Prius (2001-03) :: Loud Noise Coming From Exhaust System / Catalytic Converter Replacement
Jul 24, 2012
After hearing some loud noise coming from my exhaust system, it was determined that there is a hole (from rust) in part of the cat. assembly. Three shops advised for replacement, there are no aftermarket products for this unit. I have NOT gotten any error codes, the only problem is the noise. What to do? The car is 10 years old with 86000 miles. I have been reading about some of you getting just the one piece and having it welded on, but I do not believe any of the shops here will do that, and indicated that it would be a very temporary fix.

Long story, I'll try to make this short, 2000 E250 5.4L What would or could happen if the catalytic converter was removed from the exhaust system?

My wife's car is a 2002 Prius, 149 k miles. Lately the check engine light has been coming on. I took it to the dealership, and their assessment is that the catalytic converter needs to be replaced. They are recommending about $2,000 + of repairs. While I am contemplating the practicality of investing that much in keeping this car going I'm wondering if it harmful or dangerous to continue operating this vehicle.

I have a 2001 Ford F250 Diesel. I recently cut the 4 inch exhaust pipe right behind the end of the cab cutting off the muffler and I thought the catalytic converter as well. I was talking to another super duty owner and he said he thought there was another catalytic converter further up in the pipe. Is this true? If so, how far would would I have to cut it to cut it off. Would this make the truck any louder...wouldn't mind if it did.

Yesterday my 1995 Toyota Corolla (which runs well otherwise) started making the loudest rumbling exhaust sound I've ever heard whenever I stepped on the gas pedal. It also felt like it had trouble accelerating when I would try to get going after a stop. I took it to a mechanic right away, who says it needs a new catalytic converter and resonator pipe.
My boyfriend says this is a repair he could do. He has done some car repair and worked with a mechanic before, so I am considering trusting him on that, but I don't know what types of repairs he's done before and I know he has never worked on this model. What would you take into consideration whether or not it would be safe to attempt this repair at home?

What would cause both Cat converters to fail at 20,000 mi.? Mine went out and the back pressure caused the engine to knock under acceleration. Also blew out an injector and plug. Luckily it was under warranty but wonder what could caused it.

The clamp connecting the resonator and the catalytic converter is leaking around the edges. I changed the bolts and tightened the clamp but still leaking.

My exhaust on my 01 was rattling. It was coming from the catalytic converter, I assumed it was the heat shield. Put it up on the lift and lo and behold it was something in the cat that was rattling. I was popping a code for the cat anyways so figured I'd just swap it out. Fast forward to tonight. I get the car back up on the lift and I wiggle the cat but no rattling? I go farther back to the first muffler/resonator now it's rattling. It's not a hanger or a heat shield or metal to metal on the outside, there is obviously something of substantial mass inside of it I can almost feel where it is by wiggling around. I chose to wait and cut the exhaust up a different night because I plan on taking that section out as well now, hoping to get out whatever is rattling. If not I'll just have some spare pipe on hand to replace it.

Car is a 2001 MK4 Jetta with 2.0 Auto Tranny and 120k miles, stock exhaust
A little over a year ago I was getting a cel and the code that was being thrown was a DTC 16804. I changed the cat and both o2 sensors and the light went away for almost a year. The other day I was driving and the light came on again. Scanned the car and its the same 16804 code. I replaced the front o2 sensor thinking it was bank 1 but it didn't solve the problem. I clear the code and it comes back the next day. I'm finding it hard to believe that the cat is bad after only a year. I checked for vacuum leaks, faulty MAF and nothing under the hood looks out of whack. My mission is up next month and the car won't pass with this code.

Okay, my wife has a '99 Toyota Sienna with over 200 k miles. Recently, it has began making a loud exhaust noise. I looked at the exhaust system and cannot see any obvious holes. Also, her check engine light has been on for a while. I checked it and it said misfire in cylinder 5 (can't remember the code). Changed plugs and all, still the light. It also idles very high. There's no rotten egg smell that I can tell, but she does say that it seems like it doesn't have a lot of power when accelerating.

My check engine light has been coming on and off and it seems to show P0420 for catalytic converter. The light stays off for about a week and it'll come on for a day or two and off again.
Wouldn't a failed converter stay failed? Can P0420 be triggered by loose/bad gas caps?

