Riva Racing Dual Rear Exhaust Kit for Sea-Doo RXT & GTX (2018+) - RS15120-D
This dual rear exhaust kit is made for late-model Sea-Doo GTX, RXT-X, and Wake Pro platforms that need less exhaust restriction and a cleaner rear outlet setup. It is designed to reduce back pressure, improve throttle response, and add a deeper rear exhaust tone compared to the stock system. The system uses mandrel-bent aluminum tubing with a powder-coated finish for strength and corrosion resistance in marine use. Installation requires drilling the hull for dual rear exhaust outlets, and instructions are included. Does not fit models not listed below.

➕ Performance Benefits 🔽
- Reduced back pressure: Frees up the exhaust path so the engine can move exhaust gases more efficiently than the restrictive stock setup.
- Better throttle response: The freer-flowing rear exhaust layout helps the ski respond more cleanly when you get back into the throttle.
- Deeper exhaust tone: Adds a more aggressive sound at the rear of the ski compared to the stock exhaust layout.
