Preparation Steps

Proper preparation is crucial to ensure a smooth and safe installation. Follow these steps carefully before removing the existing exhaust system:

Vehicle Positioning and Safety

  • Park your Dodge Challenger on a flat, level surface—preferably concrete or asphalt.
  • Engage the parking brake and place wheel chocks behind the front wheels to prevent rolling.
  • Use a floor jack to lift the rear of the vehicle, then securely position jack stands under the designated lift points on the frame. Never rely solely on the jack for support.
  • Wear safety glasses to protect your eyes from dirt and debris, and gloves to protect your hands from sharp edges and heat.
  • Allow the exhaust system to cool completely if the vehicle was recently driven to avoid burns.

Familiarize Yourself with the Exhaust Layout

Take a few minutes to inspect your Challenger’s current exhaust system. Note the locations of clamps, hangers, bolts, and connections to the catalytic converters and mufflers. Photographing the arrangement can serve as a helpful reference during reinstallation.

Removing the Factory Exhaust System

The first major step is to remove the stock exhaust components carefully. Follow these detailed instructions:

Step 1: Apply Penetrating Lubricant

Spray penetrating lubricant generously on all exhaust bolts, nuts, and clamp points. Allow the lubricant to soak for 10-15 minutes to help loosen any rusted or seized fasteners, which are common on older vehicles.

Step 2: Disconnect Exhaust from Catalytic Converter

Using the appropriate socket or wrench, begin loosening the bolts where the exhaust connects to the catalytic converters. If your model features flange connections, remove the bolts; if it has clamps, loosen and slide them off.

Step 3: Remove Exhaust Hangers

The exhaust system is supported by rubber hangers attached to metal hooks on the vehicle frame. Use a pry bar or carefully use your hands to slide the hangers off the hooks. Applying lubricant can ease removal.

Step 4: Lower and Remove the Old Exhaust

Once disconnected from the catalytic converters and hangers, gently lower the exhaust system. It may be heavy and awkward, so having a helper assist in this step is highly recommended to avoid injury or damage to the vehicle.

Step 5: Inspect Components

With the old exhaust removed, inspect the catalytic converters and mounting points for any damage or rust that might require attention before installing the new system.

Installing the Corsa Xtreme Exhaust System

With the old system removed and the area prepared, you can proceed with installing your new Corsa Xtreme Exhaust.

Step 1: Assemble the Components

Lay out all the parts from the Corsa Xtreme kit. Identify each piece and hardware packet, matching them with the installation instructions provided by Corsa. Pre-assemble sections of the exhaust as recommended to simplify installation under the vehicle.

Step 2: Position the Exhaust

Starting at the catalytic converter connection, carefully lift the exhaust components into place. Align the pipe flanges or clamps with the corresponding mounting points. Be sure the exhaust flow direction matches the markings or instructions, as incorrect installation can affect performance.

Step 3: Attach the Exhaust to the Catalytic Converter

Secure the connection using the supplied clamps or bolts. Apply anti-seize compound to the fasteners before tightening to prevent future rust and make removal easier if needed. Use a torque wrench to tighten bolts to the manufacturer’s specified torque values, typically found in the installation manual.

Step 4: Mount the Exhaust Hangers

Slide the rubber hangers onto the exhaust hooks carefully. Ensure the exhaust is properly supported and not hanging too low or touching any part of the chassis or suspension components to avoid rattling or damage.

Step 5: Tighten All Connections

Work your way along the entire exhaust system, tightening all clamps, bolts, and fasteners securely. Double-check each connection for tightness and proper alignment. The exhaust should have a small amount of play to accommodate thermal expansion but should not be loose.

Final Checks and Testing

Before lowering your vehicle and starting the engine, perform these crucial checks:

  • Verify that all hardware is tightened to specification.
  • Ensure the exhaust system is centered and has adequate clearance from the ground and vehicle components.
  • Check that the exhaust hangers are secure and intact.

Once confident, lower your Dodge Challenger carefully from the jack stands. Start the engine and listen attentively for any unusual sounds such as leaks, rattles, or excessive drone. The Corsa Xtreme exhaust should produce a deep, aggressive tone that is unmistakably performance-oriented but free from cabin drone thanks to its RSC technology.

If you detect any leaks or loose fittings, safely turn off the engine and inspect the system, tightening or adjusting as needed.

Post-Installation Care and Maintenance

To maintain optimal performance and longevity of your new exhaust system, follow these maintenance tips:

  • Regular Inspections: Periodically check exhaust clamps, hangers, and pipes for signs of wear, corrosion, or looseness.
  • Cleaning: Clean the exterior of the exhaust with appropriate stainless steel cleaners to preserve its finish and prevent rust.
  • Heat Cycles: After installation, allow the exhaust system to go through multiple heat cycles (drive the vehicle and allow it to cool) to help components settle and seal properly.
  • Address Issues Promptly: Address any noises, vibrations, or leaks as soon as possible to prevent damage to the exhaust or vehicle.
