The Basics of Exhaust Headers

What are Exhaust Headers?

Exhaust headers are a set of pipes that help exhaust gasses exit the engine more efficiently. Think of them as the track team's relay runners for your car's engine, passing the baton (in this case, exhaust gasses) quickly to improve your vehicle's performance.

How Do They Improve Performance?

Headers help optimize the flow of exhaust gasses, reducing back pressure and making it easier for the engine to "exhale." This results in a more efficient engine that can generate more power and run more smoothly. It's like clearing a stuffy nose; you can breathe easier and perform better.

Stock vs Aftermarket Headers

Your Nissan 370Z comes with stock headers, which are good but not great. Aftermarket headers are designed to provide optimized performance, often resulting in noticeable horsepower, torque, and better fuel efficiency. If you're serious about maximizing your 370Z's potential, aftermarket headers are worth considering.

Benefits of Upgrading Your 370Z's Exhaust Headers

Increased Horsepower

Let's be real, we all love more power. Upgrading your exhaust headers can give your 370Z that extra oomph, making your ride not just faster but also more responsive. Whether it's beating someone at a red light or just enjoying a spirited drive, that added horsepower makes all the difference.

Better Fuel Efficiency

It's not all about power; it's also about how far that power can take you. Improved exhaust flow can make your engine run more efficiently, translating to better fuel economy. So, while you're enjoying that extra horsepower, you're also visiting the gas station less frequently.

Enhanced Sound

If you're looking for that iconic sports car roar, look no further. Upgraded headers can transform your 370Z's exhaust note from a purr to a roar. It's not just noise; it's music to the ears of any car enthusiast.

Types of Headers for the Nissan 370Z

Shorty Headers

Shorty headers are compact and fit closely to the engine, making them ideal for tight spaces. They offer a boost in horsepower and torque, especially at low RPMs. If you're mostly driving around the city, these could be your go-to choice.

Long Tube Headers

Long tube headers offer the most significant performance gains but are more challenging to install due to their length. They excel in providing power at higher RPMs, making them perfect for racing or spirited driving on open roads. If you're looking to maximize performance, long tube headers are the way to go.

Step-by-Step Guide

Installing exhaust headers can be a detailed process. Start by disconnecting the battery and then removing the existing exhaust manifold.
