Toyota - Sienna :: 1999 - Loud Exhaust Noise / Bad Catalytic Convertor?
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.

View 5 RepliesFord Exhaust System :: Exhaust Leak At Manifold Where Donut Gasket Meets The Catalytic Converters
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....
View 3 RepliesFord - Escape :: 2004 - Check Engine Light / Catalytic Convertor Needs To Be Replaced
I own a 2004 Ford Escape, auto, v6. I bought the car in 2007 and have had trouble with my check engine light ever since. It is usually on, but will turn off shortly after I wash it (then back on a week or so later). When mechanics test for the code, they say that my catalytic convertor needs to be replaced. In addition to the on/off strange behavior, I have been driving this car for 4 years now with no major mechanical trouble that I can only assume would result from not replacing the CC. This would be very expensive repair, one I am not interested in doing if this is possibly just an electrical problem. I am ready to get this problem solved and start driving check engine light free.
View 3 RepliesFord Exhaust System :: Catalytic Converter Locations
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.

The engine light on my 2001 Toyota Solara V6 keeps coming on with a code that indicates the Catalytic convertor. The convertor has been replaced 3 times with Mineke non-OEM replacements. The O2 sensor on the muffler has also been replaced.
Question, is there any other repair that can be done to correct this short of Toyota doing a full exhaust replacement?
Ford Exhaust System :: Catalytic Converter Failure - Engine Knocking Under Acceleration
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.

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've got a 2006 6.0 350 with stock exhaust and am wanting to either delete the cat or the muffler, but not both. I'm curious how each would sound? For example, would deleting the cat make it louder than deleting the muffler, or will one make the turbo whine more audible than the other? Also, is there any benefit to deleting one over the other, performance wise? Oh, I'm not really looking for loud and obnoxious, but more turbo whine wouldn't be too bad .

After a couple of setbacks, including forgetting to install 3 out of the 4 orings on the oil cooler, I got the IPR Gen2 delete installed. I have a couple of issues since getting it started. I have low boost, I know the up pipe for the turbo is seated well, really surprised about that. However, the exhaust pipe may have a slight leak, but not positive. Finally, the last on this issue, I have a ripped MAP hose that I'm going to replace.
Next issue is that I hear what almost sounds like a gas engine exhaust rumble from the front of the truck. What it could be? I had white smoke initially coming out of the exhaust, but it cleared up after getting everything up to temp and taking it for a ride down the road. On a side note, the leak that I had from my previous thread seems to be gone now.
Ford Super Duty (1999-2016) :: 2003 - Muffler Delete On Stock Exhaust Sound?
How will a muffler delete on stock exhaust sound? I don't want to remove the cat because I don't want it to be too loud. I want it to sound good but not too much whistle (considering my truck is a 2003 the whistle would be very loud) Should I just to a delete pipe on the stock exhaust, or do a cat-back 4 inch straight pipe? what will sound better? Also doing the cat back exhaust will cost a lot more.. but is it worth it? What I should do.

I recently purchased an 04 Excursion XLT with a 6.0. I want to do an EGR delete and install a coolant filter system to address the oil cooler issue. After doing some research I am confused on which coolant filtration system is best. I have looked IPR's setup as well as sinister diesel's system. It seems that IPR's system would filter more coolant however I'm not sure if it is better than the other systems on the market. Are there any other systems that I should look into?

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?

View 2 RepliesFord Exhaust System :: Exhaust Quieter When Cold / Much Louder When Warmed Up
My F150 exhaust seems rather quiet when I first start it up, but after it gets warmed up good, the exhaust is much louder (which I like). I started wondering if I had a crack up front that widened out when it got hot, so looked under it when I got home today with it hot and still idling, but didn't see any cracks. Also I did not hear any noise like a leak. All sound was coming from the side exit pipe. So... what is the phenomenon that would cause this?
