I live in Europe and im going to buy my Apexi N1 from the JDM land! cause its more worthit for me. But I have a few questions. PLEASE no dont buy or very loud etc etc answers!

I just entered the Japanese Apexi site and saw that the N1 Muffler for ITR partno is
162-h003 . Its different from the US site . Is this normal cause its from a different country?

Also in the Japanese site its listed as N1 Muffler not N1 cat-back system ? Is this just the muffler(rear section) or the cat-back? Price is rather cheap too! The thing is that all exhausts are marked as Muffler! Like Hayabusa Muffler, Gt-Spec Muffler etc etc.

What do u you think guys?

 

part # is different because its a different part.
the piping length will be different between japan and us.
price looks right for cat back.

 

US has longer cats. so the catbacks arre shorter....buy a cat or a straight pipe from Japan too
