Installed some FM tophat spacers in the rear. Got the 195/55/15 BFGs mounted and road force balanced. And added another section of Thermo-Tec heat shield barrier.
Plan to wrap the sections of the exhaust before and after the cat in the future. Want to follow in Adam's example and do what I can to reduce/eliminate gas fumes. I've only ever gotten a strong whiff of them after heavy spirited driving. And chances are the check valves are stuck as they've likely never been touched in 184k miles.
