HKS 32016-AH032 Silent Hi-Power Cat-Back Exhaust System

The HKS 32016-AH032 Silent Hi-Power Exhaust System is a race-inspired cat-back exhaust engineered for both turbocharged and naturally aspirated applications. Drawing from HKS's extensive endurance and GT racing experience in Japan, this system brings proven motorsport exhaust technology to street-driven vehicles.

The Hi-Power design features an offset muffler and optimized piping layout that reduces exhaust restriction by eliminating unnecessary bends, creating the straightest possible exhaust path. For turbocharged applications, the improved exhaust flow increases exhaust velocity for enhanced mid-range boost response and stronger high-RPM power output. Naturally aspirated engines also benefit as engine output levels increase.

This Silent Hi-Power variant incorporates HKS's proprietary Silent Chamber technology — a closed-end internal chamber that absorbs low-frequency cabin drone without disrupting exhaust gas flow or sacrificing performance. The result is a refined, sporty exhaust note at cruising speeds with an exhilarating tone under acceleration.
