Cat's are done. Need help.

[911Etarga]

Has anyone ever put a sensor delete/dead head on there catalytic converter? The dealer wants $2300.00 to replace them, so I was wondering about other, much less expensive options.
Any help would be much appreciated!

P.S. it has 120,000 miles.

Not sure what you're asking.

So your catalytic converters are dead (you said "cats are done" in your title, so I'm assuming that means either your cats are dead or you've installed new ones)

But what do you mean by sensor delete? You want to bypass the oxygen sensors because the cats aren't functioning anymore? You have four oxygen sensors (two upstream of the cats and two downstream) and I'm not sure if there is a way to bypass them without living with the check engine light on all the time. Why don't you just buy aftermarket cats instead? Much cheaper than dealer prices.

go some place else & get an estimate to replace em.

I lucked out - mine when bad this past summer before the 7year 70,000 Wonder if insurance will help at all? That's a big hit.

What are you guys using as a gauge that your catz need replacing? the only car truck I ever knew of that needed the catz replaced was my grandparents Cougar needed tehm when they collapsed and the car wouldnt even start due to extreme backpressure.

When the cats are truly bad, the oxygen sensors will tell you. But the tricky thing there is that the oxygen sensors themselves can go bad, which might lead people to think the cats are bad. So you need to make sure the oxygen sensors are good before you replace what you believe is a bad cat.

Good info, I've had many O2's go bad in cars over the years, my 94 civic had 3 over its life but never a cat.

the 02 sensors are just electrical sensors that can be "fooled" with resistors. People do this all the time with02 simulators. I dont have any info for you though, but I'm sure it can be done.

Agree, I would be pretty surprised if the cats are bad. You just don't hear about that on todays cars much.

If the cats are bad, you could go with a Magnaflow high-flow cat or something like that and it should be fine and probably cheaper to have that welded in.

I thought about deleting the front 2 cats but I'd rather replace it with long tube headers and that gets pricey with the O2 simulators in there.

rockauto.com has them from $73-$400 and I bet you could find an independent shop to do the install for under $200.

I have these resistors on my 97 chevy and they do make the trunk run good but the CE light is on all the time and I have a machine to clear the codes but they just come right back. CAnt remeber the cost of them as it was years ago when we installe a true dual exhaust. LOTS cheaper than converters though.

A lot of performance exhaust shops can trick the 02 sensors for you. I would just go ask around locally.

TOYLUVA: The whole point is so the CEL doesn't come on. Something must not be working right.
