The GReddy Revolution RS for the (GDB) 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 8lbs 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 fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.

The Supreme SP for the 4th generation ND Mazda Miata was designed and engineered specifically to suit the USA spec 2.0l Skyactiv-G engine combination. Unique to this application is the availability of either the pre-resonated axle-back muffler system, for maximum sound control with enhanced flow. Or there is also a full cat-back system, that includes a dual resonated mid-pipe for even more performance and a sportier sound. The full system showed power increase throughout the RPM band, with maximum gains, of 13hp/8ft-lbs, as low as 3500rpm. Both options use the same unique rear section with dual 82mm GReddy exhaust tips. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty
