Lexus Is Power Gains: How a $600 Upgraded Downpipe from Agency Power Adds 20 Hp

The Lexus IS series has always been known for its blend of luxury and performance. However, for enthusiasts looking to enhance the driving experience, performance upgrades are essential. One of the most impactful modifications is the installation of an upgraded downpipe. In this article, we will explore how a $600 upgraded downpipe from Agency Power can add an impressive 20 horsepower to your Lexus IS.

Understanding the Role of the Downpipe

The downpipe is a crucial component of a vehicle’s exhaust system. It connects the turbocharger or exhaust manifold to the rest of the exhaust system. A factory downpipe is often restrictive, limiting the flow of exhaust gases and, consequently, the engine’s performance. Upgrading to a high-performance downpipe can significantly improve exhaust flow, resulting in increased horsepower and torque.

Benefits of Upgrading to an Agency Power Downpipe

  • Increased Horsepower: The primary benefit is the additional horsepower. The Agency Power downpipe is designed to reduce back pressure, allowing for better engine breathing and a gain of around 20 hp.
  • Improved Torque: Along with horsepower, you can expect an increase in torque, making your Lexus IS feel more powerful and responsive.
  • Enhanced Exhaust Sound: The upgraded downpipe provides a more aggressive exhaust note, enhancing the overall driving experience.
  • Better Turbo Response: For turbocharged models, an upgraded downpipe can lead to quicker spool times, improving throttle response.
  • Quality Construction: Agency Power downpipes are made from high-quality materials, ensuring durability and longevity.

Installation Process

Installing the Agency Power downpipe is a straightforward process, but it requires some mechanical knowledge. Here’s a brief overview of the installation steps:

  • Gather Tools: You will need basic hand tools, including wrenches, sockets, and possibly a lift or jack stands.
  • Remove the Factory Downpipe: Start by disconnecting the exhaust from the turbocharger or manifold, followed by removing any brackets or sensors attached to the factory downpipe.
  • Install the Agency Power Downpipe: Position the new downpipe in place and secure it with the provided hardware. Make sure to reconnect any sensors and exhaust components.
  • Check for Leaks: After installation, start the vehicle and check for exhaust leaks around the connections.

Performance Testing

After installation, it’s essential to test the performance gains. Many owners report noticeable improvements in both horsepower and torque, especially in the mid-range and upper RPMs. Using a dynamometer (dyno) is the best way to quantify these gains accurately.

Real-World Results

Several Lexus IS owners have shared their experiences after upgrading to the Agency Power downpipe. Many have reported:

  • 20 HP Gain: Most dyno tests have shown a consistent gain of around 20 hp.
  • Improved Throttle Response: Drivers have noted that their vehicles feel more responsive, especially during acceleration.
  • Enhanced Driving Experience: The overall driving experience has improved with a more aggressive exhaust note and better performance.

Conclusion

Upgrading to a $600 Agency Power downpipe is a worthwhile investment for any Lexus IS owner looking to enhance performance. With the potential for a 20 hp increase, improved throttle response, and a more engaging driving experience, this modification stands out as one of the best ways to unlock the full potential of your vehicle. Whether you are a casual driver or a performance enthusiast, the benefits are clear.
