About WORX Racing Exhausts
WORX Racing exhausts come in two types. A free flow replaces the stock resonator, with no drilling and a quick fit at home. A rear exit kit moves the outlet to the back of the hull and needs drilling, so allow a couple of hours to an afternoon. Both remove the restrictive stock baffle or sound box, which cuts back pressure and improves throttle response, and both give your ski a deeper, more aggressive exhaust note. Every WORX exhaust is louder than stock, and none of them needs a tune.
Frequently Asked Questions
Free flow or rear exit, which is right for me?
A free flow replaces the stock resonator, so there's no drilling and it's a quick job at home. A rear exit kit moves the outlet to the back of the hull for a cleaner look, but it needs drilling and takes a couple of hours to an afternoon. Both are louder than stock. If you ride a 3 seater Spark, go free flow, as the Spark rear exit kits don't fit it.
What's the benefit of an aftermarket exhaust on a jet ski?
A WORX exhaust removes the restrictive stock baffle or sound box, which cuts back pressure and improves throttle response. It also gives your ski a deeper, more aggressive exhaust note.
Will an aftermarket exhaust make my jet ski louder?
Yes, noticeably. Every aftermarket exhaust is louder than stock. WORX exhausts are tuned for a deeper, richer tone rather than chasing maximum volume, so the character of the sound changes as well as the level.
Do I need a tune to run an aftermarket exhaust?
No. Our free flow and rear exit exhausts don't need a tune.
Will water get into the engine through the exhaust?
No more than with the stock exhaust. Our free flow and rear exit exhausts are designed to stop water travelling up the exhaust and into the engine.
