for Your RXP-X

Ready to give your RXP-X the sound it deserves?
The Worx Rear Exhaust Kit for 2021+ Sea-Doo RXP-X is here to level up your ski’s tone and attitude.

Engineered for performance and built to last, this kit delivers a deep, aggressive exhaust note with a slight bump in performance to match.

✅ Billet Anodised Aluminium Outlet – Built tough, looks clean, and features our signature Worx logo
✅ High-Thread Silicone Hose – Designed to absorb drone and vibration for a smoother, deeper sound
✅ Sleek Rear-End Finish – Subtle yet unmistakably performance-driven
✅ Complete Bolt-On Kit – Everything you need to get your ski sounding grunty, smooth, and ready to turn heads

Whether you're carving buoys or cruising the bay, this is the exhaust your RXP-X was born to run.

Heads up! All aftermarket exhausts (yep, even ours) are significantly louder than stock. 

If you’re keen to turn heads and sound like a total weapon, this is the upgrade for you.

If your idea of fun is peace, quiet, and hearing your own thoughts... stock’s calling. Probably with a cup of chamomile.
