Whether you’re an enthusiast looking for a sportier sound or aiming to extract more performance from your turbocharged engine, installing the Stinger Street Series Exhaust can be a rewarding project.

This comprehensive guide covers everything you need to know to install the exhaust system safely and efficiently. From the necessary tools and preparation steps to detailed installation instructions and maintenance advice, you’ll be equipped to perform the upgrade with confidence.

Understanding the Benefits of the Stinger Street Series Exhaust

The Stinger Street Series Exhaust is engineered to optimize the Veloster N's factory exhaust setup. Key benefits include:

  • Improved Performance: By reducing exhaust backpressure and enhancing flow, the system can contribute to smoother turbo spool and increased horsepower and torque.
  • Enhanced Sound: The exhaust produces a more aggressive, sporty sound that enhances the driving experience without being excessively loud.
  • Quality Construction: Made from high-grade stainless steel, the system offers durability and resistance to corrosion, ensuring long-term reliability.
  • Custom Fit: Designed specifically for the Veloster N, the exhaust system fits precisely without the need for modifications.

Tools and Materials Needed

Before starting the installation, gather the following tools and materials to ensure a smooth process:

  • Socket Set and Ratchet: Essential for loosening and tightening bolts and clamps.
  • Jack and Jack Stands: To safely lift and support your vehicle off the ground.
  • WD-40 or Penetrating Oil: Helps loosen rusted or seized bolts for easier removal.
  • New Stinger Street Series Exhaust: The complete exhaust system including mid-pipe, muffler, and tailpipe.
  • Exhaust Gasket: Often required to ensure a proper seal between the catalytic converter and new exhaust.
  • Safety Gloves and Eye Protection: To protect yourself from sharp edges and debris during installation.
  • Torque Wrench: For precise tightening of bolts to manufacturer specifications.
  • Rubber Mallet: Useful for gently aligning exhaust components without causing damage.
  • Anti-Seize Compound: To prevent bolts from seizing in the future and facilitate easier removal later on.

Preparation

Proper preparation is critical to a successful exhaust installation. Follow these steps before removing the old exhaust:

  • Park on a Level Surface: Ensure your Veloster N is parked on a flat, stable surface to prevent any shifting while lifted.
  • Engage Parking Brake and Chock Wheels: This adds an extra layer of safety by preventing the vehicle from rolling.
  • Lift the Vehicle: Use a hydraulic jack to lift the car at manufacturer-recommended lift points. Place jack stands securely under the vehicle to support its weight.
  • Wear Safety Gear: Put on gloves and eye protection to safeguard against rust, dirt, and sharp edges.
  • Apply Penetrating Oil: Spray WD-40 or a similar product onto all exhaust bolts, clamps, and hangers. Allow it to soak for 10–15 minutes to loosen rust and corrosion.
  • Gather Parts and Double-Check Fitment: Lay out the new exhaust components and verify that all parts are included and match your vehicle’s model year.

Removing the Old Exhaust

Removing the factory exhaust requires care to avoid damaging surrounding components. Follow this detailed procedure:

  • Locate Exhaust Components: Crawl under the vehicle using a creeper or mat. Identify the exhaust system starting from the catalytic converter back to the muffler and tailpipe.
  • Disconnect Sensors: If your Veloster N has oxygen sensors installed near the exhaust, carefully unplug them or detach their wiring connectors to prevent damage.
  • Loosen Bolts and Clamps: Using your socket set and ratchet, begin loosening the bolts and clamps securing the exhaust to the catalytic converter and mid-pipe. Penetrating oil should have eased this process.
  • Remove Exhaust Hangers: The exhaust is suspended by rubber hangers. Use a pry bar or exhaust hanger removal tool to slide the hangers off the mounting points.
  • Lower the Exhaust Assembly: With all connections undone, carefully lower the old exhaust from beneath the vehicle. Assistance may be helpful to avoid dropping and damaging parts.
  • Inspect Exhaust Flanges and Pipes: Clean any rust or debris from the exhaust flanges on the catalytic converter to ensure a proper seal for the new gasket and exhaust.

Installing the Stinger Street Series Exhaust

Follow these steps to install your new Stinger Street Series Exhaust correctly:

  • Prepare Gaskets and Clamps: Place a new exhaust gasket at the flange connection between the catalytic converter and the new exhaust. Apply a thin layer of anti-seize compound on bolts to facilitate future removal.
  • Position the Exhaust System: Starting from the front, align the new exhaust system with the catalytic converter. Slide the mid-pipe into place and loosely secure the flange bolts.
  • Attach Hangers: Mount the exhaust hangers onto the rubber isolators to suspend the system. Ensure the exhaust is supported properly to avoid strain on the connections.
  • Align and Fit Components: Adjust the position of the exhaust so that the muffler and tailpipe sit evenly and do not contact the underbody or suspension parts. Use a rubber mallet to gently tap components into alignment if necessary.
  • Tighten Bolts and Clamps: Once satisfied with the fitment, tighten all flange bolts and clamps to the manufacturer’s torque specifications using a torque wrench. This prevents exhaust leaks and ensures secure installation.
  • Reconnect Sensors: Plug back any oxygen sensors or wiring harnesses unplugged during removal.
  • Double-Check Everything: Inspect all connections, hangers, and bolts to confirm they are secure and properly aligned.

Final Checks and Test Drive

After installation, perform these critical checks before driving your vehicle:

  • Lower the Vehicle: Carefully remove the jack stands and lower your Veloster N back to the ground.
  • Start the Engine: Listen closely for any exhaust leaks, rattling, or unusual noises which could indicate loose connections or misalignment.
  • Inspect for Vibrations: Feel for excessive vibration or contact between the exhaust and other parts of the vehicle.
  • Take a Test Drive: Drive the car under various conditions including idle, acceleration, and cruising. Pay attention to the exhaust tone and ensure there are no warning lights on the dashboard.
  • Recheck After Cooling: Once the vehicle has cooled down, re-inspect the bolts and clamps to ensure they remain tight.

Maintenance Tips for Longevity and Performance

Maintaining your Stinger Street Series Exhaust will help preserve its performance, sound quality, and appearance over time. Consider these tips:

  • Regular Inspections: Periodically check for signs of rust, corrosion, or damage to the exhaust pipes, muffler, and mounting hardware.
  • Tighten Clamps and Bolts: Vibrations from driving can loosen fasteners. Use a torque wrench to retighten as needed.
  • Clean the Exhaust Tips: Use metal polish and a microfiber cloth to keep the exhaust tips looking shiny and free of carbon buildup.
  • Avoid Harsh Environments: Whenever possible, avoid prolonged exposure to road salt or mud which can accelerate corrosion.
  • Check for Leaks: Listen for unusual exhaust noises and inspect joints for any signs of leaks or soot deposits.
  • Professional Servicing: If you notice performance drops or suspect exhaust damage, have a qualified technician inspect and service the system.

Additional Performance Upgrades to Complement Your New Exhaust

To maximize the benefits of the Stinger Street Series Exhaust, consider pairing it with other modifications tailored to the Hyundai Veloster N:

  • Cold Air Intake: Improves airflow into the engine, increasing horsepower and throttle response.
  • ECU Tune: Optimizes engine parameters for enhanced power and efficiency, especially when combined with upgraded exhaust components.
  • Performance Intercooler: Reduces intake air temperatures, helping maintain power during spirited driving.
  • Upgraded Downpipe: Further reduces exhaust restrictions, improving turbo spool and overall engine breathing.
