Why Upgrade the Exhaust System on Your Veloster N?

The factory exhaust on the 2019 Veloster N is designed to balance emissions, noise regulations, and fuel efficiency, which often means some performance potential is left untapped. Upgrading to a high-performance exhaust system can provide several key benefits:

  • Increased Horsepower and Torque: Aftermarket exhaust systems reduce exhaust gas restriction, allowing the engine to breathe more freely and produce more power.
  • Enhanced Exhaust Sound: Many enthusiasts appreciate a deeper, more aggressive exhaust note that reflects the sporty nature of the Veloster N.
  • Weight Reduction: Some performance exhaust systems use lighter materials like stainless steel or titanium, helping to reduce overall vehicle weight.
  • Improved Aesthetics: Upgraded exhaust tips and polished finishes can add a visually appealing, customized look to the rear of your vehicle.
  • Potential Fuel Efficiency Gains: By improving the engine’s efficiency, some drivers notice slight improvements in fuel economy during spirited driving.

Before starting the upgrade process, it’s important to consider your goals—whether you want maximum performance, a louder exhaust sound, or just a subtle improvement—and choose a system that fits those needs. Popular brands compatible with the 2019 Veloster N include Borla, MagnaFlow, Injen, and Hyundai’s own N Performance parts.

Preparation: Selecting the Right Exhaust System

When choosing an aftermarket exhaust, consider the following factors:

  • Material: Stainless steel is common for its durability and corrosion resistance. Titanium systems are lighter but more expensive.
  • Configuration: Options include cat-back exhausts (replacing everything from the catalytic converter back), axle-back systems (replacing mufflers and tips), and turbo-back exhausts (replacing everything from the turbocharger onwards).
  • Sound Level: Some systems are designed to be louder and more aggressive, while others maintain a refined tone.
  • Compatibility: Ensure the exhaust system is specifically designed for the 2019 Hyundai Veloster N to avoid fitment issues.
  • Legal Considerations: Check local noise and emissions regulations to ensure your chosen exhaust system is street-legal.

Tools and Materials Needed

  • New performance exhaust system compatible with 2019 Veloster N
  • Socket wrench set (metric sizes)
  • Jack and jack stands or ramps
  • Penetrating oil (such as WD-40 or PB Blaster) for loosening rusted bolts
  • Safety glasses and gloves to protect your eyes and hands
  • Exhaust gasket(s) if required by your new exhaust system
  • Torque wrench for precise bolt tightening
  • Rubber mallet (optional, for gentle persuasion of tight parts)
  • WD-40 or anti-seize compound for bolts during reassembly

Step-by-Step Installation Process

1. Prepare Your Vehicle

Begin by parking your Veloster N on a flat, stable surface. Engage the parking brake to ensure the vehicle doesn’t move during the installation. To gain access to the exhaust system underneath the vehicle, you’ll need to lift the rear of the car using a jack. Place the jack pads under the car’s designated lift points (consult the owner’s manual for locations), then raise the vehicle. Secure it safely on jack stands to prevent any risk of falling. Never rely solely on the jack to hold the car in place.

Safety Tip: Wear safety glasses and gloves throughout the process to protect yourself from debris, rust, and sharp edges on exhaust components.

2. Remove the Stock Exhaust System

Start the removal process at the rear by loosening and removing the bolts securing the muffler to the rest of the exhaust assembly. Spray penetrating oil liberally on all bolts and mounting points to ease removal, especially if they show signs of rust. Allow the oil to soak for several minutes.

Using your socket wrench set, carefully unbolt each section of the exhaust, moving forward from the muffler toward the catalytic converter. The exhaust is typically held in place by rubber hangers which you can pry off using a flat-head screwdriver or exhaust hanger removal tool. Be patient and avoid forcing any components to prevent damage.

If you encounter stubborn bolts or seized nuts, apply more penetrating oil and allow additional time for it to work. In severe cases, a breaker bar may be needed for extra leverage.

3. Inspect and Clean Exhaust Mounting Points

Once the old exhaust system is removed, take the opportunity to inspect the exhaust hangers, mounting brackets, and surrounding areas for any signs of wear, cracks, or damage. Replace any worn hangers to ensure the new system is securely supported.

Clean any rust, dirt, or debris from the exhaust flanges and mounting surfaces using a wire brush or sandpaper. This step promotes a proper seal and prevents future leaks. Also, check the condition of the exhaust gaskets; replace them if they look worn or damaged.

4. Install the New Exhaust System

Carefully unpack the new exhaust system and verify that all components are present as per the manufacturer’s instructions. Begin installation by loosely assembling the system starting from the front (near the catalytic converter) and working your way back to the muffler.

Position new exhaust gaskets at the flange connections to ensure a tight seal and prevent leaks. Slide the new pipes into place, aligning them with the hangers and mounting points. Do not fully tighten bolts at this stage; loosely securing the components allows for final alignment adjustments.

Ensure that the exhaust tips are oriented properly and that there is sufficient clearance between the exhaust and the vehicle’s underside to prevent rattling or contact with suspension components.

5. Align and Tighten the Exhaust System

With all components loosely assembled, double-check the alignment of the exhaust system. Adjust as necessary to ensure the exhaust tips protrude evenly from the rear bumper cutouts and that the pipes do not hang too low or come into contact with any parts of the vehicle.

Using a torque wrench, tighten all bolts and clamps to the manufacturer’s recommended torque specifications. Proper torque prevents exhaust leaks and ensures the system stays secure under all operating conditions.

Apply a small amount of anti-seize compound to the threads to make future removal easier and prevent corrosion.

6. Lower the Vehicle and Conduct Post-Installation Testing

Remove the jack stands and carefully lower your Veloster N back to the ground. Start the engine and listen closely for any unusual noises such as rattling, ticking, or exhaust leaks. Also, check visually for any signs of exhaust gases escaping at the joints or connections.

A properly installed exhaust system should provide a noticeable improvement in sound quality—deeper, throatier, and more aggressive—without excessive drone or vibration inside the cabin.

Take the car for a short test drive to confirm that there are no rattles or vibrations and that the exhaust flow feels smooth and responsive. Pay attention to turbo spool characteristics and throttle response, as these can often improve with a freer-flowing exhaust.

Additional Tips and Considerations

  • Professional Assistance: If you are uncomfortable with lifting the vehicle or dealing with stubborn bolts, consider seeking help from a professional mechanic or exhaust specialist.
  • Heat Shielding: Some aftermarket exhaust systems may require adjustments to heat shields or additional insulation to protect nearby components from excessive heat.
  • Engine Tuning: After upgrading the exhaust, consider an ECU tune or flash to fully optimize performance gains. Many aftermarket exhausts paired with proper tuning can significantly increase horsepower and torque.
  • Warranty and Emissions: Keep in mind that modifying the exhaust may affect your vehicle’s warranty and emissions compliance. Always check local laws and ensure your upgrade is street-legal.
  • Regular Maintenance: Periodically inspect the exhaust system for loose bolts, rust, or damage to maintain optimal performance and safety.
