I have a 2001 Nissan Quest GLE (88,000 miles) with a 3.3 V-6 engine and equipped with California emissions. With this set up both the exhaust manifolds and front catalytic convertor are 1 piece. I have a leaky rear manifold and in order to repair the manifold I must remove it. I need to know how to remove and replace the this manifold.

I'm sure it is difficult but I'm sure it's leaking somewhere under the heat shield and must be removed. None of the reference books show te CA model wit the cat welded to the fron manifold. Your indicated reference for purchase doesn't llist any exhaust manifolds only gaskets. Thanks for your time and if you run across a reference showing the cat welded to the front exhaust manifold please let me know! :)

Even I too face similar issue.
One of my friend told me to buy new one.
What is your opinion, whether should I change the old one?
Looking forward for your opinion.

And If I have to buy new one, If you have any new place recommendation, let me know!
