would a jdm itr headers fit my eg hatch b16a2..........? and size of the pipe is 2.5

 

yes it will fit

as for size im not sure if all are 2.5inch someone else has to answer that

 

can it make any differance...? like a lil hp or trq?

 

A lil hp and tq is right.
Make sure you have a 2.5 inlet for your cat.

 

how much of trq and hp will i gain? and also whats a fair price for the jdm itr headers?

 

New can be around 300, depending on if it still has the heatshields ect..
I'd expect 200ish for good condition used one.

And your hp/tq will be enough for you to think you notice something.
