The traveler's pipes are full of small holes and one of the mufflers has had it so I ponied up the big bucks and put in an order at Waldron's a month or so ago. (http://www.waldronsexhaust.com) All stainless. Up here in Maine you don't get much service life out of aluminized steel. They shipped them through Fastenal, who have apparently been sitting on them for a long while. I finally got curious and called Waldrons, Fastenal called me back and they dropped them off the next day. When I put my order in they were backordered on mufflers, some shop makes them for them to order. So one of the mufflers will get shipped UPS at the end of this week. Not sure when I will get around to installing them as I am busy getting ready to move to the big city for grad school in a few weeks, but I am planning to drive the traveler through the fall and winter so I need to get to it soon. Here are the goods: I also picked up a new O2 sensor and bung from Summit Racing.
