The Subaru WRX is known for its impressive performance and rally heritage. One of the upgrades that enthusiasts often consider is the installation of aftermarket headers. In this article, we will explore the gains achieved with Grimmspeed WRX headers, focusing on how they enhance intake sound and throttle response.
Understanding WRX Headers
Headers are an essential component of the exhaust system. They are responsible for directing exhaust gases away from the engine and can significantly affect performance. The stock headers on the WRX can be restrictive, limiting the engine’s potential. Upgrading to Grimmspeed headers can lead to noticeable improvements.
Benefits of Grimmspeed WRX Headers
- Improved Exhaust Flow: Grimmspeed headers are designed to reduce back pressure, allowing for better exhaust flow.
- Enhanced Throttle Response: With increased flow, the engine can respond more quickly to throttle inputs.
- Better Sound: Upgrading to Grimmspeed headers enhances the engine’s sound, providing a more aggressive tone.
- Increased Horsepower: The improved flow characteristics can lead to a measurable increase in horsepower.
How Grimmspeed Headers Enhance Intake Sound
The sound of a vehicle can significantly enhance the driving experience. Grimmspeed headers are designed to produce a deeper, more aggressive exhaust note. This change in sound is due to the improved flow and reduced restrictions compared to stock headers.
Many WRX owners report that the installation of Grimmspeed headers gives their vehicle a more pronounced growl, especially during acceleration. The enhanced intake sound makes driving more enjoyable and provides a sense of connection to the performance of the vehicle.
Throttle Response Improvements
Throttle response is crucial for any performance-oriented vehicle. Grimmspeed headers contribute to quicker throttle response by reducing back pressure and allowing exhaust gases to exit the engine more efficiently. This efficiency translates to a more immediate response when the driver presses the accelerator.
With improved throttle response, drivers can expect a more engaging driving experience. This is particularly noticeable during spirited driving or when navigating twisty roads, where quick acceleration can make a significant difference.
Installation Considerations
When considering the installation of Grimmspeed headers, there are a few factors to keep in mind:
- Professional Installation: While some experienced DIYers may tackle the installation, it is often recommended to have a professional perform the work to ensure proper fitment and avoid potential issues.
- Supporting Mods: To maximize the benefits of headers, consider pairing them with other performance modifications, such as a high-flow cat-back exhaust or an upgraded tune.
- Legal Considerations: Be aware of local emissions laws, as some header installations may not comply with regulations.
Conclusion
Upgrading to Grimmspeed WRX headers can provide significant gains in both intake sound and throttle response. The combination of improved exhaust flow and a more aggressive sound creates a more enjoyable driving experience. For WRX enthusiasts looking to enhance their vehicle’s performance, Grimmspeed headers are a worthy investment.
