Video: RIVA Dual Rear Exhaust Kits For Sea-Doo ’18-Up RXT/GTX & ’21-Up RXP-X


Sea-Doo has to walk a fine line when it comes to exhaust systems for performance watercraft. Certainly they don’t want to restrict their 300 ACE engines to the point that they lose horsepower, but on the flip-side, they’re forced to comply with federal noise restrictions and CAFE emissions standards. This, in turn, leaves the factory-equipped 300-horsepower Sea-Doo with a very restrictive – and complicated – exhaust system that frankly, leaves a lot left on the table – especially when it comes to letting that engine roar!

Thankfully, RIVA Racing doesn’t have to comply with any of those rules and now has a very cool Dual Rear Exhaust Kit for all ST3-based RXT and GTX Sea-Doos and the new 2021-and-up RXP-X 300. Truly “uncork” your supercharged Sea-Doo with this beautifully CAD-designed system that includes mandrel-bent aluminum exhaust tubes (with bead-rolled lips) that that have been powder coated to prevent corrosion; large billet aluminum CNC-machined exhaust outlets, an OEM exhaust outlet block-off and high quality silicone couplers.

Not only are you improving engine performance by reducing back pressure and restriction, but you’re also removing the restrictive sound suppression system located between water box and hull exit, letting all of those ponies be heard when you romp on the throttle. If you thought the exhaust note of a single through-hull exhaust, wait until you hear this thing go! (Watch the video below for sure!) Best of all, this kit can be an upgrade for those already equipped with RIVA’s single Rear Exhaust Kit – and every bit of this kit is made in the USA. (note: not compatible with LinQ retractable ski pylon.)
