Hey Guys,

Been lurking here for a couple months, first post. Little history if I may. I ride all sorts of bikes...Harleys, Triumphs, etc. I like to ride bikes that not everyone will see on the road, hence the 09 1125cr I recently picked up. Came with Barker exhaust, K&N, Erik Buell Racing ECM, '10 brake light, axle sliders, upgraded wireharness, stator, couple months left on factory warranty.

OK, Ok, on to my question. The Barker exhaust is loud...louder than my Harley with open exhaust! Also noticed that the CR had a little stumble when riding around town, but fine at upper RPM's. I ordered/installed the 1" quiet core for the Barker, now no more stumble, little quieter, motor runs much smoother/cleaner now. Does Erik Buell Racing tune the ECM/Barker exhaust with a quiet core installed, or tune with the open Barker exhaust? Thanks, Greg
