00-01 After Market Exhaust Manifold
So Im looking around the market recently for another XJ. 00-01 seem to have the most saturation in my area for clean XJs. Im trying to do some planning ahead for a Clearwater or Alabama cylinder head and manifold swap (two birds one stone) as Im kinda OCD and the stock 0331 is going to nag me.
I recently discovered these model years dont have some of the fun things my 98 has access too. Are there no aftermarket manifolds for this cylinder head? I see the 0331 manifolds are a two piece set whereas my 98 is a solid piece which I prefer. Are the 00-01 already at peak flow? Do they flow better or worse than the previous years?

The 0331 head does not flow as good as old heads here a link that talks about it, https://www.enginebuildermag.com/200...ylinder-heads/
