Cutting A Cat Out

Cutting A Cat Out

Could anybody tell me how difficult it would be to cut a severely
clogged cat that's also rattling out of of a 2" exhaust system using a
hand-held utility saw with a metal blade, assuming there's enough room
to operate?

And if that's not to difficult, I'd also like to know how difficult it
would be to temporarily clamp a piece of pipe into the space where the
cat was unti I can have someone weld a new cat in.

Thanks very much in advance

If you have room to work, a hacksaw will do the job.
a "hand held utility saw" could mean a lot of things, and some of them
would probably be pretty tiresome.

I'd use an exhaust pipe cutter. They are inexpensive and have 4 sharp
wheels that cut the pipe with a 90 deg. rotation.
While you're at the auto supplyb store getting this, ask them if they
have the clamp-on sleeves that are usually used to cover exhaust pipe
holes.

If you mean a Saw-Z-All, it'll be out in a heartbeat..... (
watch your eyes).. Then go to J.C.Whitney and see if they
still sell those "Catalytic Converter test pipes".... These
were short pieces if exhaust pipe, to do exactly what you
are intending, only made to order...

With a Sawzall, takes about 30 seconds.

Why not just get a direct fit cat installed anyway since you're gonna
buy one. One size fits all cats are nothing but trouble down the road.

Make sure you determine and correct the cause of the plugged cat before
you toast the new one.

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

Seems reasonable that a car that is 27 years old and has been aspirating oil
would have a dead catalytic converter.

As others have said, a Sawzall (reciprocating saw) is quick and will work in
pretty tight places. IMO, that is the first choice if you have the option.

And if you are in a state that doesnt go ballistic over exhaust smoke, you
can
drive it a while before the noose draws around your neck. (Here in Texas we
have an on-line reporting system to use to report offenders. And we are
more
tolerant than, f.eks., California.

I would try to stay within plausible deniability of this being a short term
diagnostic
situation only ;>) Even so, if you get caught, you might have some
'splainin' to do.

Do you plan to get the valves fixed about the same time?

Buy a new one and throw it in the trunk. If you get pulled over, you
just point out that you are going to put it in "this weekend". Just
don't get caught again 3 months later.

How did your cat get into the exhaust system? Did it chase a mouse in
there?

Cats usually get clogged with hairballs. Just leave it alone and it will
cough it up.

well no wonder it went up the exhaust pipe, if it was rattling it
probably just followed the rat.

Re: Cutting A Cat Out

Be glad its only a cat. Hopefully the cat wasn't someones pet cat. My
dad hit a skunk once and it lodged in the frame, it stunk for weeks.
Have you tried a power washer? Maybe you can blast it out.
