The N55 engine is known for its impressive performance and tuning potential. One popular modification among enthusiasts is the installation of a downpipe, specifically the VRSF downpipe. This article will guide you through the installation process, highlight the performance benefits, and provide a cost breakdown for this upgrade.
Benefits of Installing the VRSF Downpipe
The VRSF downpipe is designed to replace the factory unit, allowing for improved exhaust flow and reduced back pressure. Here are some key benefits:
- Increased Horsepower: The VRSF downpipe can significantly increase horsepower, providing a noticeable performance boost.
- Enhanced Sound: Installing a downpipe changes the exhaust note, giving your N55 a more aggressive sound.
- Better Turbo Response: With improved exhaust flow, turbo response is enhanced, leading to quicker throttle response.
- Weight Reduction: The VRSF downpipe is often lighter than the stock unit, contributing to overall weight savings.

Before starting the installation, ensure you have the following tools on hand:
- Socket set (including extensions)
- Torque wrench
- Flathead and Phillips screwdrivers
- O2 sensor socket
- Jack and jack stands
- Safety glasses and gloves
Step-by-Step Installation Guide
Step 1: Preparation
Start by parking your car on a level surface and engaging the parking brake. Allow the exhaust system to cool down completely before beginning the installation.
Step 2: Lift the Vehicle
Use a jack to lift the front of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
Step 3: Remove the Stock Downpipe
Locate the stock downpipe. Disconnect the O2 sensors and any clamps or bolts securing it to the exhaust system. Carefully remove the stock downpipe from the vehicle.
Step 4: Install the VRSF Downpipe
Position the VRSF downpipe in place. Reinstall the O2 sensors and secure the downpipe with the provided hardware. Ensure all connections are tight and properly aligned.
Step 5: Reconnect Exhaust Components
Reconnect any exhaust components that were removed during the installation. Double-check all connections and fittings for leaks.
Step 6: Lower the Vehicle
Carefully lower the vehicle back to the ground and remove the jack stands. Start the engine and listen for any unusual sounds.
Performance Gains
After installing the VRSF downpipe, many users report significant performance improvements. Here’s what you can expect:
- Up to 20-30 additional horsepower, depending on other modifications.
- Improved throttle response and acceleration.
- Enhanced turbo spool sound and exhaust note.
Cost Breakdown
The total cost of installing a VRSF downpipe can vary based on several factors, including labor costs if you choose to have it installed by a professional. Here’s a breakdown:
- VRSF Downpipe: $300 – $500
- Labor (if applicable): $100 – $200
- Miscellaneous Parts (gaskets, bolts): $20 – $50
In total, you can expect to spend between $420 and $750 for this upgrade, depending on your choices and local labor rates.
