Hi, I just purchased an 82 Iroc, can anyone tell me if it came from factory with a cayalyctic converter..? I am new to the 3rd gen. camaro, and will be on here quite a bit now..... hope to get some tips, and pointers from you experts.... I will be posting pics as soon as I get some...
THANKS, CHAD !!

 

First it is not a iroc, iroc was 85-92. You just bought a 82 z28 more than likely. Second im pretty sure it came stock with a cat and also with a smog system

 

Welcome to TGO, magikstik.

Yes, the car was equipped with an OE cat.

The IROC was around from 85 to 90.

Eh I was close. I got a 84 z28 so I'm not familiar with irocs that much

 

in the U.S. at least,'82 did have catalytic converter-on
'82s,carb ones at least, it was the old style"pellet bed"
type-'83s were updated to a honeycomb style,the
reason '83 had slightly higher HP rating than '82.

 

If you want or have to run a cat a new high flow cat would be leaps and bounds better than the stock pellet style. High flow cats are cheap.

 

Thanks for the info guys! I look foreward to this car.. It is a pro-street car, and my first race car.... Pics are to follow...

 

CFI got the honeycomb style Cat in 82

 

So you want to run a cat and or cats on a Pro Street car? What engine is in it and what is the exhasut set up like right now?

 

well not really... I need it for inspection... maybe... . it has plain aftermarket duals.... haven't gotten the car as of yet, it is in transit...

 

I just changed the original catalytic converter on my Firebird and replaced it with an aftermarket high flow cat. Much, much cheaper than buying an OEM cat and a much better product. You'll need a chisel for one end. The other end is bolted. Neither end is welded unless some idiot PO decided to be really stupid.

I also used a disposable cutting wheel on my drill since I didn't have an exhaust cutting tool for my cheapo electric impact wrench. If you have a reversible drill, set it so the direction of the spin on the cutting wheel will spin away from your face if it slips. You don't want to change your nickname to "scar face."

If you have the correct power tool or grinder, use it instead. Be careful that you just cut the cat pipe and don't go deep enough to cut into the exhaust pipe. That's why you need a chisel. Make several cuts down the cat pipe. Then chisel if off.

The bolted end should be easy to remove after applying some PB Blaster. Also, the old cat is worth enough money to more than pay for a trip to any metal recycler. When I installed the new cat, I used exhaust putty (any auto parts store) on each end just to be sure nothing leaked. No doubt, someone will jump in and say you don't need it on the bolted end - they are right, but I'm pretty **** about preventing the inhalation of carbon monoxide and it won't hurt to do it.

That's how I did it. There may be some exhaust experts jump in and offer some other better suggestions. I'm the first to admit I'm not a very good mechanic, but found the cat replacement to be a fairly easy job. I just wish I had a car lift and garage rather than using a trolley jack and jack stands on the street in front of my house. On the other hand, these cars are fairly easy to work on in just about anyplace. Owning an older car means doing a lot of the work yourself or having a big pocket full of cash to pay someone else do it.

A new high flow cat is likely to add a little power boost to the engine. What a deal, your car will be smog legal and have more power and it is cheap to do it.

 

Thanks for the info... I'm not sure it has the cat on it, beings it is pro-street.... I will be putting one on if it doesn't have one, for inspection at least... It will be here monday morning.... so i will post pics as soon as I can... Thanks!!

 

I look forward to seeing the pics of your new toy.
