As you can see, each of these headers offers unique features and benefits. That’s why it's important to choose a performance header that aligns with your performance goals. Whether your BRZ is a daily driver or a track weapon, there's a header out there that's perfect for your build.
An exhaust manifold serves as the initial segment of your BRZ's exhaust system, directly connected to the engine's cylinder head. Unlike a stock exhaust manifold, which can restrict airflow, an aftermarket header facilitates smoother, more efficient gas flow from the engine to the rest of your exhaust, increasing your vehicle's performance capabilities.
By streamlining the flow of exhaust gases from the engine's cylinders, a well-designed header can significantly improve your BRZ's horsepower and torque. The improved exhaust flow reduces back pressure, allowing the engine to breathe easier and generate more power. This translates to quicker acceleration, more responsive throttle control, and an overall enhanced driving experience.
In addition to performance gains, a header plays a pivotal role in terms of changing the exhaust note of your Subaru BRZ. The design and material of the aftermarket header influence the exhaust’s sound, adding a distinct sound to your exhaust system. Whether you're aiming for a deep, throaty growl or a subtle, refined sound, the right header can make a big difference.
Opting for a 4-1 header design means prioritizing peak horsepower. In this configuration, all four exhaust pipes merge into a single collector, promoting higher RPM performance. Ideal for track days and spirited driving, 4-1 headers unleash the full potential of your BRZ's high-revving engine.
The 4-1 header design produces a sharp, aggressive exhaust note, particularly at higher RPMs. This makes it a favorite among BRZ owners who want a race-inspired auditory experience to match their modified BRZ’s performance capabilities.
If you're looking for a balanced improvement across the RPM range, 4-2-1 headers are your go-to choice. These headers feature two pairs of pipes that merge into two collectors, which then combine into a single outlet. This design enhances low to mid-range torque, making it well-suited for daily driving conditions.
The 4-2-1 header configuration yields a more subdued but sporty exhaust tone. It offers a fuller sound profile, with a blend of boxer rumble and an aggressive exhaust note at high rpms, making it perfect for various driving scenarios.
Equal-length headers offer a consistent exhaust flow from each cylinder, optimizing performance and throttle response. On the other hand, unequal-length headers may sacrifice a bit of performance for a unique, boxer-engine sound that Subaru owners love.
Equal-length headers produce a smooth, consistent exhaust note, often described as "refined" or "sophisticated." Unequal-length headers, conversely, deliver that iconic Subaru "rumble," a sound that is both distinct and beloved within the automotive community.
Switching to an aftermarket header can significantly boost your BRZ's horsepower, often adding anywhere from 15 to 30 horsepower depending on the design and material. If you're looking to add more power to your BRZ, a header upgrade is a step in the right direction.
In addition to adding horsepower, aftermarket headers can significantly improve your Subaru BRZ's torque, typically adding between 10 to 20 lb-ft. Aftermarket headers are particularly effective at eliminating the notorious torque dip that many FA20-equipped BRZs experience around the 4k rpm mark. By resolving this issue, the headers not only increase your car's overall torque but also dramatically improve acceleration and responsiveness. The result is a BRZ that's not only faster but also more engaging and enjoyable to drive.
The cost of a BRZ header can vary widely, ranging from $300 for budget-friendly options to upwards of $1700 for high-end, hand-welded headers. Your choice will depend on your specific performance goals and budget constraints.
Expect to pay between $200 and $400 for professional installation. While some enthusiasts opt for a DIY approach, those unfamiliar with car mechanics may find the investment in professional installation to be well worth it.
Generally low, maintenance costs can include occasional cleaning and gasket replacement, usually not exceeding $50 annually.
You'll need a set of wrenches, a socket set, jack stands, and a torque wrench for the installation.
Before you begin, make sure to disconnect the battery and elevate the car safely on jack stands. The exhaust should be cold to the touch to ensure you don’t burn yourself during the removal process of the stock exhaust manifold.
Start by removing the old header, followed by installing the new gaskets and header. Tighten all bolts to the manufacturer's specifications, reconnect the O2 sensors, and finally, reconnect the battery and start the car to check for any leaks.
The most frequent issues you'll encounter with aftermarket Subaru BRZ header are exhaust leaks and rust. An exhaust leak can often be identified by a hissing sound or a noticeable drop in performance. Rust, on the other hand, is usually visible during a routine inspection. Both issues should be addressed promptly to prevent further complications. For leaks, replacing the gaskets or tightening the bolts can often solve the problem. For rust, it may be necessary to replace the header entirely, especially if the rust has compromised the structural integrity of the unit.
Regular inspections can help you catch these problems before they escalate. If you notice any of these issues, it's important to address them immediately before they get worse and cause other potential issues.
A cold air intake can further improve your BRZ's performance by allowing the engine to breathe more easily, often resulting in horsepower gains. This is an easy performance upgrade that usually doesn’t cost much and can be done in a few hours.
A catback exhaust system can complement your new header, offering additional horsepower gains and a more aggressive exhaust note. We highly recommend buying a catback exhaust with your aftermarket header if you don’t already have one to take full advantage of your upgrades.
An ECU tune can optimize your engine's performance parameters to take full advantage of your new header, cold air intake, and catback exhaust, making it the final piece in the performance puzzle for your BRZ. We also recommend getting your car tuned to prevent potential performance issues if you happen to be running a catless exhaust and want to prevent a check engine light.
