    Description


    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

    Fits:

    • BMW R 1200 GS (from 2010 to 2012)
    • BMW R 1200 GS Adventure (from 2010 to 2013)
    • BMW R 1200 R (from 2011 to 2014)
    • BMW R 1200 RT (from 2010 to 2013)
    • BMW R nine T (from 2014 to 2016. Does not fit 2017)

    It works but…

    Low rating due to price. Over 80 bucks for a small piece of stainless pipe! Wish I would have thought about it longer due to being able to get one cut locally for 25$. Very fast shipping and courteous service though. For that cost it should have included the servo buddy.

    A piece of 52mm od stainless pipe

    You don't get the raised circumference center section as shown in the photo that would help precisely locate the amount of insertion at the header and silencer ends. Other than that it does the job.
    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.

    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.
    Great sound and easy to install. Great quality

    Great product, fits perfectly. I have a R9T with a yoshimura exhaust. Sound awesome. Recommended
    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.
    Fits & sounds awesome

    I feel my bike�s motor more loose. I sounds nice!
