I just left my favorite Minnesota bike shop. They have a YZ400/426 White Bros. Titanium/Carbon Fibre E-Series pipe for sale. They told me dealer cost. He wasn't sure about the exact price, but around $450.00. They're # is 763-689-2760, www.larsonscycle.com. You can tell them Kevin from New Hampshire gave you the heads up. I asked about a commision and they laughed. But I will get some satisfaction I gave a buddy a good deal.
