Spark Classic GP Style slip-on (Universal)
My Monster 400ie already had the OEM mufflers shortered and cored and it was already sounding like its much bigger brothers, but after fitting a pair, (I know, overkill) these Spark's have made an incredible differences to the music of the Duc. For me, it is better with the Db killers IN. It is still real deep and throaty and loud enough without being offensive. GREAT investment, real easy fitting setup. Guaranteed to put a big smile on the dial.
