The HKS Subaru WRX Turbo Back Exhaust system is a popular choice among car enthusiasts looking to enhance performance and sound. However, installation can present several challenges. Understanding these common issues can help streamline the process and ensure a successful installation.
Common Installation Challenges
- Misalignment of exhaust components
- Difficulty in removing the stock exhaust
- Clearance issues with underbody components
- Inadequate tools for installation
- Exhaust leaks due to improper sealing
Misalignment of Exhaust Components
One of the most common issues during installation is the misalignment of exhaust components. This can lead to vibrations and rattling noises, affecting overall performance.
How to Fix Misalignment
To fix misalignment, follow these steps:
- Start by loosely fitting all components together.
- Ensure that the hangers are aligned properly before tightening.
- Adjust the positioning of each piece to achieve a straight exhaust line.
- Tighten all bolts and clamps gradually, checking alignment as you go.
Difficulty in Removing the Stock Exhaust
Removing the stock exhaust can be challenging, especially if it has been on the vehicle for a long time. Rust and corrosion may cause bolts to seize, complicating the removal process.
How to Remove the Stock Exhaust
Here are some tips to facilitate the removal of the stock exhaust:
- Use penetrating oil on the bolts and let it sit for at least 15 minutes.
- Utilize a breaker bar for added leverage when loosening bolts.
- Consider using a saw or cutting tool if bolts are completely seized.
- Have a friend assist you in holding the exhaust while you remove it.
Clearance Issues with Underbody Components
Another challenge is ensuring proper clearance between the new exhaust system and underbody components. Insufficient clearance can lead to contact and damage over time.
How to Ensure Proper Clearance
To avoid clearance issues, consider the following:
- Check the exhaust routing against the underbody before final installation.
- Adjust hangers to provide adequate space between the exhaust and components.
- Test fit the exhaust system before securing it completely.
- Inspect for any contact points once installed and make adjustments as necessary.
Inadequate Tools for Installation
Using the wrong tools can significantly hinder the installation process. Inadequate or improper tools may lead to stripped bolts or damage to exhaust components.
Essential Tools for Installation
Ensure you have the following tools on hand for a smooth installation:
- Socket set with various sizes
- Torque wrench for proper tightening
- Penetrating oil for rusted bolts
- Rubber mallet for gentle adjustments
- Jack stands for vehicle support
Exhaust Leaks Due to Improper Sealing
Exhaust leaks can occur if the connection points are not sealed correctly. This can result in performance issues and unwanted noise.
How to Prevent Exhaust Leaks
To prevent leaks, follow these sealing tips:
- Use high-temperature exhaust sealant on all connection points.
- Ensure gaskets are in good condition and replace if necessary.
- Tighten all clamps securely but avoid over-tightening.
- Inspect for leaks after installation using a smoke test or by listening for hissing sounds.
Conclusion
Installing an HKS Subaru WRX Turbo Back Exhaust can enhance your vehicle’s performance and sound. By being aware of common installation challenges and implementing the suggested solutions, you can ensure a successful installation process. Proper preparation and the right tools will lead to a satisfying upgrade for your WRX.
