I bet neither of you have either flipped the dog bones, replaced them with polys, OR checked the condition of the lower motor/trans mounts.
If you have, then I suggest trying to shove that header in the crossover better, because the only issue I've ever had with any set was when I had to give some Imp SS AC lines some love to clearance the front header, fans were not in the way whatsoever.
My mounts are new just had the motor out.. Thanks though. And it's not a crossover issue the middle outlet off the engine is too long before it curves. I have an 04. Not sure what year yours is.
