Product Details
RPM Kawasaki H2 Big Mouth E-Valve Pre-muffler Replacement w/ 6" Resonator – Electronic Dump Valve
With many dyno comparisons, changes to tubing size and bends, we've landed here on the perfect OEM muffler replacement with integrated E-Valve. We added a 6" resonator for maximum flow efficiency and the smoothest possible performance, while significantly reducing rasp and unwanted noise from the exhaust tone. A slight increase to 50mm tubing created the ideal exhaust flow balance leading to the factory rear muffler.
This is a true direct replacement for the primary OEM muffler. Instead of a simple straight pipe or crude delete, we engineered a high-flow electronic dump valve followed immediately by an integrated 6" resonator.
When the E-Valve is closed, the resonator knocks down the noise for a quieter, more refined tone. Flip the switch and the valve opens to unleash a loud, aggressive roar with even stronger power delivery. You get the best of both worlds: serious sound and performance on demand, without the constant rasp or drone of typical deletes.
It mounts using the factory mounting brackets, factory gaskets, and factory hardware. 100% bolt-on with zero cutting, welding, or modifications required. No tuning needed either. It installs exactly like the stock muffler.
Built from high quality stainless steel and precision TIG welded for maximum durability. This design unlocks real performance gains on a stock tune while reducing heat radiation compared to the stock muffler. Add a tune and the gains become even more phenomenal.
We've added a second 18mm O2 bung for easy dyno work or wideband data logging, while keeping the factory O2 sensor location fully intact for normal operation. A muffler-side gasket is included although we recommend replacing the header side gasket at the same time (not required).
