Default JDM vs USDM vs NZDM/AuDM

Hey guys


I have a 2001 WRX JDM, and am looking at upgrading the Downpipe. As far as I know, the USDM and NZDM V7 (bugeye) wrxs have a cat in upipe and downpipe and the JDM only has one in the Downpipe.



Also, as far as I am aware the JDM downpipe is short compared to the USDM downpipes and the midpipes on the JDM is longer compared to USDM.



My question is, all I have on the vehicle is an STI Genome axelback. If I am looking to upgrade the Downpipe, where do I begin as trying to find JDM parts seems extremely hard.



I was looking at these downpipes https://www.google.com/search?q=invi...active&ssui=on



But after messaging them they told me they won’t fit my JDM WRX as they told me they are only for NZ new/Australian vehicles.



What to do? Can these be modified easily to fit? Should I just replace the whole exhaust set up with a US Turboback system? It seems like there is a lot of great US aftermarket exhaust systems, but not sure what to do in my case.



Thanks!
