Take your 2015–2021 Subaru WRX or STI to the next level with the ARK Performance N-II Single Exit Exhaust System, engineered for drivers who want a raw, aggressive sound and lightweight performance. Designed with a race-inspired single-exit layout, the N-II significantly reduces overall weight while improving exhaust flow, throttle response, and overall driving dynamics.

Built from high-quality T304 stainless steel, this system delivers exceptional durability and corrosion resistance for both street and track use. Featuring full 3 inch mandrel-bent piping and a large 4.5 inch exhaust tip, the N-II maximizes exhaust efficiency while giving your WRX a bold, aggressive rear profile. 

Unlike traditional dual-exit systems, the N-II is tuned for a louder, more aggressive exhaust note, making it ideal for enthusiasts who prefer a race-inspired tone with maximum presence. Its simplified, lightweight design helps reduce backpressure and enhance turbo performance, perfect for spirited driving or track builds.

The ARK N-II Exhaust is the perfect choice for WRX and STI owners looking for a track-style, lightweight exhaust system with an aggressive sound profile. Compared to dual-exit systems like the GRiP, the N-II offers a more raw driving experience with reduced weight and maximum exhaust flow.
