What is a Performance Exhaust?

A performance exhaust is an aftermarket exhaust system designed to improve your car’s performance, sound, and efficiency compared to the stock exhaust system that comes with your vehicle. For a car like the 2018 Hyundai Elantra SEL Performance Exhaust, upgrading to a performance exhaust can offer several advantages that enhance the driving experience.

Key Features of a Performance Exhaust

1. Increased horsepower and torque
   A performance exhaust optimizes the flow of exhaust gases from the engine, which reduces back pressure and allows the engine to “breathe” better. This leads to more efficient fuel combustion and increases both horsepower and torque, improving your car’s overall performance.
2. Improved exhaust sound
   One of the most noticeable differences with a performance exhaust is the sound. While stock exhausts are designed to minimize noise, performance exhausts are tuned to deliver a deeper, more aggressive exhaust note. This makes your 2018 Hyundai Elantra SEL sound more powerful and sporty on the road.

3. Better Fuel Efficiency
   With the improved airflow from a performance exhaust, your engine works more efficiently. In many cases, this can lead to better fuel economy, especially when driving at highway speeds. However, the extent of fuel savings may depend on driving habits and the specific exhaust system you choose.
4. Longer-Lasting Materials
   Performance exhaust systems are often made from more durable materials like stainless steel or aluminized steel, which are more resistant to corrosion than standard exhaust systems. This means they tend to last longer, especially in harsh weather conditions.

How to Install a Performance Exhaust on a 2018 Hyundai Elantra SEL

Installing a performance exhaust on your 2018 Hyundai Elantra SEL can be a rewarding way to enhance your car’s sound and performance. While it’s possible to have a professional do the job, you can also install it yourself with the right tools and guidance. This step-by-step guide will walk you through the process of installing a performance exhaust system on your Elantra SEL, helping you save money while enjoying the satisfaction of a DIY upgrade.

Tools You’ll Need:

• Socket wrench set
• Jack and jack stands or car ramps
• Penetrating oil (for rusted bolts)
• Exhaust hanger removal tool (optional but helpful)
• Torque wrench
• Gloves and safety goggles

Step 1: Prepare Your Vehicle

1. Park on a Level Surface
   Ensure your vehicle is parked on a flat, stable surface and put it in park (or first gear if it’s a manual). Activate the parking brake to ensure additional safety.
2. Lift the vehicle
   Utilize a jack to raise the back of the vehicle and support it with jack stands.. Alternatively, you can use car ramps. Make sure the car is lifted high enough for you to easily access the exhaust system underneath.
3. Allow the exhaust to cool.
   If you’ve recently driven the car, allow the exhaust system to cool down before starting the installation. The exhaust can get extremely hot and may cause burns.

Step 2: Remove the Stock Exhaust System

1. Locate the exhaust connections.
   Crawl under the car and locate the bolts connecting the stock exhaust system to the catalytic converter. These bolts can often be rusted or stuck, so apply penetrating oil if needed.
2. Unbolt the exhaust system.
   Use a socket wrench to remove the bolts at the exhaust flange (where the exhaust meets the catalytic converter). Keep these bolts handy in case your new performance exhaust requires reusing them.
3. Remove the exhaust from the hangers.
   Exhaust systems are usually held in place by rubber hangers. Use your hands or an exhaust hanger removal tool to gently slide the hangers off, allowing the old exhaust to be removed. It may be helpful to have an extra set of hands to support the exhaust system as you remove it.

Step 3: Install the New Performance Exhaust

1. Position the New Exhaust
   Begin by positioning the new performance exhaust system under the vehicle. If it’s a cat-back system, line it up with the catalytic converter and ensure all sections are oriented correctly.
2. Attach the exhaust to the hangers.
   Slide the exhaust pipes into the rubber hangers that held the original system in place. Make sure the exhaust system is fully supported before proceeding.
3. Bolt the new exhaust in place.
   Connect the exhaust flange to the catalytic converter using the bolts you saved earlier (or the new ones provided with your exhaust system). Use a torque wrench to tighten the bolts according to the manufacturer’s recommended specifications to avoid leaks or loose connections.

Step 4: Double-Check Your Work

1. Check for leaks.
   Before lowering the car, double-check all connections, especially at the flange, to ensure everything is secure and tightened. Make sure the exhaust hangers are properly supporting the system and that the exhaust isn’t hanging too low or touching any other parts of the vehicle.
2. Test the exhaust
   Start the engine to check for any exhaust leaks or rattling. Listen for abnormal sounds that could indicate loose bolts or poor connections.

Step 5: Lower the Vehicle

Once you’re satisfied that everything is secure and functioning properly, use the jack to carefully lower the vehicle back to the ground. Remove the jack stands or ramps and park the vehicle on a flat surface.

Step 6: Enjoy your upgraded performance exhaust

With the new performance exhaust installed, you should notice an improvement in both sound and performance. Take your 2018 Hyundai Elantra SEL for a drive to fully experience the enhanced sound and throttle response. A performance exhaust not only boosts horsepower and torque but also gives your car a sportier, more aggressive tone.
