Catalytic converter replacement

[heygibb]

I intend to replace my catalytic converter and found a suitable source on some previous posts. Here is the link:

My ride has 94k miles on it and I have never changed it out. From the write-up on the description of this direct fit unit, it gives the impression that no welding is needed on the outflow side of the converter. Looking at the one on the vehicle, it looks like the original unit slides into the tailpipe connection to the muffler w/out a weld.

My questions are these:

Has anyone else tackled this on their own?

Can this be done by a layman mechanic w/ rudimentary skills?

I can't weld and don't intend to learn. I don't mind having a muffler shop do the work, but if I can do it myself, I'd rather handle it. I have the means to jack the vehicle up and onto jackstands to get under there.

Thanks for any input.

Welding is not required.

Had one replaced at Midas and they used clamps.

I asked and was advised their is no state law requiring them to be welded.

Thanks Charlie.

If you don't mind, how much did it set you back?

The unit online I am thinking of buying will cost $70 plus shipping. I would do the labor. I'm guessing having Midas or someone similar to do it would cost $2-300.

Sound about right?

I've seen new cats being advertised, installed, for around $150

While on the subject, would it be advisable to go ahead and replace the cat converter.As far as I can determine, mine has never been replaced.

Midas was $315.00 installed on my 1989 Riviera.

Someone has been selling a header pipe with converter attached on Ebay. I don't recall the price but this would be the easiest replacement.

Read this thread:

This cat has the pipe to the manifold, it is the same part number as you stated earlier in your post. I used it on my 89, measure twice and cut once.

[heygibb]

That is the thread where I saw the link to the cat.

juddev, since you have done this procedure, maybe you can give me a few pointers.

Did you disconnect at the manifold from below or from the engine compartment?

Is finding the proper gasket at the manifold difficult, since the cat doesn't come w/ one?

Did you need a guillotine clamp at the outflow to the tailpipe or just jamb it in there?

When you replaced yours, did you replace the complete exhaust system (tailpipe sections and muffler)too?

Thanks for any tips you can provide.

I found a midas muffler shop that put mine on for $50, so I don't have any answers to your questions.

Sorry

[heygibb]

That's cool.

I'll look into that option here. That's pretty reasonable.
