I never said wasn't going to have it tested. All I have been
interested in is how feasible the project would be to do by myself. I
wanted to know my options so when I take it to the shop and if they
say it is clogged I can make an educated decision on whether or not to
have them replace it for me.
As to not getting the direct fit cat, If the direct fit involves more
work ie, removing the manifold, fighting with rusty bolts, welding,
and the universal just involved cutting and clamping and they both
work the same, I don't see the need for the extra work other than to
keep it looking cleaner under the truck. When the muffler needs
replacing, later down the road (the one on it is only a year old) I
don't mind cutting a flange to fit into a coupling as long as it
works, Or just remove the clamp from the rear of the cat and attach
the new pipe.
Look, I'm not trying to start and argument or compare who knows more
and is a better expert. All I wanted to know was how difficult a job
replacing the cat myself would be. It is an almost 20 year old work
truck that I plan on driving into the ground. Honestly if I can patch
in a cat while it may be ugly, if it fixes the problem, is safe and
legal, then I don't really care how it looks. I am no expert but
fitting pipes doesn't seem to be rocket science, it is in a straight
section of the exhaust and if it is simply cut out, attach a coupling
to the pipes, and clamp on the the new cat I don't see the prob.
However say, that the clamps don't really hold or there was another
reason as to why that would not work. A simple, No, I wouldn't
recommend it because there is a lot more involved than it appears, is
all that was necessary.
