I don't think we can even generalize without a little more input.

I'm so glad you said this.

The speculation of WHP and WTQ is absolutely ridiculous.

Any suggestions where to go from here with modifications. I am interested more in reliability and longevity but would like some more performance as well.
Budget $2,000.00 for now

Downpipe, protune, done. You should have enough left over for sway bars.

tim finnegan · 06-25-2008, 10:55 AM

do you recommend a specific downpipe and sway bar set?

Hard to say. There are LOTS of downpipe choices. If you want to keep the SPT exhaust, a COBB downpipe would probably be best as it should fit because it will taper.

Sways, well, I dunno. 24mm front and rear would be good. Get endlinks, too, at least for the rear. But that's another thread.

I advise you to do some reading. Use that search function and you'll have a lot of choices on your plate.

any idea if putting in a cobb 3'' downpipe will require removal of the turbo?

NO downpipe should require the removal of the turbo as far as I know.

I dyno'd my 2004 twice, both totally stock and on the same dyno, and both of the maps were provided by Subaru. The first one was the stock map when I got it in 2003 and the second was offered for the CA 91 oct issues - knocking, etc. Both on GST's mustang dyno in the Bay Area:
