Our cars have two cats, one attached to the exhaust manifold and one in the front pipe.

The one in the front pipe can be removed without a CEL as there is no down stream sensor to monitor it. If you replace your headers with a catless version, you will get a CEL with a stock tune. I have heard the defoulers work OK for getting around that.

Right now I am on a stock tune with headers and get a CEL almost once a day. (50 mile commute.) I just clear it with torque app.

lol chances are I do actually - I walk to the train station more than I drive my FR-S.... and commute via electric train to NYC... which uses electricity from a nuclear power plant I guess the point I was trying to make is - the mentality needs to start going the other direction. I'm not spewing anything, no need to be so defensive. Kumbaya

Haha touche.

Running full catless is douchey and pointless on anything but a track only racecar.

Ask anyone who lived in LA in the 60s and 70s if cats are a good thing.

Yeah auto emissions isn't the biggest offender, and it won't bother you or me today, but its my kids who will have to deal with the socioeconomic impact of climate change in 20 years. So please do me a personal favor and not f-up my kids' future environment, they have enough crap to inherit as it is.

"Releasing a study" doesn't quantify and amount of proven fact.

if you're truly worried about your kids find a new planet... Geneticly modified foods, big pharma medicines, chemicals in everything... its not "global climate change" i'd worry about...

Just try finding a peanut butter with the ingredient "peanuts."

If you don't already realize its next to impossible to find and if you do its Genetically modified peanuts ground for the PB.

So inclosing, screw your concerns because big government and nuclear technology is doing and will do more harm than any catless car

Uh. OK. Peanut butter. Fear (or is it faer) peanut butter. Dont see how that relates to individuals choosing to break the law and pollute the air, but thanks for your wisdom!

My lawn mower is catless.... So is my weedeater and any bike you find for sale.


Also they changed "global warming" to climate change because they had lost the debate. Now anything abnormal is our fault.

Look at the "fix" taxes and regulations which will never solve any problem. It's about control.


No point except price to not run one cat though. It won't help performance. No need to have two either though.

God you guys are making my head hurt...


Reasons to run catless:
- You're cheap
- You're running leaded gas


High flow cat vs a straight pipe is within the statistical noise of a dyno.


Also, it's not about global warming or anything like that, NOX is a serious health risk to your local community. I dunno about you, but I like breathing.


Not to mention you guys are comparing it at idle vs actually driving the car (idle is lean, WOT is rich, hope that person behind you doesn't have their windows down on their eyes are going to be burning).


Comparing it to a diesel is a bit dumb too. Diesel exhaust LOOKS polluting, but it's mostly soot and doesn't have the same health issues.

I have had plenty of full catless cars. Never noticed any smell from them. Anyone ride motorcycles? The vast majority if them have no cats...

The new diesel trucks actually exhaust cleaner air than the air its ingesting here in new jersey

When will you be joining al gore on the hunt for manbearpig?...

haha, never. i never claimed to care about the environment enough preach against running catless. the point i was trying to make was, that thinking that taking a cat on or off your car is going to affect anything is like thinking its a good bet to order a diet coke at mcdonalds.
