    Does anyone know if the Barkers will fit inside the Flexiglass fairing and belly pan?

    Probably not, but here's a reference shot where the flexiglass sits. The pipe pretty much has to line up dead center on the motor, at least up front and then past the first footpeg bolt.

    Thanks for the replies Dean... here and on the other site. How quiet were you able to get an RT-3 with the quiet core? Noise is the only thing holding me back from one of your pipes. Thanks.

    Yes it does provided the pan is trimmed for the exhaust tip. The original Barker was designed using Taylor Knapp's race 1125 with a belly pan and full plastics.

    I heard one on an 1125 the other day and it was damn loud. Couldn't believe how loud it was! Great sounding pipe !
    I run mine with no quiet core or pillow packing. I'm sure it hurts low end some however it rips at WOT.

    1125 Exhaust Shootout results.

    http://www.americansportbike.com/Exhaust_Shootout.html

    HP
    1 137.8 Keda RT-3
    2 137.4 Barkers
    3 137.3 Drummer

    TQ
    1 82.73 Keda RT-1
    2 82.68 Barkers
    3 82.11 Keda RT-3

    Acceleration 60-100MPH in seconds
    1 3.32 Barker
    2 3.405 Drummer
    3 3.427 Barker

    Acceleration 100-140 MPH in seconds
    1 3.352 Barker
    2 3.398 Keda RT-1
    3 3.427 Drummer

    Acceleration 60-140 MPH in seconds
    1 6.678 Barker
    2 6.832 Drummer
    3 6.856 Keda RT-1

    Barker exhaust lead every category in acceleration.

    The Drummer that posted the peak HP numbers is not a production pipe. It is a one off race pipe (why it was included is beyond me). The top four pipes were within .7 HP of each other, dam close. Deans pipes did very well, congrats to him.

    Table 1 Exhaust System Weights
    Exhaust System Muffler Weight (Pounds)
    Buell Stock 1125 21.4

    Jardine 5.9
    FMF 6.0
    Barker 6.4
    D&D 6.9
    KEDA RT-3 8.3
    SS Drummer 10.3
    SS Chambered Drummer 10.3
    KEDA RT-1 11.9
    TorqueHammer 13.9
    CES 14.3

    A 1 pound difference in the lightest four pipes.

    The numbers it produced were slightly skewed also, by +4% I think, which made it appear to have the top hp numbers when in reality it did not. One off or production didn't make much difference, both of mine were original prototypes. I guess you gotta start somewhere.

    Good info on the Barker fitting in the pan, I didn't know that it had already been tested.
