Well, it was time. The muffler seemed a bit rusty and I took it to a referred location in North Portland. Master Muffler. Good thing because not only was the muffler and pipes shot, the driveshaft was nearly busted and the front brakes were in need of repair. The front brakes are from a 1985 Jimmy. After 5 days in the shop, all the repairs were done, Don was the best. Despite rusted, broken bolts, unknown parts and a gazillion miles, it was all put back together and runs like a charm.
