In your face gangster pipes with aggressive styling and a deep throaty roar. Just the thing for a boulevard brawler. The special steel alloy used in these pipes allows smooth bends and a superior chrome finish. Pipes are stepped design for top performance, 1-3/4" diameter for the first six inches from the heads, then stepped up to 21/4" diameter. Not baffled. Fits Softail® models 1984 thru 2006 and custom applications.
