catylitic converter question ($800?!?!?!?)

[jeep90]

RE: No Jeep yet!! but

my girlfriend owns a '99 cherokee sport and it is time to replace the cat. converter. So she calls the dealer (first mistake) to get a price on one. They promptly tell her that it will cost her $800, not including labor. She asked them if she could use an aftermarket part instead to save money and they tell her that it would throw engine codes and it wont pass emissions. I was thinking of getting one of those high flow converters since they seem to be very cheap ($60 ricer version). apparently one from anything older than a '99 will not work due to the ecm. Can anyone shed some light on this? Has anyone replaced theirs with an aftermarket?

RE: q and a

get a universal and slap it in there... i've done it a million times... no codes, passed emissions.... don't let them give it to you dry

 

[Bounty__Hunter]

They're BSing pretty good, any converter will work. It's just important that both fore and aft o2 sensors remain installed. www.jcw.com has them for around $60, hiflow Catco brand.

That's why they call them "stealerships".

:lol:

RE: adding to a lift kit

mhmmmm.... i payed two hundred dollars for them to tell me my cold air filter was sitting on a fuel injector wire causing it to short out, they sautered it up and zip tied my air filter away to the side, two hundred dollars...

beach run

a catalytic converter is a catalytic converter is a catalytic converter... remember that

is that the same as a catalytic converter?

thanks guys, that is what i figured but she is really gullible about anything a "mechanic" tells her. She wouldnt let me go buy a universal one until I found out for sure.

Hi,

Catalytic converters shouldn't cost more than a couple hundred dollars at most. Just be sure that the replacement you buy has the correct ports for the oxygen sensors, because you DO need these sensors in place.

That is why I will not buy a new jeep from a dealer, That and the fact that they don't have in new YJ's left out there on any of the lots! hehehehe tug

 

[Snitty]

most vehicles' oxygen sensors are not on the cat conv... they are upstream and downstream on the exhaust pipe... not sure on your particular application... but you can always weld on a bung wherever needed... that is if you have access to a welder

What about the two catalytic converters on the 2000+ XJ's? I want to find a way to hollow them out or is there a header available for my 2001?

I know... I like to run them dirty!!! (shoots bitching flames too)

Tip: When you replace your converter make sure that the 02 sensors are working right and your not buring too rich or you will screw up your new converter. (run your finger up inside of the exhaust tip, when it is cool of course, :lol: and see if you get black soot-like stuff on your finger, that is carbon deposits from unburned gasoline and is an indication of a rich burn)

I am a little worried that your 99 already needs a converter. I was always under the impression that a converter was a lifetime part unless of course for rust, or broken internally. If they "plug up" this is usally a symptom of something else in the engine managment system such as a rich fuel conditon. With a good manual you can check your 02 sensors to see if they are working. Good luck!

Fridge...you outlaw! I am shocked at you.

NOT....... :lol: :lol: :lol: :lol: :lol: :lol: :lol:

A funny thing happened to one of my buddies rigs last year, he had the converter off and he accidentally dropped it (over and over) on the garage floor and then this steel pipe fell into and through it (over and over) and when he went to re-installed it, it sounded better and ran better.
Very weird indeed.............

RE: brake line woes

you're not gonna be hollowing out anything newer than a 95... just doesn't work

 

[XJNick]

Yes,

I think you'll have lots of little problems with the OBD-II computer system if you choose to "accidently" bypass any of the emission control system components.

Of course, I've never understood what removing/hollowing the catalytic converter accomplishes except to provide you with problems down the road (w/ OBD-II) and to show that you are irresponsible with respect to our environment.

Catalytic converters are part of owning and operating an Internal Combustion Engine. If you find find them to be too expensive or inconvenient, you could always switch to an efficient electric drive system... 8)

hmmmm oO(sounds like a marvalous idea) where did you come up with that!

you could always switch to an efficient electric drive system... and go up to 45 miles in between charging :lol: :lol:

OK, lets clear the air.. pun intended :lol:

A 90 model OBD1 can run better without a cat, your probably right about the OBD2, I just have not had and problems with mine thank goodness. However, I still make my point that if the gee wiz sensors and engine managment systems function properly, the cat should last a very long time excluding external damage or corrosion.

And Nick, to make up for my enviornmental infraction, I personally helped recycle over 800 gallons of used motor oil in 2004 in connection with my job, in my community. So BACK OFF!! JK JK JK :lol: :lol: :lol:

I really appreciate everything your doing Nick and your XJ project is an awesome acheivment!

RE: High speed shake

Just to be clear, the range per charge of most Electric Vehicles is NOT low because of motor efficiency. In fact, DC electric motors are around 80% efficient, AC motors can achieve as high as 90% efficiency. Compare this to a typical Internal Combustion Engine which is lucky to achieve 20% efficiency.

The range per charge is instead largly dependent on what battery chemistry is used. Most EVs still use flooded or sealed lead acid batteries because they are inexpensive and readily avaliable. However, using a more advanced chemistry like Nickel Metal Hydride (NiMH) or Lithium Ion (Li-Ion) batteries can easily provide ranges of 70-150+ miles per charge. In some cases, Li-Ion batteries have provided greater than 250 miles per charge. The problem is that they are still pretty expensive in the large battery sizes used in EVs.

Excellent! But it's going to take continued effort on the part of all of us to
keep this place clean :mrgreen:

Thank You. :mrgreen:

P.S. I'm sorry to have dragged this thread off topic.... but I got myself started. There are alot of things about and related to Electric Vehicles (and their relation to the Auto industry) worth discussing as there are still alot of people who have misconceptions or are ignorant about this topic.
