Catalitic Converter Issue

[dylanr91]

My Catalitic Converter is in need of a replacement as according to a garage in town. Anyone have a way to get the darned thing off and replace it?

Thanks

im not sure exactly what vehicle you have with what engine, but being a chrysler, it is either bolted or welded solid (no clamps). Depending on vehicle, the y-pipe from the exhaust manifold to the converter may be one unit. More than likely you will need a torch and some air tools.

If you are looking at getting a direct replacement, the unit is the y-pipe from the manifold down to the end of the converter. Dont qoute me, but I think the exhaust bolts are 15mm or 13mm Im not sure right off. The converter is clamped on to the exhaust pipe. This will take a torch, hammer and of course the proper saftey wear. It would be alot easier and safer if the vehicle was off the ground on a lift. No more than a muffler shop would cost to replace this piece (labor), I would refer you to take it to someone to do the repair.

the converter should be held on with exhaust clamps. Remove the exhaust clamps and beat the converter off the y-pipe, there is a tool for this (that will pull the pipe apart) but it is not a needed, ussually I will use my air hammer with a chisel bit to cut the pipe and remove it but you can also use a recipricating saw and cut a slot in the cat around the pipe (besur not to cut thru the exhaust pipe or the y-pipe) just thru the cat pipe, this should make it easier to remove ther cat.

I had to replace my muffler and I cut the pipe with a sawzall (recipricrocating saw). Cut it as close to the old CAT as you can so you don't cut the muffler or manifold pipe (as dksob indicated). If it's clamped, the bolts are likely to shear off anyway when you take it apart; you'll want to replace the clamps, and if you don't get an exact fit with the new CAT, use couplers with reducers to make it fit before clamping it all together.
