The Revolution RS for the GD Subaru WRX/STI features a full non-tapered 76mm (3”) diameter piping. The focused layout of the cat-back exhaust uses minimal bends to produces a cost-effective, light-weight system that saves 8 lbs over the stock system. Traditional GReddy RS styling positions a large resonator and the muffler and tip fashionably underneath the vehicle, while enhancing the profile body-lines perfectly. Dyno test have shown increase in 8hp and 6ft-lbs of torque on a completely stock vehicle, with the potential for additional gains with other aftermarket modifications and/or tuning.

Like all GReddy Revolution RS systems, the exhaust is made from fully hand-welded 304 Stainless-Steel and carries a Limited Lifetime Warranty.
