2002 2.5RS
Exhaust: Stromung Catback
CAI: Ganzflow
Headers: Borla - Arrive the 22nd
I dont really know what gains these provided, I dont really remember what a RS drives like stock. The Stromung sounds good when its warmed up, when its not, for some reason its rattling against my rear diff even with Kartboy Hangers. I don't feel that I've lost any lowend torque, but I gained some power in the higher revs. With a Ganzflow CAI, K&N Panel Filter, Borla Headers, trackpipe, Stromung Catback, LW Crank Pulley, Exedy clutch and 13lb flywheel, and about 100lbs removed; I beat a stock WRX to 75 without launching.
