It's not going to be a very noticeable difference. You'll feel it but it's not like :"Damn, this thing got quick". But hey, better than nothing.

and it doens't smell like rotten eggs becuase of the seconadary cat. that's the one that is not worth the bother of taking out.

your cat was probably melted and clogged... If you have a good working cat it won't make much of a difference.

It's not legal in any State to run a car (post 1974) without a CAT... and it most definately won't pass smog without a cat. Anyways... gains from removing the catalytic converters is not worth the hassle. The gains are minimal... -------------------- "It's ok to be naked girl... I'm an artist!"

But wouldn't that help your gas mileage a little bit? My buddy claims that since taking his out, he's picked up like 5 miles per gallon..

in his head maybe... the butt-meter is not a good way to tell anything. I'm running no-cat on my AE86 Hatch and it's not noticeable compared to my AE86 Coupe. The hatch pulled on the coupe with a cat by 1 and 1/2 cars, and again the same thing without a cat... only a bit louder. The exhaust flow does slightly increase, but it's not enough to make any noticeable difference. -------------------- "It's ok to be naked girl... I'm an artist!"

here in minnesota they took away the emission testing so haha but it's still illegal to not to have on but if they wanna argue no cops is goona know where the primary cat is. if he gives ya some hassle tell em to look under the car and there he'll find the secondary cat i like to call it the kitten haha.

A lot of the us UK guys are finding a de-cat pipe a really good and noticeable modification to have.
I personally, would say to go for it... just put the Catalyser back on for the emissions test when it comes to the time. -------------------- |

I was told by a guy who owns an emissions and safety testing place here in Utah, that if you are caught not having a cat on your car you could get up to a 25,000 dollar fine....sounds a bit extreme but if it were me I would just go with a high flow cat and save yourself the trouble. Like kwanza said unless your cat is currently clogged you won't notice much of a difference. The only way that you would is if you did an entire exhaust and not just 3 feet of it.

Made a huge diference to my car , the low down torque it gave made the car so much better driving around town, as raz sayed over here in the Uk everyone who has removed theres noticed a marked improvment, mind u the 3s-ge doesnt have a lot of low down torgue so any improvement will be felt better that with the engines u guys have

lol first i put the catback on my car, no power gains that i could feel then i put the down pipe and test pipe, which got rid of the 2 cats after the turbo. the car ran better, hit boost a little sooner, and made more top end power then i got rid of the damn cat that subaru put BEFORE the turbo that made a HUGE difference. boost came sooner, hit harder and 3rd gear wasnt a girlie gear anymore. best exhaust on a boosted car is no exhaust, after the turbo that is. -------------------- 1994 Celica GT4 WRC Edition
