Removing Catalytic Conv. on '99 V6 SE

[PeteGLH]

Has anyone ever experienced removing the catalytic conv. on their Solara/Camry?

CEL's?

Anyone also ever tried to remove the Cat, and just move the O2 sensor all the way to the back of the car to kinda cheat?

Maybe there can be a way to cheat the signal from the O2 sensor to the ECU by adding a sort of resistor and/or Zener Diode?

My Cat is shot, and I really don't want to replace it...

Any feedback?

Why would you want to remove your cat? the power gain would be very minimal if at all unless you have a full cat back ad custom Y pipe / headers. If you are set on doing a cat mod get a universal OBD2 compliant cat from magnaflow and your CEL will not come on. IF you really need to remove the cat get an O2 sim and not an ebay one and install it. Get one from underdog racing. Do a search for 02 simulator.

the ticket for catalytic removal is very very expensive.

I don't believe moving the O2 sensor would cheat the ECU. O2 sensors, like catalytic converters must be hot to work properly. I'm not sure of this, but I believe moving it to the back of the car would probably cause a CEL.

90% of all automobile pollution comes from only 10% of the cars. Removing the cat is ecologically irresponsible. Universal cats are not that expensive and your car will run the way it was intended to if you replace it. If you can't afford to replace the cat, you shouldn't be driving. Are you going to remove all the oil the next time it needs changing? Might as well toss those spark plugs and that pesky old air filter. Those don't last forever either.

I think I speak for a lot of people when I say, "I'd like some clean air, please."

Pete,

Have you checked wrecking yards in your area? Chances are you'll be able to find a cat from a low mileage but wrecked Gen1 Solara or Camry for very little money.

Your engine and its sytems are designed to work with the catalyzer installed. Pulling it out will throw everything out of whack. You'll lose performance, probably get rotten gas mileage and...oh yeh, your exhaust will smell like a 1964 Bel Air.

Cheers

not sure you can "legally" buy or sell a cat. to be installed on a vehicle. I think they are pulled pretty quick at the salvage yard and sold for scrap.

[Midias]

I think all wrecking yards have to discard the cats. I would search for a used Y pipe on ebay the cats are connected to those and cannot be removed without cutting. A universal can be installed no prob with a little cutting and welding.

Ozone! That is your screen-name? You choose a fictional layer in the atmosphere created by environmentalists groups and supported by auto industry lobbyists who made it up to sell over-priced vehicle emissions parts. And if it is there we (I) will burn it up eventually. Cook, burn, sizzle.

Yeah, the 10% of aged untuned carburated cars still on the road. 3 of my current street cars and one I recently wore out and retired are/were running cat-less. The one I did not find a legal loophole for getting exemption waiver for emissions testing still passed the tailpipe sniffer. Dang cats burn out on racegas, honeycomb/matrix cells break landing the jumps and having a burning hot converter on your car is bound to start a forest fire while offroad taking creative short-cuts which I do a bunch intentionally or not. The quickest route is not always paved and I'm in a hurry. Lawn grows back and posts can be replaced.



My 3 cars on the road now I somehow misplaced the EGR systems, vapor canisters, air pumps, cold start-up emissions gizmos, .....very mysterious.

Want zero pollution? Get an O-Pipe.



You've heard of the Y-pipe, the H-pipe and the X-pipe, nothing can touch an O-pipe. It provides 100% back-pressure, increases torque and eliminates pollution. Being in the auto industry, I can get you a deal.

HAHAHHAHAHAAHAH I LOVE MIDIAS JUST FOR THAT COMMENT HAHAHA

[Turbosolara]

it is illegal for junkyard to sell used catalytic converter. 'i would say just go for the after market high flow cat. it sounds better anyway.... i hate how straight pipe sounds

ProRally,

You are of course entitled to your misguided opinion, but there are a couple million people living in LA that can attest to the fact that their air quality has improved over the last decade or so. But I'm sure that automobile regulations have nothing to do with that.

I have a suggestion for proving my point. Why don't you just start your car in the garage with the garage door closed and sit there for a while.

If you think a billion cars all driving around belching filth into the air are not having any harmful effect on the atmosphere, then you are sorely mistaken. Denying this is just a way for irresponsible people to do what they want with a "clear" conscience.

I'm looking at this very moment at a Summit Racing catalog and there is a universal catalytic converter in here for $64.00. If he can't afford $64.00 for a car repair, how exactly does he afford to put gas in his tank. What's he going to gain by removing it? 1 Hp? 2 Hp? It's just ridiculous.

Take the bus!

Pollution per horsepower would be little different than you doing the same thing. Like I said, I've had cars with gutted cats still pass sniffers with flying colors.

My daily beater gets an annual if not semi-annual dyno tune for proper A/F mixture and ignition timing. Proper tuning, not dilution is the solution to pollution.
