Help factory catalytic con? Options

[bdog_v]

Well I am trying to install a new exhaust on my 94 celica Gt model and when I pulled the downpipe off the exhaust manifold I was surprised to see honey comb material in the exhaust manifold, like you would see in a catalytic converter????? Is the cat. located right next to the exhaust manifold on this car? If not what is this???? I don't have a cat anywhere else in my exhaust system.

-If this is the cat. I want it gone. Can you just punch out the honeycomb material and run it hollow or do you need to replace the cat. *if it is the cat.* with a straight pipe?????

-I don't have the heat shield off yet so I am not aware of how this is bolted together any ideas???? Thanks....

did you have it inspected afterwards? i'm just hoping mine will still pass with that one punched out...

Yes I did. Here in WV, if your OBD1, they don't check emitions. They make sure you have a cat, but other than that, they don't care. I'm not sure about other states.

-What I would really like to see is a picture of the cat. that is located by the exhaust manifold, seperated from the rest of the exhaust so I can see what it would take to make a pipe to fit in its place..... Anyone have any pics of this piece????? Taken out of the vehicle..... THanks....

I wanted to do this after I took mine apart. I think you'll just have to open it up for the measurements. It's definately possible. I didn't do it because I was just to lazy to mess with it, and it was going to take another day of work because I didn't have a car to drive. I would have had to wate on a ride so I could get the parts I needed for it. I would really recommend doing this if your going to put a pipe in there.
