GReddy Revolution RS Catback Exhaust for 2002-2007 Subaru WRX/STI
The GReddy Revolution RS Exhaust system is engineered to enhance performance and sound for the 2002-2007 Subaru WRX and STI. Featuring a full 76mm (3.0 inch) diameter non-tapered piping design, this catback exhaust reduces back pressure and turbo lag, resulting in increased throttle response and horsepower. Constructed from high-quality TIG-welded 304 stainless steel, it offers durability and a lightweight design without compromising strength.
This system includes a resonator to refine sound quality, producing an aggressive yet refined exhaust note measured at 102 dB(a). Dyno tests demonstrate gains of approximately 8 horsepower and 6 ft-lbs of torque on a completely stock vehicle, with potential for further improvements when combined with other aftermarket modifications and tuning.
