So, the exhaust manifolds on my -95 XJR are cracked. They sound awful, and look even worse. I have to order some new ones online, and I found this site:

Exhaust | Jaguar X300 - XJR | British Parts UK

Now, my question is, which one do I order?
Of course I need both the front and rear manifolds, but do I order the ones "with air injection and egr valve" or the ones without? What is the difference?

.. As a quick extra question, does anyone here have any experience with the mina exhaust system? And is the package one can order at their site the whole system from the manifolds to the back, or just the parts at the rear?
