I just gatted my cat on my 88 vert. It sounds much deeper, and has a lil nice backfire at high RPM's. But, is it normal for the car to smoke alot when the cat is gutted? It puffs out alot of white smoke the first minute started and when revved. The car has 165,xxx miles on it. Is this normal or is this a sign of my engine going?

 

Well I know that a lot of white smoke means your coolant seals are going bad. Did it smoke before you gutted it?

 

Well it smoked a little, it was not noticeable.

 

Gutting the cat probally just let all the smoke that wasnt able to get out get out much easier.

 

That's what it sounds like to me, and gutting cats is a pretty worthless mod..

 

bah! you gain some hp and some flames if you are really cool.

 

if you have a big turbo like my girlfriends - turbonetics t76, gutting her cat was the best mod we ever did. Here in australia cops *** rape you if they catch you with no cat, so best thing was to gut the cat so it looked like it was still there.

How are you sufficiently supposed to flow 400+rwhp with a cat there :P

 

that's what i'm talkin about! do you know how much you'll get fined if a cop sees that there is NO cat there?

gut cat, still stink, and just pay someone a few extra dollars a year then it's all good.

 

its a 11 thousand dollar fine if you have no cat...

my girlfriend got the fine, but they ripped it up... i dont know how a cop could seriously issue it for real!!! Scared the **** out of her, she cried the whole time the cop was defecting her car (series 6 - FD). Thank the lord they let her off the cat fine.

Haha damn thats crazy!..Pretty sad too, 11k fine?! damn! geez..but yeha thnx for the info guys.

 

How hard could it be to fab up a realistic looking cat that would be welded onto the outside of like the RB midpipe? I would imagine with a little bit of welding you could make a pretty decent looking cat that was completely non-functional.

my blue 87 smokes liek crazy after i start it up sumtimes but playing around with the TPS and variable resistor fixes it then its no smoke and flames.

btw im running a 2.25" straight pipe and my car has 202K miles
