Has anyone replaced their header and precats on an 01 XJ? I've got a 4.9L stroker and I want to get a little more performance out of it while doing something with the darn precats on the factory header. The things are super restrictive. It seems like all the aftermarket headers out there are for 99 and before. Might try some Pacesetter headers because they have holes for the O2 sensors if I can get it to work. Thanks guys.
