Uh oh, cat failure...

Post by Water Hound » Wed Nov 13, 2019 10:30 pm

So my 2004 C2 cabriolet has a self destructing catalytic converter on the driver's side. Rattling like crazy and throwing a check engine light and cat failure code. O2 sensors are fine and it's cat failure for sure. The car just passed 125,000 mi. Exhaust is basically stock other than Gundo hack. Suggestions for replacements? Porsche dealer wants waaaay too much $ for this and indie has nothing special to offer. Saw a big range online from super low no name at $150 up to Magnaflow CA compliant cat at around $625 US ea plus install. Car will be up for sale in the spring and has always been really well maintained. Suggestions? Recommendations? This is not a track or AX toy, just a canyon cruiser. Next trip is to SoCal just after Christmas. What about driving the car with this rattling cat, any issues other than an O2 sensor not being happy?

Personally I'd look at some 200 cell sport cats. They are not crazy loud but are a little pricey especially if you look at x-pipes. With Black Friday coming up I'd make a purchase then and get some savings.

If you're planning to sell in the spring, look into getting a used set of stock cats?

Maybe combine SP's suggestion and get sport cats for the C4S and put it's old cats on the C2?

Someone - Carnewal? - rebuilds stock cats...unless I hallucinated that. Might be cheaper than finding CARB-approved aftermarket cats.

If this was on the C4S I'd consider this route. The cab is just right for my wife to enjoy it still. Gets me thinking about swapping from the 4S though. Hmmmm...

Thanks Gnat and Sneaky Pete.

Not sure about used being worth it. Rebuilding could be an option if it makes financial sense and actually works.
