no catalytic converter??


Recommended Posts

A catalytic converter (colloquially, "cat" or "catcon") is a device used to convert toxic exhaust emissions from an internal combustion engine into non-toxic substances. Inside a catalytic converter, a catalyst stimulates a chemical reaction in which noxious byproducts of combustion undergo a chemical reaction. The type of chemical reaction varies depending upon the type of catalyst installed, for example current North American gasoline powered Light Duty Vehicles are fitted with a Three-way Catalytic Converter which reduces carbon monoxide(CO), unburned hydrocarbons(HC), and oxides of nitrogen(NO, NO2, & N2O) to produce carbon dioxide(CO2), nitrogen(N2), and water(H2O).[1]

 

Catalytic converters were first widely introduced on series-production automobiles in the United States market for the 1975 model year to comply with tightening U.S. Environmental Protection Agency regulations on automobile exhaust emissions. Catalytic converters are still most commonly used on motor vehicle exhaust systems, but are also used on generator sets, forklifts, mining equipment, trucks, buses, locomotives, airplanes and other engine fitted devices. Usually this is in response to government regulation.

And no, I didn't type all that. Copy and paste.

In some areas of the country they are needed to pass emission tests. No Cat, no pass. As for the Renix running without one, it will run quite well without it. It is a violation of Federal law to remove them.

A catalytic converter...is a device used to convert toxic exhaust emissions from an internal combustion engine into non-toxic substances

 

That's enough reason for me right there...and no, a RENIX with no cat would just be a straight pipe...if you had a muffler or not as there is no downstram O2 sensor.

 

Trail rig or not, you'd still be spewing all that crap. Keep it.

You can run w/o the cat , you just need the 02 sensor still installed . You may or may not get a CEL , experiences can vary . You can be fined in the USA because it is a federal crime . Why is arguable , there's just as much evidence pro or con to it's benefits .

 

Some facts about cats

- they don't rob you of more than 1% power when functioning properly(I will say older cats are crap , the newer ones work and last better)

- wheeling w/o them can result in teary eyes

- vehicle inspections can require all original equipment functional

- "According to Title II of the EPA Clean Air Act (Enacted Jan 1 1988) there are multiple regulations concerning the use or misuse of aftermarket catalytic converters, or the removal and/or modification of a stock catalytic converter. According to various parts of Section 203, all aftermarket catalytic converters must be EPA certified, and your car must have a gas conversion device of some manner. If not, both you and the installer are punishable of a Federal Offense by Section 205 (a). The operator's fine can be no more than $2,500 and the installation agency no more than $25,000."

- there is no excuse not to run a cat , they can be had for the price of a tire .

Your O2 sensor is before the cat, so youll be fine if the cat is not there. What would be even better though if you really don't want to run one is to take your existing converter and knock the guts out of it and either sleeve it and reinstall it, or just reinstall it as is, that way if theres ever an issue, you can point to it and say there it is. My boss's MJ is like that (unintentionally) and it runs fine ( its an 88 4.0 auto). My 2.5 has been sleeved and reinstalled and runs great. But if you have a good converter and the engine runs right, theres really no need to mess with it.
