Does anyone not want to go cat-less just for the sake of air quality?

Just curious.

they make hibrids to even out my cat-less vehicles :)

I have seriously considered getting a high flow so not to help global warming. I kinda think I am a jerk for being catless but I do recycle as much as I can as well as pick up garbage that I see in my neighborhood.

I have a Mustang making over 500 rwhp with no Cats and my '89 passed emissions standards and would be legal if they did not worry about the emissions devices. You can make a car so clean without all the emission parts but the manufacture would need the local dealership to program the car for its physical location because you can only get the computer to adjust for so many changes in altitude and gas quality.

i'm not too worried about it, i plan on going cat-less for a little while, most new cars run fairly clean while cruising and idle, the most polluting times are accel and a quick throttle close... my sister's honda blew all 0s even on an emissions dyno...

I'm cat-less and am not planning on going back. The car's been that way for about 30k miles. As far as global warming is concerned, today's cars aren't affecting the change as much as people would like you to believe. To each their own though so.....whatever.

while i am of the mindset that there are alot worse air polluters than cars, i am all for keeping the cat. as for the rest of you, if you need to go catless to make just a couple extra hp, well face it your car just isn't all that fast anyway so just put the cat back on :p

I had the "one more car won't make a difference" attitude until my recent trip to South America.

I was in a few busy cities that obviously don't have much in the way of emissions laws. The smog was horrible. I couldn't breath. The stench was horrible. It actually burned your eyes, nose and throat. After 15 minutes of exposure, my clothes would smell like exhaust for the rest of the day.

I'm now considering installing a high flow cat.

I never thought I would hear this from you.

I do see both sides of this argument, however my DP has a cat and I like it that way.

Mostly 'cause stinky exhaust sucks.

Here's a thought though, cavemen invented fire and in the thousands of years since Ray first started rubbing some sticks together we have to think of a better energy solution than simply "burn ****". That is absolutely sad. IMO the world has much bigger problems than which members of ClubWRX do or don't have cats on their cars right now.

BTW: I just took a huge **** on mother nature and then wiped my ass with a spotted owl.

I'm catless and guilt free. No e-checks in my county and I doubt any of the cops know what a cat looks like or could recognize the sweet sweet smell of mostly combusted, catless sunoco 94.

A catless car produces less green house gasses than a catted one operating in a similar manner/environment. However a catless car does produce more smog type gasses than a catted one.

My area has good air quality but is still affected by global warming as it is, well, global. So I'm catless. If I lived in an area with smog problems then yea, you could call me an ******* and I wouldn't refute it. My area has no smog problems so the catted drivers are the *******s, they just don't know it.



Cats convert gasses like carbon monoxide and hydrocarbons into carbon dioxide which is BY FAR the greatest cause of global warming.



Yea, I know.:tongue:

i would not go cat less in my car because of the environment...
after the meet in oregon last weekend, i was so tired of the smell of peoples exhausts!

If it's important to your principles, and you somehow will have a clearer conscience by running cats, then by all means do so. The fact is, though, that we as "catless car mod guys" make up an insignificant, tiny, fourth decimal place speck of the massive car population.

Any difference in smog or global warming as a result of all of us replacing our cats would be negligible at best, and probably undetectable.

^^This statement coupled with the fact that my catless Invidia Dp cost $250 as opposed to $450 for a catted DP (or around there) means I will stay that way for a long time (no inspection until 2010):cool:

thats a great attitude ray. so what if EVERYONE thought that way? maybe india and china should say that, oh well everyone else is doing it, that should make up for us. why should we pass any emissions laws to cope with our ginormous auto growth? or how about all the yahoos here in america that have an old, rotted out cat thats now innefective? for every one enthusiast who took his cat off on purpose there's 10 bubba's in old cars with a busted cat with the same attitude. is that still a tiny smidge of a percent?

its just like saying "oh, well my one vote isn't going to make a difference". you know what, there's a million other people out there saying the same thing. imagine if every one of them thought differenly: that could turn a whole election.

not to mention that the real big cause, IMO, of pollution is factories, manufacturing, etc. laws and regulations to clean them are never going to get changed if we the people have the "well i'm just one guy" attitude and dont push the govt to make a change. that all starts with how we treat ourselves.

What if I could fly? What if UFO's come down with giant Indians in them? :rotfl:

The fact is that they don't. 99.999% of people buy cars, and drive them as is. You can't equate a smell to harmful emissions, btw, modern fuel-injected cars with sensors put out extremely small amounts of harmful emissions, even without cats..

I recycle and engage in other eco-friendly activities, but I'll be honest: in this case, my desire for a more drivable, enjoyable car overcomes any environmental idealism I may have. :shrug:

I'm curious: do you also think that people that own vintage (pre-1970) cars should be forced to add cats to their vehicles?

I'm also not really following your "factories pollute, so you should put a cat on your car" logic.

I'd accept a catless up pipe but will not drive a catless car. I commute a long way in dense traffic in a basin world famous for smog that's made tremendous improvements, and I want things to keep moving that way. I like breathing.

I've been to India on several occasions. In 1999, Mumbai had this terrible stench of diesel/kerosene in the streets. You really couldn't stay outside for long without feeling a bit suffocated. You'd also get those nasty black boogers.

In 2005, the air was considerably more tolerable. There was quiet a dramatic difference in the air quality. A law had passed that all Auto Rickshaw's and Taxi cabs had to run on Compressed Natural Gas (methane). Clean normal greenish white boogers.

Emissions are there for a reason, and I've seen it work first hand. If I were to go stage 2, i'd go with a high flow cat. Clean boogers FTW

I'm starting to become a CALI snob. I have a CAT on my STG 2 WRX. Cobb even says in their map notes the difference between cat less and catted was insignificant IIRC +-1hp.

I have come to appreciate air quality especially inside buildings. Here in Cali it is illegal to smoke inside any building period. There are no "smoking" or "nonsmoking" sections anywhere. You can't even smoke at bars. At first I was against it, but now 10 years later I am sooooo glad it passed. As a non smoker in the 80's I never realized how much smoke I was inhaling until it stopped. Whats funny is that all of my friends/family who do smoke, out of habit go outside of their own house to smoke, and won't smoke in their car. Now attribute that to air quality and walking down the street. I can't wait to reach this same point with air quality.

Let's also not forget FIA rules dictate a catalytic converter on all rally cars. If the works cars can make stump-pulling torque with a cat in place, I think cats are not really a performance issue.
