Topic: Exhaust Choices - JDM WRX same as USDM 2.5 RS?

[doubtless]

So question is in the topic... but it's a 2 parter!

We know that to be interested in a new downpipe and exhaust combo we need some form of tuning for the car. We also that the JDM downpipes will only fit with JDM exhausts, and that a US downpipe will mate up, and needs a US exhaust... With this in mind if we're shopping, we SHOULD be looking at what's available for the 2.5rs, am I right? I assume these are different between the old GC chassis and the GD's?

Second part! IF one were looking for a new catback, what manufacturers should a person be looking through?

I'll edit this post with links to manufacturer pages for information based on responses, and then SubieRoo or a mod, could you tack this into the JDM FAQ thread in the Tech Discussion forum?

I posted this elsewhere but you need a full JDM TBE or a full USDM TBE.  No mixing and matching.  One of the hangers doesn't line up on the USDM TBE so you can get it moved, use a USDM rear crossmember or do nothing at all.  It's not important.

Don't look at 2.5RS exhausts, look at WRX/STI exhausts.  If you search, you'll find a million other threads for exhaust recommendations so I recommend doing that first.

2.5RS exhausts are for N/A cars, so they are meeting up to where the headers end, not where the end of the up-pipe, turbo, downpipe detour in a turbo Subaru ends up.

Clear?

So by looking at WRX/STI exhausts, are you saying the GD's bits will fit onto the GC's without issue?

Right, I feel silly now for asking that one.

I have a complete stock STI TBE on my 1999 RS.  One of the rear hangers won't line up for you unless you use a USDM rear crossmember (and I did) but that hanger isn't important.

Perfect, thanks for answering! Knew you'd be one of the first with an answer

No need to feel silly, just answer it for the next person.
