So what do you do? Stand behind it while its on and take whiffs?

I have never smelled it on mine.

 

i run a hfc... if i need more hp i'll get bigger cams or a bigger turbo

 

By running a HFC aren't you being legal and helping the environment?



All you people who are saying putting a HFC on your car is being PC are being silly. Just because volcanoes pollute the air doesn't mean you shouldn't put a HFC on your car. I can't stop a jetliner from taking off, but I CAN put a HFC on my car. It seems many of you aren't familiar with a concept known as the greater good

 

I guess you don't understand the meaning of usually. It means not all the time. Yes, I admit that comment was childish and I already said it was more for shock value than anything.

I notice how you side stepped the legality of replacing a functioning cat with an aftermarket cat. From a legal stand point it's no better than a test pipe.

I have the Helix HFC and that happens to be the one that made a whopping 5hp over stock. So, I guess one of the cats on your best of list doesn't meet my power gain expectations.

Regarding your SARD cat, Where can you find those readily available in the US? I looked and I couldn't find any that weren't ridiculously priced due to importing them and then had to wait months to get it. Now I know I said it wasn't about money but, there is a limit on what I'm willing to pay for something when there are alternatives that are supposed to be just as good.

I know your not talking about racecars. I'm just saying there are other sources of much more pollution than a small percentage of streetcars without cats.

Can you prove no cat is considerably worse on a well tuned car? I don't run into too many traffic jams around here so I'm not really concerned on that front.

But hey, don't worry if I don't see an appreciable power gain from no cat I'll go back to HFC.

Edit: My Helix HFC consistantly threw the po430 catalyst efficiency below threshold at least once a week after about 6 months of running. I nver got it with the stock cat. So, apparently it isn't as clean as stock.

 

Speaking of ignorance. You've lumped two totally different arguments into one. The discussion and debate over global warming is one thing. Whether or not mankind is capable of climate change is an entirely different debate. Whatever your opinion please understand these ongoing debates are independant of one another. The consensus in the scientific community is that yes, we are in fact in a period of global warming. There's scientific evidence to support that. In fact there's scientific evidence to support that the Earth's climate has done this before...millions of times.

The big debate among climatologists is whether or not mankind is capable of inducing climate change. There's politicians, activists, and complete a-hole nut jobs on either side of this one. It will be difficult to prove either way. At a minimum we're aware of the "potential". However as these moron fringe groups like A.L.F. burn down Hummer dealerships and sabatoge refineries countries like China, Brazil and India have zero regard for the environment. It's one thing to say "maybe we're making the ice caps melt", but it's another to watch an entire species of plants or animals go extinct due to unchecked commercial pollution into a local environment. If the tree huggers had any conviction they'd take their act to the developing nations. Instead they sport bumper stickers saying "think globally, act locally" and pick on easy U.S businesses already adhering to a litany of environmental regulations.
