Exhaust Problem
Re: Exhaust Problem
i think the warranty is 85,000 miles
and something has to cause the catalytic converter to fail usually antifreez , damage , oil ect .....
about 2% are bad out of the box ,
The catalyst itself is most often a precious metal. Platinum is the most active catalyst and is widely used. However, it is not suitable for all applications because of unwanted additional reactions and/or cost. Palladium and rhodium are two other precious metals that are used. Platinum and rhodium are used as a reduction catalyst, while platinum and palladium are used as an oxidization catalyst.
CATALYTIC CONVERTER FAILURES:
If a catalytic converter needs replacing, one of the problems below most likely
contributed to its failure.</B>
Engine Tune-Up Required.
A number of problems could occur to the catalytic converter as the result of an engine that is out of tune. Any time an engine is operating outside proper specifications, unnecessary wear and damage may be caused to the catalytic converter as well as the engine itself. The damage is often the result of an incorrect air/fuel mixture, incorrect timing, or misfiring spark plugs. Any of these conditions could lead to catalytic converter failure or worse.
Excess Fuel Entering Exhaust.
The fuel that powers your vehicle is meant to burn in the combustion chamber only. Any fuel that leaves the combustion chamber unburned will enter the exhaust system and light-off when it reaches the catalytic converter. This can super-heat the converter far above normal operating conditions and cause a meltdown. Possible causes are an incorrect fuel mixture, incorrect timing, corroded spark plugs, a faulty oxygen sensor, sticking float, faulty fuel injector or a malfunctioning check valve.
Oil or Antifreeze Entering Exhaust.
Oil or antifreeze entering the exhaust system can block the air passages by creating a heavy carbon soot that coats the ceramic catalyst. These heavy carbon deposits create two problems. First, the carbon deposits prevent the catalytic converter from reducing harmful emission in the exhaust flow. And second, the carbon deposits clog the pores in the ceramic catalyst and block exhaust flow, increasing backpressure and causing heat and exhaust to back up into the engine compartment. Your engine may actually draw burnt exhaust gasses back into the combustion chamber and dilute the efficiency of the next burn cycle. The result is a loss of power and overheated engine components. Possible causes are worn piston rings, faulty valve seals, failed gaskets or warped engine components.
Deteriorated Spark Plug or Spark Plug Wires.
Spark plugs that don’t fire, or misfire, cause unburned fuel to enter the exhaust system. The unburned fuel ignites inside the converter and could result in a partial or complete meltdown of the ceramic catalyst. Spark plugs and spark plug wires should be checked regularly and replaced if damaged or if wires are worn or cracked.

Re: Exhaust Problem
ALSO
Oxygen Sensor Not Functioning Properly.
An oxygen sensor failure can lead to incorrect readings of exhaust gasses. The faulty sensor can cause a too rich or too lean condition. Too rich and the catalyst can meltdown. Too lean and the converter is unable to convert the hydrocarbons into safe elements and may not pass a state inspection.
Road Damage or Broken Hangers.
The catalyst inside a catalytic converter is made from a lightweight, thin-walled ceramic. It is protected by a dense insulating mat. This mat holds the catalyst in place and provides moderate protection against damage. However, rock or road debris striking the converter, or improper or broken exhaust system support can cause a Catalyst Fracture. Once the ceramic catalyst is fractured, the broken pieces become loose and rattle around and break up into smaller pieces. Flow is interrupted and backpressure in the exhaust system increases. This leads to heat build-up and loss of power. Possible causes of a catalyst fracture are road debris striking the converter, loose or broken hangers, potholes or off-road driving.

Re: Exhaust Problem
Well thanks all for the input. The thing everyone agrees on is the part number for the replacement COMPLETE left exhaust is correct. And the hole thing will be replaced under warranty. Its been 4 days since I called
Chrysler with this problem and am getting no answers. There are 3 Crossfire
Techs at this dealer and there are allways Crossfires there for some kind of
repair. I think this dealer can best handle this better than my home dealer with 1 tech and I never saw another Crossfire there since I purchased my car. Do you think me unreasonable to ask Chrysler to transport my car and
I back to Pa. if they cannot resolve this problem . Or just drive it till it stopps running in the middle of nowhere.

Re: Exhaust Problem
Hi all, Im from the UK and bought my first crossfire a couple of months ago. Last month the engine light came on and I took it to 2 garages for them to tell me what the code was (P0432 Catalyst 2 Efficiency below Threshold Bank 2). I then had to try and speak to Chyrsler directly to find out which side was affected.
Chrysler quoted me £1400 and implied it was the left hand down pipe. I gave this information to the other two local garages and got a quote for £400 and £913!! The £913 garage they were worried as it might not start after the repairs and it might have to go to Chrysler afterwards to have the code re-read and the £400 garage said that they have no concerns as they've dealt with many other Chryslers (I trust this garage as I know the person who owns it).
My car hasnt shown anything wrong with it as far as I know and I wondered if anyone could please offer some advice and tell me am I safe to keep driving it??
Thanks

Re: Exhaust Problem
I've just been told by the dealer that my Check Engine Light is coming on due to the fact that my "Catalytic Converters are Coming Apart". All four Oxygen sensors are triggering the check engine light.
I have a 2004 Crossfire...not the SRT-6.
I'm very interested in what are the so called "stainless steel high flow cat" mentioned here in this thread. Is that some universal catalytic converter that must be welded in. They must still have platinum inside, right???
The dealer told me $3,400 to fix my Crossfire. I live in California where emissions standards are tough and I due for a smoke check next month!
I'm in shock. Can I get by with non-factory cats somehow?

Arent the cats covered by a 10 year 100,000 mile warranty?
Re: Exhaust Problem
I am at unfortunately at 101,000 and some change. :-(
I don't recall the 100, 000 catalytic converter coverage, however.
I guess I should call the Chrysler Rep.
PS: Since posting here last...I've become suspicious of the dealer conclusion that I need to replace the cats. They actually said that is the first step before they determine why all four O2 sensors are reporting error codes.
Sounds backwards. The cats are more expensive than the 02 sensors...even if I replace all of them! Don't understand why they can't diagnose the 02 sensors on a bench or something. At least see if they are working correctly.
In addition. I took the car to an independant (non-Chrysler shop) They say the cats are not "leaking" or "coming apart" as the Chrysler dealer says. They put it in writing as well.
No charge.
Going to a third shop that specializes in exhausts and getting a "pre-test" at smog shop this weekend.
I'll see what those two have to say.
Yikes !

Re: Exhaust Problem
SRT is a a different unit and does not match the picture in the parts book. Jobber cost for a reman unit form the local mercedes dealer is 1250.00 per side that includes pipes and both front and rear cats. And yes they are hard to come by.
When my rears decided to blow like the sands on the beach, I went and searched and wound up at my local muffler shop and sourced two small high flow cats that fit. It is really tight up near the engine with not much wiggle room. If you check the bracket that hangs the exhaust between the rear and front cats there is a MB AMG part number there, it is the same as the slk32.
