I dont want to have to take it to some just to have them tell me it is. It's not giving off that bad smell like alot of stopped up catalytic converters do, but my car is a 1983 Cutlass Supreme and It has never been changed. Any help would be greatly appreciated.

the easiest way to figure this one out is to tap on it, sort of like beating on somebodys door when they wont answer, with your hand or a hammer. the sound should be almost hollow for a new converter, and dull, heavy for a plugged converter. you can usually feel that it is plugged up when you hit it with your hand, it will feel heavy. hope this helps p.s. if it is original to your 83 i would bet my next paycheck it is plugged up

If your car has 100K or more it would be a good idea to chang eit, especially if you have used high grade gas all the time. I changed out one on my F-150 and it weighed 50 pounds... it was 90% clogged. Get a universal highflow off of ebay for like $50

if it ain't broke -- don't fix it .... if your ride is going like okay then don't worry and be happy that you are not having to buy expensive new parts If you want to know for sure then you must go to a muffler shop and get the car tested for good/bad cat. converter ..

The downstream o2 sensor monitors the cat. Sometimes the 420 or 421 code is the o2 and not the cat.

if its stopped up then it will glow red and make your floorboard sweat and also you will lose power.
