Product Description

The HKS 32003-KN002 Hi-Power Catback Exhaust is a performance exhaust system engineered for the 1989-1994 Nissan 240SX S13 chassis. Designed to improve exhaust gas flow over the stock system, the Hi-Power exhaust incorporates a race-inspired offset muffler and mandrel-bent piping layout for reduced backpressure and enhanced engine breathing.

The single rear outlet delivers a classic performance look while delivering sound and flow improvements over the factory system.
