    Flapper Eliminator

    Many of the new bikes are outfitted with a flapper valve in the exhaust system. The flapper valve is a device that is intended to reduce noise emissions and it is also claimed that torque output is increased but our testing has shown that this is not necessarily the case. By installing our flapper eliminator, the valve is removed and the motor can breathe freely in all RPM ranges. Exhaust sound is increased but not to obnoxious levels. The engine will benefit from full performance potential throughout the entire RPM range, as with the sound. This part is intended for sport use only.

    The facts:

    • Powerful sound
    • Full power potential throughout
    • High grade stainless steel
    • Easy to install
    • Supplied with everything needed to install
    • Optically discreet, hardly noticeable

    Looks better than the picture
    It doesn’t have that center ring, but it looks even cleaner than the one pictured as a result. Quality section of stainless. Had the bike dyno’d after and while there was no peak power gain, there was quite the bump in the low end! Bike also sounds SIGNIFICANTLY better without the flapper.

    Expensive but worth it. Now I am fine with cat and rest of stock exhaust. Woke the bike up and sounds way better.

    Fits & sounds awesome
    I feel my bikes motor more loose. I sounds nice!

    Does what it is supposed to do
    Nice item, fits well, lots of $$ for a piece of pipe but was worth it for me to get rid of that ugly flapper.

    Great sound and easy to install. Great quality
    Great product, fits perfectly. I have a R9T with a yoshimura exhaust. Sound awesome. Recommended

    I agree with the description, however I did get a power increase when installed with the Remus Headers, exhaust, and a Booster Plug. I do not know if the flapper eliminator had anything to do with the power increase, but I love the whole setup and if you are doing this, you might as well get rid of the flapper too.
