It offers a noticeable improvement in exhaust flow, which can translate to a slight increase in horsepower and, more importantly, a more aggressive and sporty sound. If you're looking to add some character to your IS350, this is a great place to start. But before you dive in headfirst, let's talk about what's involved in installing an Invidia midpipe on your 2007 Lexus IS350. This article will guide you through the process, covering everything from the tools you'll need to the potential benefits you can expect. We'll also touch on some important considerations to keep in mind, like potential fitment issues and the overall impact on your car's sound.

Why Choose an Invidia Midpipe?

When it comes to aftermarket exhaust components, Invidia is a well-respected brand known for its quality and performance. Their midpipes are designed to optimize exhaust flow, which can lead to several benefits for your IS350. First and foremost, you'll likely notice a change in the exhaust note. The Invidia midpipe typically eliminates the secondary catalytic converters, resulting in a deeper, more resonant sound. This is a significant improvement for those who find the stock exhaust a bit too quiet. In addition to the improved sound, an Invidia midpipe can also offer a slight performance boost. By reducing backpressure in the exhaust system, the engine can breathe more freely, potentially leading to a few extra horsepower and improved throttle response. While the gains might not be massive, they can certainly be felt, especially in conjunction with other modifications like an aftermarket intake. Furthermore, Invidia midpipes are generally constructed from high-quality materials like stainless steel, ensuring durability and resistance to corrosion. This is crucial for a component that's exposed to the elements and the harsh conditions under the car. The installation process is also relatively straightforward, making it a popular choice for DIY enthusiasts. However, it's essential to ensure proper fitment and sealing to avoid any exhaust leaks. So, if you're looking for a combination of improved sound, potential performance gains, and long-lasting durability, the Invidia midpipe is definitely worth considering for your 2007 Lexus IS350.

Tools and Materials You'll Need

Before you even think about wrenching on your IS350, you need to gather all the necessary tools and materials. Having everything on hand will make the installation process much smoother and prevent frustrating trips to the auto parts store mid-project. Here's a comprehensive list of what you'll need:

  • Invidia Midpipe: Obviously, this is the star of the show. Make sure you order the correct midpipe specifically designed for the 2007 Lexus IS350.
  • Socket Set: A good quality socket set with various sizes is essential. You'll likely need sockets ranging from 10mm to 17mm.
  • Wrench Set: Similar to the socket set, a wrench set with a range of sizes is also necessary. Combination wrenches are a good option.
  • Ratchet: You'll need a ratchet to turn the sockets and wrenches. A 3/8-inch drive ratchet is a good all-around choice.
  • Extensions: Socket extensions of various lengths will help you reach those hard-to-get bolts.
  • Penetrating Oil: This is your best friend when dealing with rusty or stubborn bolts. Apply it liberally to any bolts you'll be removing.
  • Jack and Jack Stands: You'll need to safely lift the car to access the exhaust system. Never work under a car supported only by a jack!
  • Wheel Chocks: Place wheel chocks behind the rear wheels to prevent the car from rolling.
  • Gloves: Protect your hands from dirt, grease, and sharp edges.
  • Safety Glasses: Always wear safety glasses when working under a car to protect your eyes from debris.
  • Torque Wrench: This is crucial for tightening the bolts to the correct torque specifications.
  • Exhaust Hangers Removal Tool (Optional): This tool can make removing the exhaust hangers much easier, but it's not strictly necessary.
  • New Exhaust Gaskets: It's always a good idea to replace the exhaust gaskets when installing a new midpipe to ensure a proper seal.
  • Anti-Seize Compound: Apply this to the threads of the bolts to prevent them from seizing in the future.
  • O2 Sensor Socket (Optional): If you need to remove the O2 sensors, this socket will make the job easier.

Step-by-Step Installation Guide

Okay, guys, with all the tools and materials ready, let's get down to the nitty-gritty of installing the Invidia midpipe on your 2007 Lexus IS350. Remember to work in a well-ventilated area and take your time. Rushing the job can lead to mistakes and potential damage. Here's a step-by-step guide:

  1. Prepare the Car: Start by parking your IS350 on a level surface. Engage the parking brake and chock the rear wheels. Loosen the lug nuts on the front wheels. Use a jack to lift the front of the car and securely support it with jack stands. Never work under a car supported only by a jack!
  2. Disconnect the Battery: Disconnecting the negative terminal of the battery is a good safety precaution to prevent any electrical issues during the installation.
  3. Locate the Stock Midpipe: The midpipe is located underneath the car, connecting the exhaust manifolds to the rear section of the exhaust system.
  4. Remove the O2 Sensors (If Necessary): Some midpipes require you to remove the O2 sensors from the stock midpipe and install them on the new one. If this is the case, use an O2 sensor socket to carefully remove the sensors. Be careful not to damage them.
  5. Loosen the Bolts: Use penetrating oil on all the bolts connecting the stock midpipe to the exhaust manifolds and the rear section of the exhaust system. Let it soak for a few minutes before attempting to loosen the bolts.
  6. Remove the Stock Midpipe: Carefully remove the bolts and nuts securing the stock midpipe. You may need to use a wrench and a socket in combination to get them loose. Support the midpipe as you remove the last bolt to prevent it from falling.
  7. Install the Invidia Midpipe: Align the Invidia midpipe with the exhaust manifolds and the rear section of the exhaust system. Use new exhaust gaskets to ensure a proper seal. Install the bolts and nuts, but don't tighten them completely yet.
  8. Install the O2 Sensors (If Applicable): If you removed the O2 sensors earlier, install them into the new midpipe. Tighten them to the correct torque specification.
  9. Tighten the Bolts: Once everything is aligned, tighten all the bolts and nuts to the correct torque specifications using a torque wrench. This is crucial to prevent exhaust leaks.
  10. Reinstall the Battery: Reconnect the negative terminal of the battery.
  11. Lower the Car: Carefully lower the car back to the ground.
  12. Start the Engine: Start the engine and listen for any exhaust leaks. If you hear any leaks, tighten the bolts further.
  13. Test Drive: Take the car for a test drive to ensure everything is working properly and that you're happy with the sound.

Important Considerations and Potential Issues

While the installation of an Invidia midpipe is generally straightforward, there are a few important considerations to keep in mind. First and foremost, fitment can sometimes be an issue. Aftermarket parts aren't always a perfect match for the factory components, so you might encounter some slight discrepancies. Be prepared to make minor adjustments if necessary. Another important factor is the sound. While most people love the more aggressive exhaust note, it's important to be aware that it can be quite loud, especially at higher RPMs. If you're concerned about noise levels, you might want to consider a resonated midpipe, which helps to dampen the sound. Additionally, deleting the secondary catalytic converters can sometimes trigger a check engine light. This is because the O2 sensors detect the change in exhaust composition. To avoid this, you might need to install O2 sensor spacers or have the ECU tuned. Finally, remember that modifying your car's exhaust system can potentially affect your warranty. It's always a good idea to check with your dealer or warranty provider to see if the modification will void any coverage.
