2005 GXP Catalytic Converter Part Number
Hey guys, had a coil go in my vehicle and it ended up frying my cat. The warranty won't cover it, even though the cat was fried by the failure of a covered part. I am having a hell of a time finding a catalytic converter for our cars. Is it because it is a Northstar and has a caddy engine and cat? Any help would be deeply appreciated!

you can get this one without the risk of an engine light coming on http://performance-curve.com/3goerli...dii608227.aspx
otherwise the OEM one is the full exhaust system that runs around $900 from the down pipe back all one welded unit

I have yet to hear of a 2004 or 2005 owner of a GXP being able to use a universal converter without the CEL coming on and staying on. Muffler shops just are not good enough to install them correctly so that the rear O2 sensor remains at the right measurment from the cat. I've spoken to dealers, techs, and owners of the GXP'* all over the country.....
BTW the whole unit is now down to 690 bucks, but......you'll need to whiggle the dealer down to matching the price of GM Parts Giant..... and then you'll need a truck to get it home or to your muffler guy.... It'* all one piece and includes the mufflers etc.....and it weighs 140lbs on a shipping manifest....
Oh and if the cat is fried you'll problable need all 3 O2 sensors too at 130 dollars a pop......and seeing as how it was a coil you may get away with only 2 O2 sensors, the one in the exhaust of the bad coil, and the after converter one, but if you are doing 2 already you should go ahead and do the third.....
good luck... I'm in the same boat.......

Was wondering whether anyone has looked into the Walker #163389 Cat for Caddy applications 00-05 DeVille DHS, DTS w/4.6 L engine?? The front rectangular flange uses the same gasket as the GXP, but then it would be a matter of dealing with the O2 sensor bung and cutting the pipe to the correct length.
On line price for the Walker is around $250.

Hey guys,
I just replaced my catalytic converter a couple of days ago. I used a MagnaFlow universal converter, part number 54956 from Summit Racing. The part number is MPE-54956 for Summit Racing and it was only $81.63 and the muffler shop only carged me $40.00 to install it. Car runs great without any problems with codes. Hope this helps you guys out.
