[s-cars] Turbo....anyone have a loaner or one for cheap?

[Joshua Van Tol]

It's not really that unlikely that both cats would fail at the same time.
If the engine is run for a time with a gross misfire, that'll overheat and
melt the cats, destroying them more or less simultaneously.

Usually, plugged cats are accompanied by a "wheezy" sounding exhaust, but
since the URS is so quiet by default, it might be hard to tell.

Regards,
Josh
