Valvetronic Designs Nissan Z Valved Sport Exhaust System

The Nissan 400Z brings back the spirit of the Z car with its new twin turbocharged V6,. While the platform delivers strong performance, the factory exhaust system is heavily restricted with small piping that mutes much of the car’s potential sound. At Valvetronic Designs we knew exactly how to approach this car, using our engineering experience to create an exhaust configuration that delivers the raw, motorsport inspired sound this car deserves.

Purpose-Driven Engineering

The system is constructed from premium T304 stainless steel and designed around a center merge crossover mid pipe that optimizes flow and harmonics before feeding into the valved rear section. With the valves closed the Z remains quiet and composed, perfect for cruising or late night drives. With the valves open the car transforms completely, delivering an unfiltered and aggressive tone that matches the performance heritage of the Z badge. Larger piping size increases efficiency, reduces back pressure, and sharpens response, while a set of 5 inch double wall tips give the rear end a striking finish.
