i have a set of 4dp pipes for sale, I believe they are early 4dp copies, not OEM pipes, they are very light, well made pipes, not sure who made them and are in very nice condition, they have egt bungs welded to them. They fit my 4tw also, so will fit 4dp and 4tw bikes, but the pipes have a longer header length and smaller belly then an OEM 4tw pipe. When I compared measurements to the OEM pipes on the 92 4dp I had, they were identical, so this leads me to believe they are early 4dp copies. Pictures are to large to post, please email me direct for any pictures needed and or more details. Looking to get $675.00 US for the pipes, this includes shipping cost and PayPal fees, shipping to the US and Canada, anywhere else, we would have to figure out shipping cost. Thanks Rob builtbyplanatgmaildotcom
