Product Description

The HKS Hi-Power is one of the perfect flowing and perfect sounding exhausts for the 300ZX and is still of outstanding 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 gives 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).

It’s so sexy

Got a good price on them brand new, installation went smooth, and it gives my NA Z the right amount of grumble without it being too loud.

Sounds great

Ordered an hks catback exhaust for my 300zx z32, and had it installed. Exhaust sounds great, nice deep tone. This is my 3rd set of hks exhaust and won’t get any other brand exhaust. Shipping was fast and I received it in no time.
