The FA20 engine, found in various Subaru models, has gained popularity among car enthusiasts for its performance and tuning potential. One of the most effective modifications for enhancing the performance of the FA20 engine is the installation of a high-flow catalytic converter. This article explores the cost, benefits, and performance gains associated with high-flow catalytic converters for the FA20.
Understanding High-Flow Catalytic Converters
A high-flow catalytic converter is designed to improve exhaust flow, which can lead to increased horsepower and torque. Unlike stock catalytic converters, which are built to meet strict emissions regulations, high-flow options prioritize performance while still maintaining a level of emissions compliance. These converters are typically made with less restrictive materials and designs.
Cost of High-Flow Catalytic Converters
The cost of high-flow catalytic converters can vary significantly based on brand, material, and design. On average, you can expect to pay between $300 and $1,200 for a quality unit. Factors influencing the price include:
- Brand reputation and quality
- Material used (stainless steel vs. mild steel)
- Design complexity and features
- Compatibility with specific FA20 models
While the initial investment may seem high, many enthusiasts consider it a worthwhile expenditure due to the performance benefits gained.
Benefits of High-Flow Catalytic Converters
Installing a high-flow catalytic converter offers several advantages for FA20 engine owners:
- Improved Exhaust Flow: High-flow converters reduce backpressure, allowing for a more efficient exhaust system.
- Increased Horsepower: Enhanced exhaust flow can lead to noticeable power gains, especially when combined with other modifications.
- Better Sound: Many enthusiasts appreciate the deeper, more aggressive exhaust note that comes with high-flow converters.
- Weight Reduction: Some high-flow options are lighter than stock converters, contributing to overall vehicle performance.
These benefits make high-flow catalytic converters an attractive option for those looking to maximize their FA20 engine’s potential.
Performance Gains with High-Flow Catalytic Converters
When it comes to performance gains, high-flow catalytic converters can significantly impact your vehicle’s overall output. The extent of these gains depends on various factors:
- Supporting Modifications: The greatest gains are often seen when high-flow converters are paired with other performance upgrades, such as a cold air intake, turbocharger, or upgraded exhaust system.
- Tuning: Proper tuning of the engine management system is crucial to fully realize the benefits of a high-flow catalytic converter.
- Driving Conditions: Real-world performance may vary based on driving style and conditions, with higher gains typically seen in spirited driving scenarios.
On average, enthusiasts report power increases ranging from 5 to 20 horsepower after installing a high-flow catalytic converter, depending on the specific setup and tuning.
Considerations Before Upgrading
Before deciding to upgrade to a high-flow catalytic converter, consider the following:
- Emissions Compliance: Ensure that the high-flow converter meets your local emissions regulations to avoid legal issues.
- Warranty Implications: Check if the modification affects your vehicle’s warranty.
- Installation: Professional installation is recommended to ensure proper fitment and performance.
Being informed about these considerations can help you make a more educated decision regarding your vehicle’s modifications.
Conclusion
High-flow catalytic converters offer substantial benefits for FA20 engine enthusiasts looking to enhance performance. While the initial cost may vary, the potential gains in horsepower, torque, and overall driving experience make it a worthwhile investment for many. By understanding the costs, benefits, and performance implications, you can make an informed choice about upgrading your FA20 engine.
