  There is a pulse air plug that connects to the converter, should be plugged after converter is removed. The pulse air is the emission system.

You can take it out, replace it with some 2" straight tubing, here is a picture:

By federal law you are not supposed to replace it with a straight pipe and you will probably have a hard time finding a sho that will do it for you. But yes you can replace it without any performance problems. You could also take it off and hollow it out.

My muffler shop has a sign that says,

So if you go in there with your cat already out, do they have to put one in??

Most exhaust shops probably won't touch an exhaust if the cat is removed. They don't want to chance the huge fine.

My 86 Eagle wagon seemed to be gasping for breath, like someone had shoved a sock in the air cleaner. Did all the usual stuff to no avail. Recalled someone saying the converter might be plugged up so I unbolted it and while still under the car I looked through the converter and it was open all the way through. Before putting it back on I crawled out and for some unknown reason I stood the converter up on end. A whole bunch of stuff rattled around in there and looking thru it again I could see it was now plugged up. The guts of the infernal thing had begun to fall apart and at idle would just sit in the bottom but with increased rpm would blow back and plug the pipe. A few jabs with a long chisel and the offending pieces all fell out. Put the otherwise solid converter back on and the car runs great.

I think mine has a resonator where the catalytic converter would normally be. It's cylindrical with smoothly tapered ends, looks like aluminum (aluminized steel?) and makes a hollow ring when I tap on it. It came this way from the previous owner, who lived in Alberta. There were no air lines or pulse air valves. Ontario does not test vehicles as old as my eagle.

Up in Canada we didn't have catalytic converters on our Eagles. Can't remember how they did it but they were able to skirt around that some how.

When I got my '88 Eagle wagon, last year, the mechanic (who I know) let me slide through PA Inspection with a blown-thru cat. It ran real nice, since there wasn't any back-pressure to the exhaust system.

But, this year, I had to get one. It cost me $135.00 for a universal cat though Advanced Auto Parts. It doesn't run bad. but, there is a difference when you stomp on the pedal. Seems like it runs slower, due to back-pressure.

Wish I could run a burned out Cherry Bomb thru a side pipe.

 PR,
     Most like because Eagles were classed as trucks or MPVs.

Yeah I too called my local muffler shop(s) And everyone said I had to put a cat converter back on. Aeeee, no. So I got a few friends who know auto pretty good, were just gonna weld some pipe together and put a new muffler on.  :censored:,
