Cat Converter

[Mustang83]

Will a cat with broken insides cause sluggishness in the cars performance? Is there a way to fix them rather than purchase a new one? (Which I'm sure is againsed the law) But is there?

ya it can kill performance, but i don't know how to fix it without getting a new one. get one from a junk yard

Well you can do one of two things that i know of. First you can buy a new one, or you can take it off cut it open and gut the whole thing and weld it back together. But if you get caught doing this it is a 10,000 dollar fine on the spot, or atleast where im from it is. Either way you should look into the problem, cats that are getting stoped up will start causing major problems it not fixed in time. I had a 95' grand cherokee that had the same problem and i ended up just gutting the cat on it.

You dont have to cut the converter open to gut it. Ever heard of a tire iron? Just knock the guts out of it and weld it back up. '95 and older cars that came from the factory with cats just have a visual inspection for them. If you have atleast a housing then you pass that part of the inspection. Atleast thats how it is around here.

Well I guess maybe I'll try the tire Iron method first and see If I can knock the guts out that way before I open it up. I just had the car pass "Air care" (Thats what they call it up here in Canada) So I wont have to worry about it till next July. New cats are about 350$ up here.

Also, how important is the heat shield? It's making an annoying rattle. Is it cool to take it off?

Catco universal replacement high-flow cat = about $50. Perfectly legal to replace it.

How close is it to the floor board? What about gas lines? If its auto what about tranny lines. Alot of heat builds up in converters. I got a 3rd degree burn from one the other day. You can fix the heat sheild where it wont rattle if you want. Noisey heat sheilds are pretty common. A peice of thin metal strap exhaust hanger with the holes in it works pretty well, just run a small bolt thrue the holes to clamp it shut around the converter and heal sheild. Quick, easy, cheap fix that works, for a while atleast.

When I was still a young'un my Dad bought a new ranger in 92, heat shield fell of the cat in 2000 when I was moving out. Still drives it every day to work, cept now it has an S-trim on it, and he hasn't blown up so far.
