I have Bike Barry's custom exhaust pipe on my Schwinn OCC. From the start it was very loud just as he advertises. Next I installed one pads worth of stretched out coarse steel wool inside the pipe, followed by Barry's exhaust pipe baffle. This combination gave me the sound like the stock exhaust, only slightly louder. Plus my new engine runs smoother than before. My compliments to the look that this pipe gives to the bike!
