That subaru was probably stock with maybe a tune and exhaust. Those young kids claiming 425 at the wheels need to put down the crackpipe. Without major work on an STi you are not going to get 425 at the wheels from that thing. It's hard enough to get 325 at the wheels of those things let alone 425.

I owned one a few years back and had tune/full exhaust/intake and a decent set of tires and the best it went was 12.9@103 with a 1.8 60 ft. It made 270 to the wheels with those mods. A stock srt from a roll would do exactly what it did in that video to one with those mods.
