How to Upgrade Your Nissan 370z Exhaust System Yourself: from 330 to 350 Hp – Is It Worth It?

The Nissan 370Z is a beloved sports car known for its performance and sleek design. Many enthusiasts look to upgrade their exhaust systems to enhance power and sound. In this article, we will explore how to upgrade your Nissan 370Z exhaust system yourself, boosting horsepower from 330 to 350 HP, and discuss whether the upgrade is worth the investment.

Understanding the Stock Exhaust System

The stock exhaust system of the Nissan 370Z is designed to balance performance, sound, and emissions. However, it can be restrictive for those looking to maximize their vehicle’s potential. Understanding its components is crucial before making any upgrades.

  • Exhaust manifold
  • Catalytic converter
  • Muffler
  • Exhaust pipes

Benefits of Upgrading Your Exhaust System

Upgrading your exhaust system can provide several benefits, including increased horsepower, improved sound, and enhanced aesthetics. Here’s a closer look at these advantages:

  • Increased Horsepower: A performance exhaust system allows for better airflow, translating to more horsepower.
  • Improved Sound: Aftermarket exhausts can provide a deeper, more aggressive sound that many enthusiasts prefer.
  • Weight Reduction: Some aftermarket systems are lighter than stock, which can improve handling.
  • Aesthetic Appeal: A new exhaust can enhance the look of your vehicle with polished tips and unique designs.

Choosing the Right Exhaust System

When selecting an aftermarket exhaust system, consider the following factors to ensure you make the best choice for your 370Z:

  • Material: Stainless steel is durable and resistant to rust, while mild steel is less expensive but can corrode.
  • Type: Cat-back systems replace everything from the catalytic converter back, while axle-back systems only replace the muffler and exhaust tips.
  • Sound Level: Choose a system that fits your preference for loudness and tone.
  • Brand Reputation: Research brands and read reviews to ensure quality and performance.

Tools and Materials Needed for Installation

Before starting the installation process, gather the necessary tools and materials:

  • Jack and jack stands
  • Socket set
  • Wrenches
  • Rubber mallet
  • Exhaust hanger removal tool
  • New exhaust system
  • Gasket and clamps (if not included)

Step-by-Step Installation Guide

Step 1: Prepare Your Vehicle

Start by parking your Nissan 370Z on a flat surface and engaging the parking brake. Use the jack to lift the car and secure it with jack stands for safety.

Step 2: Remove the Stock Exhaust System

Begin by locating the exhaust hangers and using the exhaust hanger removal tool to detach them. Then, unscrew the bolts connecting the exhaust system to the catalytic converter and muffler. Carefully remove the stock exhaust components from the vehicle.

Step 3: Install the New Exhaust System

Position the new exhaust system starting from the catalytic converter. Ensure that all parts fit correctly and align with the hangers. Use the provided gaskets and clamps to secure the connections. Tighten all bolts to the manufacturer’s specifications.

Step 4: Check for Leaks and Final Adjustments

After installation, start the engine and listen for any unusual sounds that may indicate a leak. Check all connections and ensure everything is secure. Make any necessary adjustments to the exhaust hangers for optimal fit.

Performance Gains and Dyno Testing

After upgrading your exhaust system, it’s essential to measure the performance gains. A dyno test can provide precise data on horsepower and torque improvements. Many users report an increase from 330 to 350 HP after a successful exhaust upgrade, depending on other modifications and tuning.

Is It Worth the Upgrade?

Deciding whether to upgrade your Nissan 370Z exhaust system ultimately depends on your goals as a driver. Here are some factors to consider:

  • Budget: Consider the cost of the exhaust system and installation versus the performance gains.
  • Driving Style: If you enjoy spirited driving or track days, the upgrade may be worthwhile.
