What would happen if I took the Catalic Converter out of my car? What would side effects be?

Question

96 Gs 300.

Answer 1

Extreme pollution and violation of smog laws.Gas mileage per gallon would get worse.

Answer 2

Your taking a beating for even suggesting the idea of removing the converter. Unfortunately in todays hi-tech cars it just won't work because it is part of a system designed to remove emissions. If you remove the converter most likely your car will run like crap.

However there are pros and cons to the "system"

Catalytic converters have proven to be reliable devices and have been successful in reducing noxious tailpipe emissions. However, they may have some adverse environmental impacts in use:

The requirement for a rich burn engine to run at the stoichiometric point means it uses more fuel than a "lean burn" engine running at a mixture of 20:1 or less. This increases the amount of fossil fuel consumed and the carbon dioxide emissions of the vehicle. However NOx control on lean burn engines is problematic at best, and many lean burn engine manufacturers are considering rich burn variations. Another solution is to increase the amount of biofuels used - if 100% biofuel was used the engines would be CO2 neutral, presuming no fossil fuels were consumed in production of the biofuels, which currently is far from the case (see energy balance of biofuels).
Catalytic converters are "estimated" to account for 50% of total nitrous oxide (dinitrogen oxide, 'laughing gas') emissions to atmosphere. While N2O emissions in these concentrations are not harmful to human health, it is a potent greenhouse gas, accounting for around 7% of the overall greenhouse effect despite its small concentration in the atmosphere. The California Air Resources Board is investigating this issue, and will introduce legislation to address it if necessary.
The manufacturing of catalytic converters requires palladium and/or platinum; a portion of the world supply of these precious metals is produced near the Russian city of Norilsk (about 15%), with significant negative environmental effects due to the lack of environmental protection legislation. [2]
It can be argued that catalytic converters have reduced toxic emissions and smog at the expense of increased greenhouse gases, however anyone making this argument should consider the California Air Resources Board reports on improvements in Air Quality that have been achieved over the last 30 years.

Answer 3

Your car will start to smell like rotten eggs. The converter is designed to take unburnt fuel and "catalyze" it with platinum to keep pollution down. Better designed cars, like your GS 300, usually have catalytic converters that don't slow the exhaust down very much and are pretty efficient. Removing your Catalytic Converter is a bad idea and can eventually cause your exhaust vavles to burn up. Get a good tune-up and use a higher performance exhaust, if you want more power. Don't ruin it!

Answer 4

A catalytic converter is a device used to reduce the toxicity of emissions from an internal combustion engine. A catalytic converter provides an environment for a chemical reaction wherein toxic combustion by-products are converted to less-toxic substances. With that being said, removal of this device would significantly increase the amount of toxic gases produced by your engine. If the state/county/parish requires that you live in requires emissions testing, your vehicle will most likely not pass.

Answer 5

TRUTH IS, You will gain Horsepower, and maybe some torque. Car might be a little louder, usually not that noticeable. As far as all the illegal garbage. Just depends where you are, and if you state has a smog test or safety inspection or any of that to get caught. Illegal but who cares if they not gonnna check for it.

Answer 6

your engine will run like crap. it will go into "limp-home" computer mode and have poorer performance and economy. you will also not pass emissions and have a hard time selling a car with a check engine light on.

it's also very, very illegal, with a possible 10,000 fine in some states if you drive it on public roads.

just get a high flow cat from a reputable manufacturer that is legal in your state. that give you 1% more performance, but you'd probably be better off leaving it alone if it's running okay now.

Answer 7

Your car would then spew unburned hydrocarbons in the atmosphere, would fail its biannual "smog test," and might be flagged as a "gross polluter" by the automated roadside checkers.

Answer 8

You would be looking at a violation for illegal modification of your exhaust (especially in California). It also would not run as smoothly or efficiently.

Answer 9

You would not notice much change. You would be adding more pollutants. If you were caught the fine would be expensive

Answer 10

It would be louder you would get more horsepower and torque; but, you wouldn't be street legal anymore.
