Ford Exhaust System :: Catalytic Converter Locations
Jan 26, 2008
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.

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?

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.

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.

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 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....

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.

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.

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?

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....

I have a 2007 Passat turbo wagon and my cat converter got a hole in it the other day. I drove in morning and it was just noisy otherwise fine. My wife took it in afternoon and almost didn't make it home. Could hardly make it up a hill and brakes had to be applied to floor. Anti lock would vibrate but not very responsive to stopping. Was towed to local mechanic next day and he thinks problems are related. Could the computer cause a breakdown of the brakes due to bad exhaust system? He says he can't find ant leaks in brake system. He is waiting for the cat converter to come in to replace and hopes brakes will work again.

4.6L DOHC - My driver's side catalytic converter is making quite a bit of noise during acceleration when the engine is warm. I have no trouble codes, no cel and the truck seems to be running fine in general.
I am exploring repair possibilities. I've talked to two shops - one general repair, one exhaust specialist. Neither gave me any options other than to replace the whole system. That isn't an option. I'm a semi-competent home mechanic and if that's what has to be done I'll just buy the walker system from RA and do it myself.

Looking for a used catalytic converter that is bad ? I want to hollow it out. I have a couple of these trucks so I thought about just hollowing one and swapping it back and forth for smog testing but my luck i will hollow the one that is going to fail next year.

I crawled under the AeroRetard the other day while it was parked and idling to find out where the rattling noise was coming from.
It seems to be coming from the rear catalytic converter.
I was wondering if this is the case, would it also cause a lack of power, as in driving up a steep hill or driving up a steep inclined bridge?

My new truck is running really loud. I got under it and noticed that the catalytic converter is not connected to the tailpipe. What would I need in order to repair it? Is this a common issue with this truck? If I need clamps, what is the proper size, also the size of the proper tailpipe if it's too rusted out.

It is true that, for a supercharged engine is beneficial to have some back pressure in the exhaust? I have a 2007 FX4 whipple supercharged, 5.4L, 3V, no cat, true dual X 2.5 ", I have no tailpipe emissions problems in my country, my problem is the power to the wheels. I install a high flow catalytic converters?.
The Magnaflow 94106 is what many people recommend but in this forum, people from Bear Rivers says he does not meet the high flows, what is the correct part number.
I have a 4.56 ratio 315/70R17 tires and power makes lose significantly?, is this true?. I have a big question, in particular point 1, because I think I lost torque at low rpm and, according to what I read, maybe this escape as free to be affecting the successful performance of the engine.

I wanted to ask a couple questions about this method of adding Lacquer thinner to my gas tank to clean my so called clogged catalytic converters. First off, I have a 2006 F150 5.4 with 90k miles on it and my engine light is on. When I took it to autozone, they said it was just a clogged catalytic converter. Well to be sure, I took it to another autozone, and they said it was an oxygen sensor. I run a lot of ethanol in my truck. My instincts tell me that the catalytic converters are probably clogged because when I mash on the gas it doesn't accelerate as fast as it should being a V8.

ill be replacing my muffler here soon, its rusted out blows smoke out all the rust holes, and so on. gonna replace with a nice flo master. Question is, when is it time to replace the catalytic converter? 15 years old and 93000 miles, it still seems like its in good shape, but could it be getting clogged? just from the sounds of the exhaust the past few months, it almost sounds like the truck is somewhat congested. The power from the engine is kinda week, but that's the engine itself. I have no real problems getting up to speed. my hesitation issues from before turned out to be water in the gas tank. Figured since im down there does it make sense just to bite the bullet and throw a new catalytic converter on?

The wife's 1997 Mountaineer, 5.0 with all the bells and whistles, Every time she stops, wet, dry, snow, any type of surface, the ABS brakes activate just as she comes to a stop. Heavy pressure, light pressure, doesn't matter. She says it sounds like a cow mooo-ing. 138,000 miles. New pads and rotors were installed 40K miles ago (about 3 years ago) she doesn't drive much but the noise is aggravating. No check engine light, or ABS light. Seems to come on when it gets below 10mph consistently. The Engine light comes on occasionally with a catalytic converter fault, replaced the converters but still get the light. I don't think it is related.
