Hmmm...The LX has ~108K miles on it and I'm sure the O2 sensors are the originals. I considered replacing them but the comments I had read were to leave them be until they start throwing a code
. Maybe I should consider going ahead and doing them anyway?
As for my exhaust...It is fine except the end which is squished, yet again, due to CM
. But, I seem to be getting slightly better gas mileage since CM08 so I was thinking the extra exhaust restriction was helping
