Stromung for me, but the only reason I chose that over the Scoobysport is because the Stomung is a touch quieter. But I think thier HP gains are almost identical, and the duel-tip Stromung looks almost stock.
I think the Apex'i N-1 is a good application I haven't tried neither oneof the above mentioned soI can only speak of the N-1 great sound!, awesome response at Mid and High range Add a CAI, and Headers and you got yourself a Winner.:sunny:

What about Brullen! I have the "quiet" version. Nice, deep rumble.
When used with a Ganzflo intake a produces one fine sounding Subaru, and adds some performance!
Scoobysport, enough said. Great sound, great performance, non-rice(imho), and it comes with 25 year warrenty against corrosion. Its stainless and is hand made. Beat that.
I've only got the axle back, so can't comment on gains, but I really love the sound. just took a video clip today in case anybodies interested: http://home.attbi.com/~mcad10/stiex.mpg
stromung dual tip for me. i also go the axle back. nice tone and looks pretty much stock from the back. only problem is that it started rusting after 3 months. not that bad rusting, but the welds have a little rust on it.
