This stuff is exhausting
It's a fair distance from Gwendolyn's exhaust manifold to her two-stage muffler, and along the way are no fewer than three catalytic converters. Somewhere on the far side of 90,000 miles, I had to replace the front tube, where the pre-cat lives, followed shortly thereafter by the center cat, and after handing over my Visa for that second replacement, I ruefully asked the service manager when I could expect the rear unit to fail. He said he'd never seen one of those go bad.
I suppose, though, it's probably a lot like this:
[T]he item to be "fixed" was exhaust (all three catalytic converters) and they could fix it in a couple days, and for the cost of the parts. (plus, I got the good muffler and the OEM parts) So I get someone else to do the labor, and I still get the good parts. Not a spot of rust on the "old" stuff, by the way. I mean, surface rust, but not one thing rusted through.
However, one amortizes this in the expected fashion:
Guess I can't expect that cat to run for 300,000 miles. I expect to drive this for at least another 150,000 miles and at 1500 bucks, that's about a penny a mile.
I'm shooting for 200,000. Maybe I'm insufficiently ambitious. Then again, I drive only about 11,000 miles a year, which means I have a bit less than nine years to go. (And really, I just want to beat the mileage on my old Celica, retired at 194,500 miles.)Posted at 8:53 AM to Driver's Seat
