Exhaust Advice

[Huckh2o]

I tried to replace my catalytic converter on my 1993 16v 4dr 4x4 sidekick yesterday and ran into some problems. I was sheared off a the front stud in my exhaust manifold. I took it off to try to see if I could get the stud out and found the #4 cylinder was cracked most of the way around. at this point i'm ready to get the thorley headers from rock road.

I already bought the replacement CAT and silencer section that I would have needed to fit the stock 93 exhaust manifold. amazon links below.

CAT

Muffler

Now I'll need to return some parts... at least the cat.

Can someone who has the thorley headers recommend a cat that will join up to the silencer section I already have?

Thanks,

Todd
