Not a problem with that train of thought. Do you have the same thought with changing the air filter or oil and filter on yer engine...or do you wait until the engine starts having problems? Having a "clean" air filter on modern cars is just a waste and won't improve yer mileage at all. The modern spin-on oil filters weren't introduced on automotive engines until 1955. Do you clean yer windows periodically or wait until it's completely covered over in dirt/bugs/oil before you replace the windshield?
It only took me about 5 minutes (taking my time) to remove my converter after removing my belly pan and drove it up on my car ramps. Four bolts, two nuts (O2 sensor), and two rubber supports and it was out. I know others might take hours longer...especially if yer in the rust belt.
Would you take the chance on cleaning yer converter and O2 sensors if it saved you money from replacing them if they were in still in good condition? Would you spend $5 to try? I'm guessing you'd be happier at spending $100 or more instead...
