90 N/A. Bought the car with a cheap ebay exhaust. Car was so loud and dronney, that you could barely drive it. Bought this exhaust and installed it myself. What a difference. It's definitely quiet, would say it had an enhanced stock sound. It makes driving the car a pleasure.

Installed on my 91' N/A. Impressed with quality. Fitment was spot on. The tips don't stick out past the bumper, which I like. Driving around town at low rpm, its pretty quiet. But once you get on the hwy it purr's. Has a nice refined sound to it, no drown at all. Very impressed. I questioned the price at first, but after having on the car, well worth.

I installed this exhaust on a 1990 300ZX and i must say, the tone of this exhaust is very pleasant on the ears! At idle it purrs, and on open throttle it roars, while still not being offensive to anyone's ears. This is a nice low profile exhaust. The fitment is spot on! NOTHING needed to be modified to make this exhaust fit.

Just installed on my 1990 300ZX. AWESOME!!! Great quality exhaust for a great price. Perfect fit, and nice deep AMAZING sound. It took me months to find it, as several places advertise it at a little lower price, but NONE have it in stock. It was worth the wait! Beautiful system. ZX owners, I highly recommend this exhaust!
