i recently gutted my cat and i normally get around 350 to a tank, well, since the gutting, i have 350 and still an eight of a tank left. Oh boy, gonna make it to 400!

 

It the car any louder?

 

Cats are on the car for the environment. Please put in a new one. There are other ways to get better mileage.

 

Justin, normally the catalytic shouldn't hurt the gas mileage on a NA car... Perhaps yours was going bad (impeding the exhaust flow)...

Aside from probably losing low end torque... it literally "sticks" and is bad for the environment and us...

Time to save for a RT catalytic or the likes...

 

What do you mean it "sticks"?

I recently failed my NYS emissions inspection, I suppose it's because of the cat since my NOx readings were above the limit. I still get like 190 miles per tank of gas, and I figured the problems are related. The mechanic told me it's the cat (referring to me failing the inspection). So is Chunger right? The cat doesn't hurt gas milage on an N/A car? I'm totally stock in terms of performance... My car feels very dead though, poor gas milage, strange smells when starting the car up... etc.. Is it clogged?

 

also it is ccheaper

 

I can save a bundle on gas and beat some Acura off the road by disabling all the emmisions control stuff on my car. My kids won't need to breathe when they grow up. Let's pull all those scrubbers off the smokestacks too so we can save 20 cents on our next purchase of hand cleaner. My electricity bill would be a whole lot lower too if we just let the power company dump the nuclear waste out the back door of the powerplant.

err ok

 

I think BobMax has some other issues bothering him and this was an easy way to vent

 

Yes. And all emission controls decrease your mileage not by too much though,.

 

I hear if you pull the seats out and cut the top off
your gas mileage will shoot through the roof. Of course gutting the cat will increase your gas mileage. I may be going out on a limb here but, part of the challenge is improving performance while being at least semi-responsible. This approach can be controversial, as it requires thinking.
If you really want to save money why don't you just leave the gas station without paying. That's just as illegal and the fine is a lot less.
Try a high flow CAT.

eventually man will adjust to be able to breathe more and more levels of CaRbon Dioxide, dont worry about your kids bill, maybe the next generation of humans will have gills...
that would be cool.

 

Damn 190 miles per tank? Thats horrible. It does sound like your car is cloged up, this whould explain the roten egg smell upon start up{Sulfer} and it would also explain why you failed emissions. A easy test of your cat is to crawl underneath your car {when it's cold!} and bang the cat with your fist and listen closely, if you hear things rattling it meens your cat is cloged up. If you don't hear anything I still suspect a problem with your cat. I say buy a car sound cat from WSP .

 

since the cat is no longer doing its job, and there is an o2 sensor behind it, did you get a check engine light?

 

Guys...I think bobmax was being sarcastic.

 

Yeah actually I was thinking of using those nuclear waste rods as home decorations in my front yard.
