by Alex Braham 48 views

Hey guys! Thinking about giving your 2007 Lexus IS350 a little extra oomph? One of the best ways to do that is by upgrading your exhaust system, and the F Sport exhaust is a popular choice. Let's dive into everything you need to know about this awesome upgrade.

Why Upgrade to an F Sport Exhaust?

So, why should you even consider swapping out your stock exhaust for an F Sport one? Well, there are several compelling reasons.

First off, sound. The F Sport exhaust gives your IS350 a much throatier and more aggressive sound. It’s not obnoxiously loud, but it definitely lets people know you mean business. The deep rumble at idle and the satisfying growl when you accelerate can really transform your driving experience.

Next up, there’s the potential for a slight performance boost. While it’s not going to turn your IS350 into a race car overnight, an F Sport exhaust is designed to improve exhaust flow. This can lead to a few extra horsepower and a little more torque, especially in the mid-range. You might not feel a huge difference, but every little bit helps, right?

And let's not forget about the aesthetics. The F Sport exhaust typically comes with polished tips that look fantastic. They add a touch of sporty elegance to the rear of your car, making it stand out from the crowd. Plus, knowing you have a quality aftermarket part under your ride just feels good.

Finally, there’s the quality and reliability. F Sport parts are designed by Lexus, so you know they’re built to last. They’re made from high-quality materials and are engineered to fit your IS350 perfectly. You won’t have to worry about rust, leaks, or other common issues that can plague cheaper aftermarket exhausts.

Choosing the Right F Sport Exhaust

Alright, so you’re sold on the idea of an F Sport exhaust. Now, how do you choose the right one for your 2007 Lexus IS350? Here’s what you need to keep in mind:

Compatibility

This might seem obvious, but make sure the exhaust is actually compatible with your 2007 IS350. While many parts are interchangeable between model years, it’s always best to double-check. Look for exhausts specifically listed as compatible with the 2006-2013 IS350 models to be safe.

New or Used?

You have the option of buying a new or used F Sport exhaust. A new exhaust will obviously be in pristine condition and come with all the necessary hardware. However, it will also be more expensive. A used exhaust can save you some money, but make sure to inspect it carefully for any signs of damage or wear. Check for rust, dents, and any evidence of repairs.

Exhaust Type

Cat-back systems replace everything from the catalytic converters back, while axle-back systems only replace the mufflers and tips. Cat-back systems generally offer better performance gains and a more aggressive sound, but they’re also more expensive and can be more complicated to install. Axle-back systems are a more budget-friendly option that still provides a noticeable improvement in sound and appearance.

Material

F Sport exhausts are typically made from stainless steel, which is durable and resistant to corrosion. However, some cheaper exhausts might be made from aluminized steel, which is more prone to rust. Stainless steel is the way to go for longevity and peace of mind.

Reviews and Reputation

Before you pull the trigger, read reviews and check the reputation of the seller or manufacturer. See what other IS350 owners have to say about the exhaust you’re considering. Are they happy with the sound? Was the installation easy? Did they experience any problems? Real-world feedback can be invaluable.

Installation: DIY or Professional?

Okay, you’ve got your F Sport exhaust. Now it’s time to install it. You basically have two options: do it yourself or hire a professional.

DIY Installation

If you’re mechanically inclined and have some experience working on cars, you might be able to install the exhaust yourself. It’s not a super complicated job, but it does require some basic tools and know-how. You’ll need a jack, jack stands, wrenches, sockets, and possibly a saw or cutting tool to remove the old exhaust.

The main advantage of DIY installation is that it saves you money. You won’t have to pay a shop for labor. However, it can also be time-consuming, and there’s always the risk of messing something up. Make sure to watch some tutorial videos and read the instructions carefully before you start.

Professional Installation

If you’re not comfortable working on cars or don’t have the necessary tools, it’s best to have a professional install the exhaust. This will cost you more money, but you’ll have the peace of mind knowing that the job is done correctly.

A professional installer will have the right tools and experience to get the job done quickly and efficiently. They can also identify and fix any potential problems that might arise during the installation. Plus, if anything goes wrong, you’ll have someone to hold accountable.

Step-by-Step Overview

Whether you're tackling the install yourself or having a pro do it, here's a general idea of what the process looks like:

  1. Preparation: Gather your tools, put on safety glasses and gloves, and make sure your car is properly supported on jack stands.
  2. Remove the Old Exhaust: Loosen the bolts connecting the old exhaust to the catalytic converters. You might need to use some penetrating oil to loosen rusty bolts. Carefully remove the old exhaust system, working from the back to the front.
  3. Install the New Exhaust: Install the new F Sport exhaust in the reverse order of removal. Make sure all the connections are tight and properly aligned. Use new gaskets and hardware if necessary.
  4. Final Check: Double-check all the connections and make sure the exhaust is not hitting any part of the car. Start the engine and listen for any leaks or unusual noises.

Potential Issues and How to Avoid Them

Even with the best planning, things can sometimes go wrong during an exhaust installation. Here are some potential issues and how to avoid them:

  • Rusty Bolts: Old exhaust systems often have rusty bolts that are difficult to remove. Use penetrating oil and let it soak for a while before attempting to loosen the bolts. If the bolts are too corroded, you might need to use a torch or cut them off.
  • Leaks: Exhaust leaks can cause a loss of power and can be dangerous. Make sure all the connections are tight and use new gaskets if necessary. After the installation, check for leaks by listening for hissing sounds or feeling for exhaust fumes.
  • Fitment Issues: Sometimes, aftermarket exhausts don’t fit perfectly. This can be due to manufacturing tolerances or slight variations in the car’s chassis. If you encounter fitment issues, try adjusting the hangers or using shims to align the exhaust properly. If the problem is severe, you might need to return the exhaust and try a different one.
  • Noise: While most people upgrade their exhaust for a better sound, sometimes the new exhaust can be too loud or have an annoying drone. Research the exhaust you’re considering and read reviews to get an idea of the sound characteristics. You can also add resonators or mufflers to the exhaust system to reduce the noise level.

Maintaining Your F Sport Exhaust

Once you’ve installed your F Sport exhaust, it’s important to maintain it properly to keep it looking and sounding its best. Here are some tips:

  • Regular Cleaning: Clean the exhaust tips regularly with a stainless steel cleaner to remove dirt, grime, and water spots. This will keep them looking shiny and new.
  • Check for Leaks: Periodically inspect the exhaust system for leaks. Look for signs of exhaust fumes or listen for hissing sounds. Repair any leaks promptly to prevent further damage.
  • Inspect for Damage: Check the exhaust system for dents, cracks, or rust. Repair any damage as soon as possible to prevent it from getting worse.
  • Avoid Harsh Chemicals: Don’t use harsh chemicals or abrasive cleaners on the exhaust system. These can damage the finish and cause corrosion.

Conclusion

Upgrading to an F Sport exhaust is a great way to enhance the sound, appearance, and performance of your 2007 Lexus IS350. By choosing the right exhaust, installing it properly, and maintaining it regularly, you can enjoy years of driving pleasure. Whether you decide to do it yourself or hire a professional, the key is to do your research and take your time. With a little effort, you can transform your IS350 into a true head-turner. Now go out there and make your ride sound as good as it looks!
