Subaru WRX: On the portable dyno with upgraded catback exhaust at Bimmer fest - English Town NJ

Caught this Subaru WRX on the dyno at Bimmer fest in English Town New Jersey last year. Bimmer fest may be only about BMW's but all are welcome here, It's all about the fun and getting together. This WRX has an upgraded cat back exhaust system plus more, that's as much as I know, sounds pretty sweet though.
