Exhaust questions, installing a ZJ 4.0

I have an 88, 4.0, auto, 4x4.
We are putting in a 93 ZJ 4.0 & auto.


Headers - I'm going to go with APN, but it needs to be for the 93 ZJ (right?)

Catalytic converter - Need ideas (do I get one for 88 XJ or 93 ZJ?)

Cat Back - Dynomax has a great price, so maybe. Is there a website where you can hear different exhaust systems? And for this I get one for the 88 XJ?

Anyone?

Exhaust manifold for the 1993 GC (it is the same for the 91-99 cherokee, and I was told it could be used on Renix). You will probably have to have a new down pipe made, or possibly add some flexpipe between the down pipe and cat would make it work.

As for the cat, just go with a free-flow cat.

As for cat back, you probably want the 88 set so the pipes will be bent for that chassis.

And I don't know of a "sound" website for exhausts, but do a search on youtube, people post all kinds of videos there.

Who makes a good free flow cat?

As the Zj and Xj 4 litre engines are the same just use an Xj 4 litre exhaust system.

I've got good service from Magnaflow, they make ones specific for the XJ as well as universal fit.
