I have to replace my drivers side primary cat (bank 1) and I'm looking for high flow items, does anyone know if the Magnaflow 99206HM is the right length? I'm going to try and replace the drivers and passengers while I'm in there... Any advice?

 

Why? and I hope you get a little cash for your old cats, 'there's gold in them thar hills', I mean cats. Well platinum and such. If it is split open it possibly can be welded, don't take a mechanics word for it. He just wants the old cats.
They have a recyclable content of rare metals inside. (CLICK)

 

Our old factory cats should bring you $200+ each... Just saying...
They are not aftermarket crap and worth a good penny even used

 

And the local animal shelter keeps putting them down because they don't get adopted...


You all know I'm just kidding right?

 

speaking of used i have all 4 cats with less than 32000 miles on them, for sale ,,,and at less than 200. sale for 199.00 each, or 349.00 for two + 20 shipping , jim

 

In reference to cats, am i correct in saying that when u put the pedal to the floor and it smells like someone busted a$$ in ur car, is that a sign that u need new cats? I get that smell and im running stacked pulleys with fuel pressure originally set to 66psi but kept getting a CEL saying both banks are too rich. Im just wondering if bad cats could give faulty readings and also throw the CEL saying im too rich when i might not really be.

 

I have no cats on my car, 3" exhaust from engine back , no bad smells in my car. I am also running a V8. not the 6

 

I just purchased a 2005 Limited Coupe with 116K miles on it. The only issues that I could find with the car are that the driver's side headlight had condensation in it (fixed thanks to this forum), the hood strut won't hold up the hood, and that there is a check engine light on due to a previous owner removing all of the catalytic converters. I had a diagnostic test run prior to buying, which indicated O2 sensor reading errors validating to me that the check engine was only due to the catalytic converters being removed. I live in a state that does not require emissions testing so this is not a problem other than the check engine light is annoying to look at and the exhaust smell is pretty potent. I have found Direct Fit catalytic converters from CATCO part #s CT-4378 and CT-4379. Does anyone have any experience with these or any other recommendations?

 

I have all 4 catalytic converters from my 05 with 32000 miles on them yes they are for sale make me a offer no less than $400.00 = shipping jim

 

How much are the rear CATS worth? thinking about deleting them on my SRT.

 

I have a pair of PYPES cats for forced induction motors that may go in my exhaust system, not sure how good the mains are. The rears will be removed when I get Rob's headers. I would think a good muffler shop can swap in most cats by adding some length or cutting more out to start with depending on the length of the new cats. When these cats were removed the guy who took them off had moved them way off to the side but I found them. They have less than 2k miles on them. I paid $300. for the pair from Summit or Jegs.

My car's exhaust smells like rotten eggs - Delphi FAQ

My car's exhaus smells like rotten eggs when I start it up in the morning. Why is that ... is usually noticed after a cold start, fast idle, extended periods of idling and full throttle acceleration. ... Replacing the catalytic converter will not eliminate sulfur smell and ... Strong sulfur smell means that you are running a rich air/fuel rat

Running rich can cause the smell and changing the converter will not change that if indeed you are rich. Still trying to dial it in AFR wise? It was tough for me and time consuming as the regulator gets more sensitive as you get a finer tune/AFR. Mark

 

You already stated you were too rich so why would the CEL get thrown saying you were rich so you likely are. How about posting your mods and tell us what the AFR numbers are at? I'm running around 57-58psi at the rail and am using a tune for 450's. Mark
PS: MY AFR's are 11.5 or lower due to this tune that was for 450cc injectors when I was running TORCO.
