Thanks for all the advice, guys. The reason I want to temporarily
replace my cat with a "straight" or "test" pipe is that my car, a 1981
Mercedes SL, has been burning oil because it needs a valve job.
I suspect that the clogged cat is also what has been causing the car's
operating temp to rise, particularly in traffic, since the rest of the
cooling system seems to be fine. In fact the radiator & thermostat are
new, the temps sensors seem to be right on the money, the water pump
is not leaking or squeaking, and the fan clutch seems to be engaging
when it should. So, I want to temproarily replace the cat to see if
that does indeed cause the car's operating temp to return to normal
until I can get around to doing the valves.
Once they're done, I'll replace the test pipe with the Magnaflow cat
that I bought a while ago. Does my original question make more sense
now, or am I missing more than I thought I was :-).
Thanks again for the advice and for any additional advice anyone can
give me.
BTW, I located the pipe cutting tool someone suggested I get. I
justneed to make sure it will rotate in the space betweem my exhaust
pipe and floor
