better start with NASCAR then.

lol... if you feel removing a cat is bad you really have no place thinking about more power in a yaris. You should have just bought a corolla or a camry and called it a day.

[cali yaris]

^ LOL. caveatipse FTW

The OP thinks I belong in jail and lose my car.

/unsubscribed

[mikenacarato]

my volvo ran with no cats and didnt put out enough emissions to throw a red flag.

i think caveatipse is back.

[RacerFreakXXX]

this is really funny... I know for a fact big work trucks put out more emissions than my yaris would with a straight exhaust.

If you can afford to increase the size of the air fuel input to your motor, you can afford to install a larger catalytic converter to clean up the unburned fuel out of your exhaust. Removing the catalytic converter is a crime under federal and state law. Since some turbo kits come with catalytic converters, I am not the only person who thinks that environmental protection and power increase are compatible.

Tons of people break the law on a daily basis. Now laws are there as a guideline, and you can use your own judgment on whether the juice was worth the squeeze. A little bit of pollution is not the same as me shooting someone. Same as speeding on a highway is not as bad as through a neighborhood where kids are running around.

Also... turbo = going fast = against the law, so if you are spending 3-5k to pass someone on the highway but won't break 65 to do it there is no point ;)

not new emission semi trucks.... :)

Actually, in the state of Ohio spending more than $5,000 qualifies you for a collectors plate that allows you to be omitted from emissions testing. That is what I will eventually do to circumvent having to e-check MY car with MY exhaust, which by the way has no catalytic converters.

To say it is criminal not to run any cats shows that you lack basic understanding of many car enthusiasts because that statement alienates some of the most impressive builds around. Frankly, I more often see turbo cars WITHOUT cats than with. Reason is they rob the car of flow, ie: they cost you horsepower, which defeats the purpose of having a turbo to begin with. Another common thing is to punch a catalytic converter out so it appears you have one when you don't for all intents and purposes. My point is I would be careful about wild generalizations referring to people without catalytic converters. Many of the people that could potentially help you create a kit won't have them.

If you went into a performance shop saying things like that, they'd laugh you out.

Frankly, I don't think you should get a turbo kit. Having a system on a car like this requires a big pocketbook and a basic level of understanding for when things go wrong, and by some of your comments on this thread I have my doubts. No offense meant at all, I'm just being realistic. Get a faster car.

I believe she is trying to go for the eco-boost that ford is doing if so then go buy a ford!!!

[RacerFreakXXX]

yay for new twin turbo taurus... rofl

[etheliters]

+1

[cali yaris]

^ HUH? I'm in an altered reality.

1. Acceleration is half the fun, and it's legal.

2. going fast = not against the law, AT THE TRACK. The other half of the fun.

So many opinions, laws, cats, turbos, concerns, etc, etc.

EllenBetty Please!!!!! get a CUSTOM / Eco Friendly / Street Legal / Low boost / Anti smog / Cat deleter crushing / ToyoHonda / Law Follower Turbo kit!!!!!! And be Happy

For the record, the biggest concern with catalytic converters is the not reducing carbon emissions, but the chemical reactivity of those emissions and their effect on air quality. They really do serve an important purpose, and its not terribly difficult to find a free-flowing cat, either aftermarket, or simply purchasing one intended for a larger engine (a late model V6 cat off a single exhaust vehicle can be found at junkyards pretty cheap.)

For those who want to know, here is a better explanation:

A two-way catalytic converter has two simultaneous tasks:

Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2
Oxidation of unburnt hydrocarbons (unburnt and partially-burnt fuel) to carbon dioxide and water: CxH2x+2 + 2xO2 → xCO2 + 2xH2O (a combustion reaction)
This type of catalytic converter is widely used on diesel engines to reduce hydrocarbon and carbon monoxide emissions. They were also used on spark ignition (gasoline) engines in USA market automobiles through 1981, when the two-way converter's inability to control NOx led to its supersession by three-way converters.
Three-way
Since 1981, three-way catalytic converters have been used in vehicle emission control systems in North America and many other countries on roadgoing vehicles. A three-way catalytic converter has three simultaneous tasks:

Reduction of nitrogen oxides to nitrogen and oxygen: 2NOx → xO2 + N2
Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2
Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + 2xO2 → xCO2 + 2xH2O
These three reactions occur most efficiently when the catalytic converter receives exhaust from an engine running slightly above the stoichiometric point. This is between 14.6 and 14.8 parts air to 1 part fuel, by weight, for gasoline. The ratio for LPG, natural gas and ethanol fuels is slightly different, requiring modified fuel system settings when using those fuels. Generally, engines fitted with 3-way catalytic converters are equipped with a computerised closed-loop feedback fuel injection system employing one or more oxygen sensors, though early in the deployment of 3-way converters, carburetors equipped for feedback mixture control were used. While a 3-way catalyst can be used in an open-loop system, NOx reduction efficiency is low. Within a narrow fuel/air ratio band surrounding stoichiometry, conversion of all three pollutants is nearly complete. However, outside of that band, conversion efficiency falls off very rapidly. When there is more oxygen than required, then the system is said to be running lean, and the system is in oxidizing condition. In that case, the converter's two oxidizing reactions (oxidation of CO and hydrocarbons) are favoured, at the expense of the reducing reaction. When there is excessive fuel, then the engine is running rich. The reduction of NOx is favoured, at the expense of CO and HC oxidation.
Oxygen storage
Three-way catalytic converters can store oxygen from the exhaust gas stream, usually when the air fuel ratio goes lean[4]. When insufficient oxygen is available from the exhaust stream the stored oxygen is released and consumed. This happens either when oxygen derived from NOx reduction is unavailable or certain maneuvers such as hard acceleration enrich the mixture beyond the ability of the converter to compensate.

Unwanted reactions
Unwanted reactions can occur in the three-way catalyst, such as the formation of odiferous hydrogen sulfide and ammonia. Formation of each can be limited by modifications to the washcoat and precious metals used. It is difficult to eliminate these byproducts entirely.

For example, when control of hydrogen sulfide emissions is desired, nickel or manganese is added to the washcoat. Both substances act to block the adsorption of sulfur by the washcoat. Hydrogen sulfide is formed when the washcoat has adsorbed sulfur during a low temperature part of the operating cycle, which is then released during the high temperature part of the cycle and the sulfur combines with HC.

Also, a test pipe is a simple and very effective solution for track/racing situations on a car that will be street-driven too. Simply fab-up a pipe to replace your mid-pipe and it only requires a few bolts to be removed and replaced to make the quick switch, kinda like cut-outs back in the day.

or just buy a car that came turbo from the factory.
