Nox: max 0.9300, mine 0.1847, avg 0.2162 PASS

no idle test..

second time..

HC: 0.0254 PASS
CO: 0.9669 PASS
Nox: 0.0776 PASS

i went right away this time (after install), with the car warm up of course.

so it IS the uppipe cat... i didn't believe it at first, but i was wrong..
Taken from this thread HERE

And that's just for running without the uppipe cat.

Forgive me for being rude, but just like Necromancer said, you're worried about your bumper? This is the air we all breathe, and for a few more horsepower, you're going to spew out not a little more, not a lot more, but more than 30 times more pollutants? That's downright obnoxious. Please, do us all a favour, keep ALL your cats on.

Oh god. Cry me a brown, unburnt hydrocarbon river.

I'll worry about my cats when they stop selling 8000 pound road tanks that get 5 mpg and come with a tax write-off.

I have had no problems with my aspen white bumper and catless setup. I get little specs on it, but they wash right off. Somewhere on here I saw someone was now offering a carbon bumper protector that looked pretty hot. That would look better then that aluminum peice that has been around a while now.

Yes, but also he was running a BOV and thus affects the air being metered possible. Then again, people have passed aircare with a BOV and the stock 2 downpipe cats.

Some of the guys in Cali have passed the sniffer test with just one cat in the downpipe.

Uppipe cat is for cold start only.

No, it won't make little kiddie lungs turn black as he drives by...

Does you grandfather's old Plymouth Charger do that? It's putting out WAY more pollutants, and burning more non-renewable resources doing it!

Go drive a SMART car or something if you're feeling bad.. GESH!

go take a bus if you really wanna be enviornmental friendly.

certainly there is an extra external cost asscoiate with running catless, and we all pay for the extra external cost since the car will consume more fuel if you run catless, so you pay more taxes as you buy more gas. and the taxes collected from taxes will go to the health care. same thing.

I could rant but not because I really care one way or the other. The "logic" in this thread is just so astounding that I feel like debating just for the sake of pointing out what terrible arguments are being made. But I'll just keep my mouth shut and quietly shake my head.

Economics you have to take into account the magnitude of the forces at play. The extra fuel you use by running catless is pretty insignificant (maybe 5%?), as is the extra gas tax you pay, while the extra poution you're causing is 3000%?

I'm sure an SUV with cats pollutes less than that. I'm not being an environmental nazi or anything, just pointing out the falacies in the reasoning around here.

Besides, if you're not part of the solution you're part of the problem so spare me the "well he's polluting too" bull****.

um...

i used to get 380 km per tank when my car was 100% stock.

now i am running 3" TBE catless, intake, UTEC. and it runs 280 km per tank max. i will get 280 only when i stay off boost. obviously it is much more than 5% man. at least for me.

as for the pollution. there are 2 cats in the STi, and it was design to take up about 90% of harmful elements, so if you running the car stock with 2 cats on it, it still has 10% of harmful gases coming out from your exhaust. now i am running catless and 100% all coming out from the exhuast. i can't see how your calculation of 3000% came up?

Ok, so you're using 35% more fuel. I was using the figure of 30 times more polution another user mentioned. But if I use your numbers of 10% vs 100% assuming you were running stock but catless, you'd be causing 1000% the pollution. Then again, since you're using 35% more fuel you're certainly causing at least 1350%+ pollution, and probably a lot more because I'm sure your ECU tunning isn't as clean as stock.
