I'm having some difficulty finding the appropriate combination of headers, lead pipe, catback setups for my 00 Cherokee. Anyone here running headers on this particular head? If so, what combination of products are you using.

Many Thanks!

IMO, with the '00 and up the converted to a 2-piece exhaust manifold on the XJ, so you're already gettting good flow. The cost of an aftermarket header just isn't worth it.

I agree, even on the earlier 4.0s you don't net much in terms of power gains. The only reason to replace the factory manifold is if it is cracked.
