just put a bullet in a cat shell. it is quick, easy, and cheap. the power loss will be minimal and you will still get to hear the LS1 when you go to WOT

what other thread... link my lazy ass

holla

jeff just had a heart attack

cats = bad... egr = bad... emissions is not FTW

:werd:

Ha, you guys fall for that propaganda on the interweb!:scratch: Catalytic converters reduce more harmful stuff than they might increase NOx. And cows are creating a heck of a lot more ozone problems then catalytic converters are. And running a modern engine on unleaded fuel without catalytic converters creates even more bad emissions than the older cars that ran on leaded. So when you remove your cat(s) you are polluting even more than we did back in the 60's & 70's! But if you don't like catalytic converters, then go out and develop a better emission's control solution that doesn't rob power or efficiency. But I doubt you'll find a better solution that reduces smog emissions without having another adverse effect.

As much as I love clean air, I leave that to hippie Jeff. All I see a bunch of guys wasting time & money on their cars for almost no real world gain, while simultaneously causing unwarranted trouble. Ugh, failed emissions, buying parts to make the useless mods work (hi, I want to buy cat shells, WTF?), reprogramming ecms, breaking parts and unwarranted downtime, even risk of impoundment??

Ha, been there, done that, already wore out the t-shirt. Spend that time & energy on doing something useful to your car. Work smart, not hard.

Im not gonna lie, Jeff and Scott are right.

theirs only two excuses to not have cats one vehicles.
1. Its a race car
2. Its a historic QQ plated car.

Would you rather have a car with cats that runs 13.2 then a car with out cats runing a 13.2??

Just think of what would happen when an officer knows his ****.. Just get cats then get a manual cut out.

As far as egr and air, the only excuses to take them off is if the intake doesnt have it or the headers dont have it..

Im sorry for ranting but Im kinda jelous :lol:

i believe the figure was ~10% of the ozone related problems are caused by cars. thats a small amount in retrospect. sure the answer to our ozone problems isnt gonna be solved with a emissionless automobile, so why even bother being so strict if the tangible gains are so small? cats are expensive and for all we know we may be wasting more energy on making and enforcing emissions then we are saving

I actually agree that cars are unfairly demonized. Hell, I think the proliferation of batteries and electrical (and plastic) gadgets are an impeding environmental issue – but short sighted greenies like things because they don’t see the pollution. Idiots.

Then again, every little bit helps. That is why I don't argue the reasons they are there - just the reasons why not to bother with screwing with them. The payback vs effort & trouble is rather low.

um..jet airplanes are way more harmful to the whole polution thingy then 100+ cars put together. but you'll never see them slap a cat one one :rofl:

go set your car on fire again :lol:

I tried but I ran outa matches :x

they used to just send cars to the crusher instead of breaking them down into sellable parts, so you can't equate the content of cars with what they used to used before (unfortunately). i heard the argument that crushing cars today (because they don't hold their value like cars from the '60s and '70s) actually creates far more waste than hanging on to the older cars and running them without the 'smog' equipment that appears on later cars (imagine THAT retrofit), but most cars involved in accidents or left to rot aren't sent to the crusher anymore until they have been stripped of every usable part which would include the plastics and other new age materials.

i'd rather hang on to my classic and save another coupla them from the crusher than to have one of the newer cars. i can always update certain systems in the car (power production, braking, driver comfort) with newer materials, or restore them the way they rolled outta the factory.

cars are unfairly demonized. sit behind a bus in rush hour traffic to get a whiff of some truly dirty air. catalytic converters have to be on the car, so figure out some other way to increase power without removing them.
