Exhaust Muffler Catback for Nissan 370Z (2009-2020)

High-Flow Stainless Catback Exhaust for 2009-2020 Nissan 370Z (VQ37VHR / Z34)

Replaces the restrictive factory exhaust system to lower backpressure, increase scavenging efficiency, and deliver a more aggressive exhaust note.

The Stock Z34 Exhaust Weakness

The factory Z34 exhaust system utilizes heavy, multi-chambered mufflers and crush-bent piping sections that prioritize quiet operation and mass-market comfort over optimal exhaust gas velocity. This OEM configuration introduces significant backpressure, which chokes the naturally aspirated VQ37VHR engine at higher RPMs. Furthermore, the restrictive Y-pipe and mid-pipe transitions create exhaust turbulence, generating heat soak and limiting both low-end torque and high-end horsepower production during aggressive driving scenarios.

The Engineering Solution

This catback system resolves factory flow limitations by utilizing 2.25-inch major piping constructed from premium T-304 stainless steel. Computerized mandrel bending ensures a consistent internal diameter throughout the exhaust path, eliminating pinch points and maintaining maximum exhaust gas velocity. By optimizing the cylinder scavenging effect, this system yields a dyno-proven output increase of 15 to 25 horsepower and vastly improved low-end torque. The CNC-machined, TIG-welded flanges resist warping under severe thermal stress and high pressures, ensuring a leak-free seal. The system terminates in dual 4.00-inch slanted and burnt exhaust tips that enhance the rear aesthetics while delivering a deep, aggressive resonance. Gaskets and hardware are included for a direct bolt-on installation.

Common Questions

Will this catback exhaust fit my 2016 Nissan 370Z?
Yes, this system is a direct bolt-on fit for all 2009-2020 Nissan 370Z (Z34) models equipped with the 3.7L VQ37VHR V6 engine, including Base, Touring, Sport, and Nismo trims.

What comes in the box with the exhaust system?
The kit includes the complete T-304 stainless steel catback exhaust assembly with dual 4.00-inch slanted and burnt tips, along with the gaskets and mounting hardware needed for installation.

What piping and tip sizes does this 370Z exhaust use?
It is built with 2.25-inch mandrel-bent T-304 stainless steel main piping and finishes in dual 4.00-inch slanted, burnt exhaust tips.

What kind of performance gains can I expect?
By replacing the restrictive factory crush-bent piping and multi-chambered mufflers with mandrel-bent 2.25-inch tubing, this system reduces backpressure and improves cylinder scavenging for a dyno-proven gain of 15 to 25 horsepower and stronger low-end torque.

Does installation require cutting or welding?
This is a direct bolt-on replacement with CNC-machined, TIG-welded flanges that mate up using the supplied gaskets and hardware.
