Topic: Catylitic convertor question??

[dan684]

i think my catalitic convertor is stopped up.  i was driving down the road and all of a sudden my exaust got real quiet and now if i step down on the gas hard it sounds like it is flooding out.  does this sound like a stopped up convertor and if so what are the effects of removing it and using only a muffler?  i live in horn lake Mississippi so inspection consists of making sure the tail pipe isnt dragging the ground and all 4 tires hold air somewhat.

Yes the cat is clogged up and probably getting very hot. If you dont need to replace it you can just knock the guts out of it or install a peice of pipe in it's place. A cats only function is to reburn unburnt fuel vapors before the go out the tailpipe. A new cat will run about $80 at most muffler shops.

If you knock the stuff out besure to wear a mask.  That stuff is toxic!  I'd just swap it out for a bolt-in.  You won't see any gains in power without it.  Some people have seen a drop too.

My experience with a plugged converter, the jeep would run worse as it warmed up and the material/clog in the converter heated and expanded.  It would eventually kill the engine, then run again after the converter cooled off.

An IR thermometer would confirm the clog.

And a power drill will fix the clog

lol.. git r done

If a drill of adequate size is not avaialable...... use a piece of rebar and a sledge hammer and pound it out. It's messy but it gets the job done. Oh, and as mentioned previously... use a mask. It can be a messy job and you don't want any of the catalysts in your system. :wink:

I had a cat go bad and the guts went into my muffler and clogged it too.

well i took it to my buddy at the muffler shop and he cut a hole in the cat with a torch and cleaned it out. then he welded a new piece of metal over the hole.  seemed simple enough that i could have done it but i dont have a welder handy.

I laugh everytime someone talks about a catalytic converter. One of the guys who works for me fancies himself to be a real good shadetree mechanic. I have heard him on several occassions refer to it as the "cadillac converter". The funny thing is - that is what he thinks it's called. No one has ever corrected him, we just laugh when he says it.

Ask him if he's got the El Dorado model?

Well I called up MagnaFlow (that's the one your using, right Jeffy?)...  I'm expecting one from them on Monday or Tuesday...

I think I've gotta call Gibson and see about replacing the muffler too.  I hear tinging coming from it, so I'm fairly sure it's all busted up inside there.  I wonder if a failed cat will take out a muffler too...   :roll:

I drove my Jeep around all day today (unregistered). The weather is changing and I'm not going to have much time left with the top off.  It's been sitting for a month or two since the registation issue.

The company was called Carsound which is a division of Magnaflow.  A broken cat wil send crap into the muffler.  You might see if you can clear it out without having to replace everything.

The box does say that the Magnaflow cat is a division of carsounds...

I called Gibson today but had to leave a voice mail message.  The logical thing to do is to replace both...  My Gibson system isn't stainless, so I have to see if they'll warranty my aluminized steel one.  That or see what it'll cost me to get a replacement.  They're great regarding warranty, so maybe an upgrade to S/S is in order...

Hmm, I thougth it was the other way around.  Probably the exact same thing though.  I'va had no problems with mine.  Passes CA SMOG with no problems.
