The Barkers exhaust weighed in at 6 pounds complete with brackets and hardware. The stock exhaust weighed in at 20 pounds complete. This makes the Barkers 14 pounds lighter than the stock exhaust.

Great muffler. Don't think twice about it- you won't find a better deal. Myself and several forum members have bought from Mike. He has good prices and is a great source for performance goodies for our Buells.

I heard one on an 1125 the other day and it was damn loud. Couldn't believe how loud it was! Great sounding pipe !

Just ordered mine - hopefully it will be here before the end of the week so I can ride this weekend!

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 run mine with no quiet core or pillow packing. I'm sure it hurts low end some however it rips at WOT.

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.

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.
