the pipes were off of a harley sportster and i tied them into the exhaust by extending the exhaust pipe out of the engine to around to the other side. They sound so cool!A harley sportster tank was painted up with spray cans..the handle bars were extended 3". the sissybar was made of some old steel I had around. The weedwacker mtr was taken off and a bigger gocart engine was installed...I put the tractor supply chain guard on with homemade brackets..
