The Subaru WRX has gained a reputation for its performance and tuning potential among automotive enthusiasts. One of the key modifications that can enhance the performance of a Stage 2 WRX is the downpipe. In this article, we will compare two popular downpipe options: the AEM and MRT.
Understanding Downpipes
A downpipe is a crucial component of a vehicle’s exhaust system, connecting the turbocharger to the rest of the exhaust system. By replacing the factory downpipe with a high-performance unit, enthusiasts can improve exhaust flow, reduce turbo lag, and increase horsepower and torque.
Performance Benefits of Upgrading to a Stage 2 Downpipe
Upgrading to a Stage 2 downpipe offers several performance benefits, including:
- Increased horsepower and torque
- Improved throttle response
- Enhanced turbo spool time
- Better sound quality from the exhaust
AEM Downpipe Overview
The AEM downpipe is designed to maximize exhaust flow while maintaining durability and reliability. It is constructed from high-quality materials and features a mandrel-bent design to minimize restrictions.
Features of AEM Downpipe
- Stainless steel construction for corrosion resistance
- Designed for optimal exhaust flow
- Compatible with factory and aftermarket exhaust systems
- Easy installation with all necessary hardware included
Performance Metrics
The AEM downpipe is known for delivering significant performance gains. Users have reported an increase in horsepower ranging from 15 to 25 HP, depending on other modifications and tuning.
MRT Downpipe Overview
The MRT downpipe is another popular choice among WRX enthusiasts. It is engineered to provide a balance of performance and sound, making it an attractive option for those looking to enhance their vehicle’s capabilities.
Features of MRT Downpipe
- High-quality stainless steel construction
- Designed to reduce back pressure
- Includes a high-flow catalytic converter
- Straightforward installation process
Performance Metrics
The MRT downpipe also offers impressive performance improvements. Users typically experience gains of 10 to 20 HP, along with a noticeable difference in exhaust note quality.
Comparative Analysis: AEM vs MRT
When comparing the AEM and MRT downpipes, several factors come into play, including performance, sound, and ease of installation.
Performance Comparison
Both downpipes provide significant performance enhancements, but the AEM tends to offer slightly higher horsepower gains in most cases. The MRT, while still effective, focuses more on sound quality and reducing back pressure.
Sound Quality
Sound is a subjective aspect of downpipe performance. The AEM downpipe produces a more aggressive exhaust note, which many enthusiasts prefer. In contrast, the MRT downpipe offers a deeper, more refined sound that appeals to those looking for a balance between performance and daily drivability.
Installation Ease
Both downpipes are designed for straightforward installation. However, some users report that the AEM downpipe may require slightly more effort due to its design. The MRT downpipe often comes with clear instructions and all necessary hardware, making it a user-friendly choice.
Conclusion
In conclusion, both the AEM and MRT downpipes are excellent choices for enhancing the performance of a Stage 2 WRX. The AEM downpipe may be better suited for those seeking maximum horsepower gains, while the MRT downpipe is ideal for enthusiasts who prioritize sound quality and ease of installation. Ultimately, the choice between the two will depend on personal preferences and specific performance goals.
Additional Considerations
When choosing a downpipe, consider the following:
- Your specific performance goals
- Compatibility with other modifications
- Local emissions regulations
- Budget for the upgrade
