RPM Kawasaki H2 Big Mouth Resonated Cat Delete Mid Pipe With E-Valve

RPM Kawasaki H2 Big Mouth E-Valve Pre-muffler Replacement w/ 6" Resonator – Electronic Dump Valve

Transform the tone and performance of your supercharged H2 with the ultimate smart-sound exhaust upgrade! After extensive dyno testing, tubing size variations, and bend adjustments, RPM SXS has engineered the perfect primary OEM muffler replacement. Built around a upgraded 50mm stainless steel tubing profile, this system optimizes exhaust gas velocity leading to the factory rear muffler while dramatically reducing radiant exhaust heat inside the engine bay.

Unlike crude bypass setups or straight-pipe deletes, this system features an integrated electronic E-Valve paired directly with a 6" high-flow performance resonator. With the valve closed, exhaust passes through the 6" resonator to deliver a refined, smooth tone that knocks down harsh rasps and annoying drone. Flip the included dash switch, and the heavy-duty electronic dump valve opens instantly—bypassing restrictions to unleash a deep, aggressive roar and maximum horsepower gains!

Installation is 100% plug-and-play and direct bolt-on. It mounts seamlessly using your factory mounting brackets, stock exhaust gaskets, and original hardware with zero cutting, welding, or ECU tuning required. For tuners and dyno enthusiasts, we’ve even integrated a secondary 18mm wideband O2 bung alongside the factory O2 sensor port for easy data logging!

Features:

• Smart Sound & On-Demand Power: Electronic E-Valve lets you switch instantly between a refined, quiet exhaust tone and an aggressive, wide-open dump pipe.

• Integrated 6" Performance Resonator: Smooths out exhaust pulses and eliminates high-RPM rasp and cabin drone when the valve is closed.

• Upgraded 50mm High-Flow Tubing: Optimized inner diameter increases exhaust velocity to the factory rear muffler for superior power delivery.

• Dual O2 Sensor Bungs: Retains the OEM O2 sensor location while adding a second 18mm wideband O2 bung for dyno tuning and data logging.

• Lowers Engine Bay Heat: Premium stainless construction dissipates radiant exhaust heat far more efficiently than the heavy stock primary muffler.

• 100% Direct Bolt-On Fitment: Reuses factory mounting brackets, gaskets, and hardware with no modifications or ECU tuning required.

• Precision TIG-Welded Stainless Steel: Built to withstand severe heat, high boost pressure, and rugged off-road environments.
