XJ CRACKED MANIFOLD

There are lots of diff. options for manifolds and headers for 96-99 but so few for my 2000.whats the difference? can the 96-99 be modified to fit? Thanks for any input guys

I think they changed intake+exhaust port size to smaller size for '00.. I believe (don't hold me to it) that the 96-99 manifolds will BOLT up HOWEVER you will lose horsepower/torque because of the size mismatch of the 96-99 ports being larger. at least that's what I think I read.

I thought it would bolt up but i don't wanna be down on power for sure has anyone done this before?

running a header with larger ports won't really hurt power, at all. there might be a small bit of turbulance on port exit, but not enough to ever effect power in a negative way.
