Does anyone have any knowledge of sidepipe construction? I have a set of sidepipes that are unassembled. The inserts are not in the tubes. Before I install the inserts, I need to know if I should wrop them with something like ceramic or fiberglass. If so, where do I get such material. Any other tips on construction. The pipes are great, but I don't want to put them together incorrectly. Please help!!!
