Aftermarket Cat Converter

[GrandJP]

Guy's,

Any idea where to get a replacement catalytic converter for a 97 ZJ aside from the stealership? and how much did you spend if you have upgraded yours before?

Mine has most likely desintegrated from rust??? as it is making this loud noise and vibration inside the cat everytime i accelerate or idle in drive.
If i hit it with a rubber mallet, it makes this sound like pieces of metals are all over the place.

cheers,
Jetty

Any decent muffler shop will be able to help you out.
They are not cheap wherever you go to get one though

Where are you located Grand JP?

I realized that today, zzzz. Carline quoted me this afternoon for $450 fitted for a universal one. Jeep-specific one would cost me $1400, he said.

Any experiences from other people or with their Jeep models?

My GC is 7 yrs. old and always hi-octane fuel everytime. Is this a normal life span for a cat conv?

Cpage66, i'm from Sydney (south).

GrandJP for $450 you should be able to get a high flow stainless steel jobbie. Give Liverpool Exhaust a call, that's where i got my exhaust done and so did Cpage. He recommended them to me and i'm happy with their price and the job that they did.

Inside a cat there's a ceramic block, and if broken apart will sound exactly like you're describing.
It's wierd because they rely on heat to function as intended but can break apart if the exhaust temperature gets too hot. It can also break apart if it cops a big enough hit offraod.
Then it could just be one of those things that happens for no apparent reason, call it unlucky.
Here's some info on them

Yeah Grand, what Wild said...The boyz out at Liverpool are rice racers but they work on anything and everything. They have a topnotch outfit going there...I recommend them for any work like that.

Here's a shot of the work they did for me...
