RPM Kawasaki H2 3/4 Exhaust – 2.5" Mid Pipe + Chambered Muffler (Straight or E-Valve)
The RPM Kawasaki H2 3/4 Exhaust System is the perfect balance of performance, sound, and simplicity for your supercharged Kawasaki Teryx H2. Designed through extensive dyno testing and advanced flow simulation, this system delivers real horsepower gains while maintaining a refined, controlled exhaust tone.
Built around a true 2.5" mid pipe and RPM’s in-house engineered Q-Series chambered muffler, this system is optimized for the H2’s unique high-flow exhaust demands. The chambered muffler uses precision internal geometry and mechanical chambers to provide excellent sound control while still supporting 300+ horsepower builds without restriction.
This system bolts directly to the factory header using OEM hardware and includes dual O2 bungs—one for the factory sensor and one M18 bung for wideband tuning and data logging. A plug is included for convenience when the secondary bung is not in use.
Choose between a straight mid-pipe for simplicity or upgrade to the RPM E-Valve mid-pipe for on-demand sound control. With the E-Valve, you can instantly switch between a quiet, refined tone and a loud, aggressive exhaust note at the flip of a switch.
