Installing a competition turbo downpipe can significantly enhance your Mitsubishi Lancer Evolution’s performance. This guide provides essential best practices for EVO enthusiasts looking to install an APEXi downpipe effectively and safely.

Understanding the Importance of a Downpipe

A downpipe is a crucial component of your vehicle’s exhaust system. It connects the turbocharger to the rest of the exhaust system and plays a significant role in:

  • Improving exhaust flow
  • Enhancing turbo response
  • Increasing overall horsepower
  • Reducing turbo lag

Preparation Before Installation

Before you begin the installation process, ensure you have all the necessary tools and materials. Proper preparation can save you time and effort.

  • Tools Required:
    • Socket set
    • Wrenches
    • Torque wrench
    • Jack and jack stands
    • Safety glasses
    • Gloves
  • Materials Needed:
    • APEXi downpipe
    • Gaskets
    • Bolts and nuts
    • Exhaust sealant (optional)

Step-by-Step Installation Process

Follow these steps for a successful installation of your APEXi competition turbo downpipe:

  • Step 1: Safety First – Ensure your vehicle is parked on a flat surface. Engage the parking brake and wear safety glasses and gloves.
  • Step 2: Lift the Vehicle – Use a jack to lift the car and secure it with jack stands for safety.
  • Step 3: Remove the Old Downpipe – Locate the existing downpipe and remove any bolts or clamps securing it. Carefully detach it from the turbo and the rest of the exhaust system.
  • Step 4: Prepare the New Downpipe – Inspect the APEXi downpipe for any defects. Ensure that all necessary gaskets are available.
  • Step 5: Install the New Downpipe – Position the new downpipe in place. Align it with the turbo and the exhaust system. Secure it using the provided bolts and nuts.
  • Step 6: Torque Specifications – Use a torque wrench to tighten the bolts to the manufacturer’s specifications. This ensures a proper seal and prevents leaks.
  • Step 7: Recheck Connections – Double-check all connections and ensure everything is secure.
  • Step 8: Lower the Vehicle – Carefully remove the jack stands and lower the vehicle back to the ground.
  • Step 9: Test Drive – Start the engine and let it idle for a few minutes. Check for any leaks before taking your vehicle for a test drive.

Common Issues to Watch Out For

Even with careful installation, some issues may arise. Here are common problems to be aware of:

  • Exhaust Leaks: Ensure that all connections are tight and gaskets are properly placed.
  • Check Engine Light: If the light comes on after installation, check for loose connections or faulty sensors.
  • Excessive Noise: While a downpipe can increase sound, excessive noise may indicate a problem.
