Yamaha GP1800 GP1800R 2015+ VXR VXS Rear Exhaust Kit

Product Overview

Designed specifically for 2015 and later Yamaha GP1800, GP1800R, VXR, and VXS wave watercraft, this premium aluminum rear exhaust kit is the ultimate aftermarket upgrade for riders seeking superior performance, a lighter build, enhanced durability, and a more distinctive, aggressive exhaust note. Designed to replace the performance-limiting stock plastic exhaust system, this kit features a free-flowing aluminum design that eliminates unnecessary backpressure, enhances throttle response, and improves overall power delivery on the water, while withstanding the harshest freshwater and saltwater riding conditions.

Precision-engineered for a near-perfect fit with OEM components, this kit requires no complex modifications or custom fabrication. It delivers reliable performance for leisurely cruising, recreational riding, and even moderate performance tuning, making it the top choice for Yamaha jet ski owners looking to upgrade to lightweight, rust-resistant aluminum parts without compromising reliability or durability.

Performance and Sound Upgrades The optimized free-flow exhaust design is engineered to maximize exhaust flow and reduce engine backpressure—a common bottleneck in stock exhaust systems. This aluminum upgrade delivers significant, ride-changing improvements:
​
Faster Acceleration and Throttle Response: Enjoy quicker takeoffs, faster revs, and more responsive throttle, resulting in a more exciting and dynamic riding experience.​

Smoother engine operation: Reduced backpressure eases the strain on the engine, helping to maintain stable power delivery and idle, even during extended periods on the water.

Balanced exhaust note: Produces a deep, powerful, and sporty exhaust note that highlights the character of the Yamaha engine—without generating excessive cabin noise, annoying humming, or overly loud sounds that interfere with everyday riding. ​

Improved Heat Dissipation: Crafted from high-quality aluminum, this design enhances heat dissipation, reduces heat buildup around the engine compartment, protects critical components, and maintains optimal performance in hot weather.

Marine-Grade Aluminum Construction

This rear exhaust kit is constructed entirely from high-strength, corrosion-resistant marine-grade aluminum, specifically selected for harsh marine environments. Unlike factory plastic components that are brittle, prone to cracking, fading, and rapid aging, these aluminum components resist rust, oxidation, sun damage, and wear caused by saltwater, moisture, and constant engine vibration—ensuring years of reliable service with minimal maintenance requirements. The lightweight aluminum construction reduces unnecessary weight at the stern, enhancing handling, maneuverability, and overall stability—especially during sharp turns and high-speed operation. The sturdy aluminum structure also eliminates the loosening and bending commonly associated with plastic exhaust components, while its sleek, low-profile design maintains a clean, OEM-style appearance with a premium metallic finish.
