Hi-Power Cat-Back Exhaust

• 1995-1998 Nissan | 240SX

The HKS Hi-Power Cat-Back Exhaust for the 1995-1998 Nissan 240SX (S14) is the Hi-Power 409 series system - the louder, turbo-oriented counterpart to the HKS Sport (31013-BN001). An 85mm large-diameter center pipe with a straight-through race-inspired layout improves exhaust velocity for better mid-range boost response and high-RPM power, finished with a 120mm round tip. The muffler and tip are SUS304 stainless steel with SUH409 stainless used for the remaining piping.
