One of the most effective ways to enhance its performance is by upgrading to an Invidia Cat-back exhaust system. This guide will walk you through the steps to achieve over 50 horsepower gains with this modification.
Understanding the Benefits of an Invidia Cat-back Exhaust
Before diving into the installation process, it is essential to understand the advantages of an Invidia Cat-back exhaust system:
- Increased Horsepower: The primary benefit is the significant increase in horsepower, often exceeding 50 HP.
- Improved Sound: Enjoy a deeper and more aggressive exhaust note that enhances the driving experience.
- Weight Reduction: Invidia systems are typically lighter than stock exhausts, which can improve performance.
- Enhanced Aesthetics: The polished finish and design add a sporty look to your Lexus IS-F.
Tools and Materials Needed
To successfully install the Invidia Cat-back exhaust, gather the following tools and materials:
- Socket set
- Wrench set
- Jack and jack stands
- Exhaust hanger removal tool
- New Invidia Cat-back exhaust system
- Safety glasses
- Gloves
Installation Steps
Step 1: Prepare Your Vehicle
Start by parking your Lexus IS-F on a level surface. Engage the parking brake and lift the rear of the vehicle using a jack. Secure it with jack stands to ensure safety during the installation process.
Step 2: Remove the Stock Exhaust
Using the socket set, loosen and remove the bolts securing the stock exhaust to the exhaust manifold. Carefully detach the exhaust hangers using the exhaust hanger removal tool. Once all components are free, remove the stock exhaust system from the vehicle.
Step 3: Install the Invidia Cat-back Exhaust
Begin by positioning the Invidia Cat-back exhaust in place. Align it with the exhaust manifold and attach it using the provided bolts. Ensure that the exhaust hangers are properly seated in their mounts. Tighten all bolts securely, but be cautious not to overtighten.
Step 4: Check for Leaks
Once the installation is complete, start the engine and listen for any unusual sounds. Check for exhaust leaks by feeling for air escaping around the joints. If everything sounds good, proceed to lower the vehicle.
Performance Tuning and Additional Modifications
To maximize the horsepower gains from your new exhaust, consider additional modifications:
- ECU Tune: A performance ECU tune can optimize fuel maps and timing for better performance.
- Cold Air Intake: Upgrading to a cold air intake can improve airflow to the engine, further increasing horsepower.
- High-Performance Headers: Installing aftermarket headers can enhance exhaust flow and complement the cat-back system.
Conclusion
Upgrading your Lexus IS-F with an Invidia Cat-back exhaust system is a straightforward process that can yield impressive results. By following the installation steps and considering additional modifications, you can achieve over 50 horsepower gains, transforming your driving experience. Enjoy the enhanced sound and performance of your upgraded Lexus IS-F!
