A vote for the High flow cats

+ Runing w/o the cat makes your interior smell like fumes not to mention the black soot all over your bumper. All my DSMs smelled like exhaust from running with no cat. I couldn't smell it cause I was used to it though. I just got tired of everybody telling me that my car stunk.
I bought a 3" stainless HFC from Jegs, cut a section out of my test pipe and welded each end to the cat. Make sure to keep the overall length and flange yaw the same.

^ This is what I would have to do as well. in order to switch to a high flow cat. Since I dont have a test pipe per say to take the place of the stock cat. Oh and my car doesnt smell bad at all no one has ever told me that either sure you dont have an exhaust leak. The funny thing is that with our test pipes we probably still put out less emmissions than your buddy Iroc, Camaro, Mustang, or F350

The carbon monoxide from your car will not change the earths lifespan. Its not going to blow up. It's not going to hurt the planet one bit. It will be here, long after you go.
Yes we will die before the earth ends but we dont have to leave a ****ty place for our kids and grand kids to live in. And it can be fixed if we wanted but again just like our congress men if it wont affect us in our lifetime then we dont care. We have that mentality why should we expect any better from the people we put in power???
And if your Rep in congress aint doing **** about get off your *** and get involved in doing something about that. its time we stop making excuses for everything and start making an effort. everybody is always complaining and pointing the finger somewhere else but nobody tries to fix **** anymore while we all get ****ed and they get rich.

Our recorded history of weather is too short to make these kind of claims. Yes, the temps are rising, but claiming it's just because of pollution is ignorant. 20 years ago everyone was freaking out about global cooling. We have no idea of the macro climate changes the earth under goes normally. One volcano eruption puts the human race down to less than 1% of the total pollution for the year.
I believe in good stewardship of the planet and resources we have been given. Cleaning up after ourselves is part of that process. However, get some perspective on the issue...

Nowadays the High flow catalytic converters are giving almost the same gains of the test pipes, but without pollution.
Does the 5whp more (test pipe vs High flow cat) worth the environment degradation?

i get worked up too.... the environmentalist only show their side and the people against it only shows their side, so its hard for people to get proper info unless they are willing to invest time in doing their own research.... most of us wont because we dont have the time or we feel the time can be better used for something else.

the emission laws in this country are out of whack. i look at all the trucks who dump so much pollution everytime they take off or hit the throttle hard.
the only reason i would not want to run a test pipe would be because of the noise level. i like my performance and looks of the car to speak for themselves, not the noise level it produces. noisy vehicle takes away from its mature status and grabs too much attention for negative reasons like the go slow harleys. on the otherhand my friend has loudmouth catback on his GTO and the thing sounds awesome. too bad the EVO can't be made to sound that way.

I run a cat because I like the fact that my car(while modified:272's,alky.etc..)is still pretty much "street legal". I run a flash and a works hi flow cat and pass the obd test and the visual test with no problem. i think that you can still effectively make lots of power with a cat. When i do switch to a big turbo I plan on keeping the cat and see what kind of #'s are achieved. Plus the fact that the unfiltered exhaust fumes can induce headaches in traffic. My .02 I drive the car every day and while I do the cat will remain on the car,once it becomes a weekend car we'll see, but I am not sure if the gains will be really worth it.

well i think the best solution is to run a HFC if you drive your car daily and use a test-pipe if you compete. it only takes a few minutes to make the swap and this way we will have both worlds... a "clean" daily driven car and a flame throwing monster when racing...

I run a cat to try and keep the car as low key as possible to not attract attention from cops and teenage punks by reducing both the sound and smell.
