Our system on the other hand, produces more torque through the midrange than most exhausts on the market, while retaining higher than average horsepower gains. Many other companies go oversized on the rear circuits to accomplish this goal of keeping flow up in a divided exhaust, however, the overall midrange torque suffers and the horsepower is no higher than a system with a smaller terminal circuit diameter. Starting from a goal of matching the flow of exhaust through the 3" section and into the 2" sections, the division of exhaust is accomplished with a larger diameter 2.25" Y section in the midpipe, which takes the position of highest friction in the catback exhaust and ensures a proper division of exhaust gas flow without inducing restriction. The main functional elements of this catback exhaust are its matched flow dynamic from the 3" diameter resonated main circuit into the 2" diameter secondary circuits (the dual circuits of the rear of the exhaust).
That standard is achieved through a number of innovative design cues that have made Nameless Performance the top name in Subaru aftermarket exhaust development and engineering.

In testing on the EJ series engine, this catback has shown midrange gains of +32ft lb of torque and +22hp at the wheels above and beyond a standard off-the-shelf Stage 1 tune. Following closely in the footsteps of the '11-'14 WRX/STi Sedan Catback, with a number of improvements and changes to fit perfectly on your '15 WRX with the DIT engine or your '15 STi using the tried and true standard EJ series engine.
