would headers from HX engine fit and work with non HX engine?
it will fit but will not help with the mpg. the hx has an egr system that is designed to recirculate exhaust with unburned fuel into the intake so that it can be burned. thats what makes the hx so mpg friendly. the exhaust manifold is identical to the dx version.
The hx has the cat on the header - like the d16y7
Im willing to bet that the header your looking at is for a d16z6 or a y8, which would have the cat after the header.
Without replacing the cat with a corresponding one from an ej8 (ex) you will throw the code for 2ndary O2 and come up short connecting to the Bpipe
