The WRX Turbo Back Exhaust system is a popular modification among Subaru enthusiasts, but like any aftermarket part, it can come with its own set of issues. In this article, we will explore common problems associated with WRX Turbo Back Exhaust systems, including leaks, drone, and fitment issues. Understanding these problems and their solutions can help you maintain optimal performance and sound from your exhaust system.
Common Issues with WRX Turbo Back Exhausts
- Exhaust Leaks
- Drone Noise
- Poor Fitment
Exhaust Leaks
Exhaust leaks can significantly affect the performance and sound of your WRX. They can occur at various points in the exhaust system, including joints, welds, and gaskets. Identifying and fixing these leaks is crucial to ensure your vehicle runs efficiently.
Identifying Exhaust Leaks
To identify leaks, you can perform a few simple checks:
- Visual Inspection: Look for signs of soot or discoloration around joints and welds.
- Sound Test: Listen for hissing or popping sounds while the engine is running.
- Smoke Test: Use a smoke machine to detect leaks by introducing smoke into the exhaust system.
Fixing Exhaust Leaks
Once you have identified a leak, the following solutions can be applied:
- Tighten Connections: Ensure all bolts and clamps are securely fastened.
- Replace Gaskets: Worn or damaged gaskets should be replaced to create a proper seal.
- Weld Repairs: For leaks in welded areas, consider re-welding or using exhaust sealant.
Drone Noise
Drone is an unwanted sound that can occur at specific RPM ranges, often described as a low-frequency rumble. This issue can be particularly bothersome during highway driving.
Causes of Drone Noise
Several factors can contribute to drone noise in WRX Turbo Back Exhaust systems:
- Exhaust Design: Some exhaust designs inherently produce more drone due to their configuration.
- Resonator Removal: Removing the resonator can amplify drone sounds.
- Material and Construction: The type of material and construction quality can affect sound resonance.
Solutions for Drone Noise
To reduce or eliminate drone noise, consider the following options:
- Install a Resonator: Adding a resonator can help dampen unwanted frequencies.
- Choose a Different Exhaust System: Some exhaust systems are designed to minimize drone.
- Adjust Exhaust Position: Sometimes adjusting the angle or position can reduce drone.
Poor Fitment
Poor fitment can lead to a variety of issues, including rattling, exhaust leaks, and increased drone. Ensuring that your Turbo Back Exhaust is properly fitted is essential for optimal performance.
Signs of Poor Fitment
Look out for the following signs that may indicate poor fitment:
- Rattling Noises: Unwanted sounds during acceleration or deceleration.
- Exhaust Contact: Parts of the exhaust hitting the chassis or suspension components.
- Misalignment: Visible gaps or uneven spacing between exhaust components.
Correcting Fitment Issues
To correct fitment issues, you can take the following steps:
- Adjust Mounting Points: Ensure that all hangers and mounts are correctly positioned.
- Use Spacers: If necessary, use spacers to achieve the proper alignment.
- Consult a Professional: If issues persist, consider having a professional install the exhaust.
Conclusion
Maintaining your WRX Turbo Back Exhaust system is essential for ensuring optimal performance and sound. By troubleshooting common issues like leaks, drone, and fitment problems, you can enhance your driving experience and prolong the life of your exhaust system. Regular inspections and timely fixes will help you enjoy the benefits of your modification without the headaches of common exhaust issues.