My wife drives a 2001 Suzuki XL7. While she was out, the exhaust heat shield fell off the catalytic converter. My question is does this affect the car's ability to function in any way? Is it still safe to drive? My wife is freaking out over it.

I own a 2000 E 250 Econoline van with 170,000 miles. I've been encountering loss of power on acceleration for months. Terrible gas mileage (8-10 mpg) and just recently, I get that rotten egg smell when I gun it and and travel above 65/70. I can feel heat from under the van when i step out as well. I've been blowing individual coil packs every other month after a long drive with a lot of inclines. It all points to a clogged catalytic converter. This van has 3. A front left and right by the manifolds, and a large one before the muffler. My question is, what causes them to go bad? I want to fix the cause before spend the money on new cats. Ive heard a rich fuel mixture could do it. Are there sensors that need to be changed?

My husband,who is an engineer and has done all of our car maintenance for decades is stumped by our 2000 Mazda MPV. He replaced the catalytic converter and put every thing back together, but the car won't run. Will start, but dies right away. Took off new cat,and runs with that off, but not sure why it won't run with the cat on.

I was told that my 1997 kia Sephia needed a new catalytic converter by a very reliable shop. My car had been stalling out and running very rough. They did replace the distributor cap which seems to have increase the overall performance and that same day i had a smog check and passed with flying colors! Why would I still need to replace my converter if I passed smog. My car has only 36k on it.

My truck just started running really loud when it's cold and the leak goes away when it warms up to operating temperature.I did a little bit of investigating and I have found where the leak is coming from at the end of the exhaust manifold where the donut gasket meets the catalytic converters. It appears that the bolts rotted that hold the system together at the gasket. What should I do to repair this? I don't really want to replace the whole manifold because I know I'll break a stud off in the engine because everything is pretty rusty down there. I even took some pictures of the problem....

I have this rattle coming from underneath the car that's been going on for a while.
The car has 110k miles and the rattle is most prominent when I start the car or accelerate hard or just cruising downhill without gas.
I went to one of the well known shops in the area and they said it's coming from the cat and it needs to be replace and quoted me like $1300 for parts and labor which seemed quite steep to me.
They said it's coming from the inside the cat so it needs to be replaced.
Is this a common issue with our cars? I though maybe something is loose and can be just welded together or something.

I'm getting smoke from the catalytic converter area on my 2001 Subaru Forester. The smoke smells of rubber or oil. I've only noticed it after the car has been driven up a long, steep incline of at least a couple of miles. I've never seen it happen after normal highway driving. The car runs fine, gas mileage is good, CE light is not on, 85K miles, regularly serviced.

Where do I start. I have a 2001 Nissan Sentra. 128,000 miles. In Aug. of last year, the engine detonated, so I had it replaced along with other parts. Shortly after that, I noticed a burning plastic smell coming from the car after driving it for a while. I confirmed that that the smell wasn't coming from a plastic bag. Fast forward to Dec 2011, my check engine light comes on. I go to Autozone, have the code read; it's the dreaded 420 code. I go to have it checked out, was told my cat went bad and probably because of the old engine and that the smell is probably coming from that.
The check engine light went off on Christmas day. Fast forward to last month, the light comes on again and I pony up the cash to have the cat replaced since inspection is coming up in June. Now, I had an engine diagnostic run right before I got the cat replaced and it came up fine. The cat was replaced on 4/20. Everything seemed fine. The burning plastic smell went a way, but lo and behold, it came back this week. I don't know what to do. I did a little search on the net and it seems that burning plastic smell indicates there is something going on with engine and possible misfire.

So this morning (Kind of Cold) I went out site and started my car. I heard some noise under the car and I noticed that the noise bad been coming from the Catalytic Converter area and there was water dripping off of it.
My guess is that it was just warming up and the water was from the cold. Is it normal?
I have a GLX V6 ...

i just bought a cherry bomb glass pack and an exhaust system from summit. I am considering running no catalytic convertor. Anything i should know? I know it wont pass inspection but my truck wont pass right now anyway. I am more concerned with loss of power, or worse gas millage....
