Question about 1992 Mazda 929

1 Answer

Muffler I went to CarX today and was told that I need a new muffler but the only way to replace it is to also replace the catalytic converter. I was quoted almost $900. Is this true and does it really cost this much? This is on a 1992 Mazda 929

Careful. this sounds very high and there are generic cats that any competent (and HONEST) muffler shop can install with a Mazda or generic muffler.
Don't know how labor is in your area but the cat and an adequate muffler together shouldn't cost over ~$200 US. Check with a 'parts' store that doesn't do installation to see what the individual pieces cost 'over the counter.' If you are in the US, check with your local Better Business Bureau website to find an honest shop.

Tip

RECYCLE THAT OLD CATALYTIC CONVERTER


Sooner or later, most cars will need to have one or more catalytic converters replaced. The old converter off your car or truck can be recycled for cash. Some of the older converters are worth enough to pay for having a new one installed. But most people are not aware of how valuable they are, so they let the muffler shop or repair shop keep the old converter. The muffler shop will recycle the old converters for money that should have gone in your pocket. Personally, I think there should be a law that requires the muffler shops to give the old converters to the customer, or have the customer sign a waiver saying they do not wish to keep the old converter. The waiver should state that the converter can be recycled for cash. And if they waive their right to keep the old converter, the muffler shop should be required to reduce the cost of the new replacement converter by a percentage of the value of the old converter.

I was told my 96 intrepid has an exhaust system with two (2) mufflers by an auto shop. i was then told that what they said was a second muffler was in fact the catalytic converter. which is true?


Hello

If you were hot gas leaving the engine you would go through the manifold, into a small pipe, then in to the catalytic converter, down a longer pipe and finally in to a muffler. So, the Cat is closer to the engine and the muffler is closer to the bumper. You only have one muffler on that car I guess is the really simple answer.

I hope that helps you

I just had the van in to midas muffler to repair the muffler system and the mechanic said that I didn,t need the catalytic converter muffler in front of the big muffler and did the repair eliminating the...


I would go back immediately to the mechanic and demand that the catalytic converter be replaced at their expense. The converter is needed for not only the vehicle to run properly, but also to pass state inspection. Some state laws insist that the vehicle have the catalytic converter. Midas should have known better, and I would definitely demand to speak to management or someone in corporate to have this remedied. I hope this helps and good luck.

1993 bravada smells like sulfer when ran also backfires and i know the muffler needs to be replaced


The sulfur smell usually means that your fuel mixture is too rich, and the catalytic converter is reacting with the excess fuel. You'll probably need to replace the catalytic converter along with the muffler, but get the fuel mixture problem fixed before you do that. Else you will ruin the new converter.

My car is loud!!!


If you take it to a muffler shop, like Meineke, they should be able to give you a free inspection and quote. It will PROBABLY be as simple as welding up a small hole in either the catalytic converter or the muffler.

Good luck!

Replace muffler, not the catalytic converter which started to rattle. Stop running, will crank but will not start. can it be the catalytic converter.


if the converter is rattlin then it needs to be replaced because the element inside is broken. if the jeep still does not run try removing the catalytic converter to see if the restriction is too much. should start if the converter is restricted. if it doesnt maybe its whatever caused the converter to go bad in the first place
