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.

Will this fit on a 1990 300zx base 2 seater non turbo ?
- Eric Ibarra
Match with nissan 300zx 1996 NA 2 seater
This would not fit the 96, as the flanges at the catalytic converters are clocked differently on the 96.
What internal diameter is this? 2.5" or 2.25"?
Hi Bogdan, the inner diameter is 62mm
