Well it depends on the model, but they are all mostly the same, and not to hard to do. Your only looking at about 4 bolts, and 2 nuts. There are 2 upper bolts (13mm) 2 rear bolts, with nuts on the back side (also 13mm, but the nuts are usually 12mm) Then 2 more nuts in the middle, supporting the exhaust to a bracket. You will need new seals for the new exhaust, and I also highly recommend getting 2 new upper bolts. One side can be easier then the other, because it has a 'butt-joint' where it connects to the rear portion of the exhaust, the other side has a 'slide-joint', and usually requires the other side to be loosed to help remove. Also remember that there are 2 oxygen sensors that will need to be unplugged and transfered over to the new exhaust. (22mm) I would start with removing the 2 upper bolts, next remove the 2 rear bolts and nuts. Then remove the side nuts last while supporting the exhaust. then the exhaust can be removed down at the rear and out. Good luck, anymore questions....just ask.

You did not state as to the year,make and model of the car as well as the engine size. I am a member of IATN and the majority of there fixes was related to someone installing an AFTER MARKET converter. There is a big difference. I strongly suggest that you go to a repair shop with the proper equipment as well as a very good tech to diagnosis the problem. You could replace parts and never fix the problem.jd1709
It is possible but highly unlikely as a catalytic converter should NEVER go bad unless something causes it. If you have a check engine light "ON" then I would have someone with the knowledge and equipment to diagnosis it for you. It will save you alot of money. Either a very rich or lean condition will cause a converter to glow red and seem stopped up.jd1709
the above answer is completely wrong
as in all car parts they wear out
a cat will clog up and/or become poisoned
if it is clogged it will stop exhaust escaping properly therefore makeing engine suffocate
any exhaust shop can replace cat converter
and any handy man can also replace cat converter

∙ 14y agoI don't know. The "check engine" light on my '99 2.0L came on at 77,000 miles. OBD II says the cat is bad (and so is the cost.) I think it should last longer.
