HKS Hi-Power / Hiper Catback Exhaust System 2-Seater Coupe 3106-EX003
The HKS Hi-Power is one of the best flowing and best sounding exhausts for the 300ZX, and is still of very high quality despite the low price. Hi-Power Exhaust systems incorporate a race inspired angle mounted stainless steel muffler and piping design for greater flow and higher-RPM power gains, which provides a less restrictive path for exhaust gasses compared to many exhaust systems, which mimic the stock exhaust with two ~90° bends. The large, angled mufflers compliment cars with a low, wide, aggressive stance. You can expect a 20HP gain on a Twin Turbo, and a 10HP gain on Non-Turbos (Coupe Only). The HKS Hi-Power will NOT fit on a 2+2 model.
