What is the main benefit of a cat-back exhaust system?

A cat-back exhaust system replaces the factory exhaust from the catalytic converter back. This typically results in improved exhaust flow, a more aggressive engine sound, and can contribute to a slight increase in engine performance by reducing backpressure.

What material is the GReddy Evolution GT exhaust made from?

This GReddy Evolution GT cat-back exhaust system is constructed from polished 304 stainless steel. This material is chosen for its strength, resistance to corrosion, and its ability to withstand high temperatures.

Does this exhaust system come with new gaskets or hardware?

This cat-back exhaust system is designed as a direct bolt-on replacement for the factory exhaust. While it is designed to fit the factory mounting points, it is recommended to consult the manufacturer's installation instructions or contact GReddy support to confirm if any specific hardware or gaskets are included or recommended for installation.

Product Details

Constructed from polished 304 stainless steel, this GReddy Evolution GT cat-back exhaust system is built to last on your 2009-2014 Nissan 370Z. This system replaces the factory exhaust from the catalytic converters back, offering a significant upgrade in both sound and exhaust flow. The dual muffler design and large, straight-through mufflers are key to its performance characteristics, helping to reduce backpressure and allow your engine to breathe more freely.

The Evolution GT system is designed to provide a more aggressive and sporty exhaust note that complements the 370Z's performance. GReddy uses advanced muffler packing technology to balance sound suppression with minimal flow restriction. The polished 304 stainless steel construction not only looks good under the car but also resists corrosion, ensuring longevity even in varied driving conditions. This cat-back system is a popular choice for 370Z owners looking to enhance their vehicle's auditory and performance profile.

Installation involves removing the stock exhaust components and bolting on the new GReddy system. The dual 4-inch polished stainless steel tips provide a clean, performance-oriented finish. This cat-back exhaust is a direct fit for the specified 370Z models, meaning it's designed to bolt up to the factory catalytic converters without requiring extensive modifications.
