  • Exhaust hanger pliers (optional): Useful for removing and installing exhaust hangers without damaging rubber mounts.

Preparation and Safety Precautions

Before beginning the installation, it’s essential to prepare your workspace and vehicle properly. Follow these steps to ensure safety and efficiency:

  • Park on a flat, level surface: This prevents the vehicle from rolling or shifting while it’s elevated.
  • Engage the parking brake: Adds an extra layer of security to keep your Silverado stationary.
  • Allow the exhaust system to cool: Exhaust components can become extremely hot after driving. Wait several hours or overnight to avoid burns.
  • Gather all tools and materials: Having everything ready avoids interruptions and minimizes risks.
  • Wear appropriate safety gear: Use gloves to protect hands from sharp edges and debris, and safety glasses to shield your eyes from rust particles or debris.
  • Lift the vehicle safely: Use a quality jack to raise the rear of the Silverado and secure it with jack stands placed under the manufacturer-recommended lifting points. Never rely solely on a jack when working underneath a vehicle.

Step 1: Removing the Old Exhaust System

Removing the factory exhaust system can be challenging due to rust, corrosion, and tight fittings. Follow these tips for a smooth removal process:

  • Start by spraying penetrating oil: Liberally apply WD-40 or a similar penetrating oil to all bolts, clamps, and hangers. Let it soak for 15-20 minutes to break down rust and corrosion.
  • Disconnect the exhaust from the catalytic converter: Use your socket set to remove the bolts securing the exhaust flange to the catalytic converter. Be cautious as these bolts can be tightly fastened or rusted.
  • Remove exhaust hangers: Use exhaust hanger pliers or carefully pry with a flathead screwdriver to detach the exhaust from rubber hangers. This allows the exhaust to hang freely for removal.
  • Support the exhaust: As you loosen bolts and clamps, support the exhaust system with one hand or a floor jack to prevent it from dropping suddenly, which could cause injury or damage.
  • Remove the muffler and mid-pipe sections: Once hangers and bolts are free, carefully slide the exhaust system out from under the vehicle. Some sections may require gentle twisting or tapping with a rubber mallet.
  • Inspect mounting points: Take note of any damaged or heavily corroded hangers or flanges that may need replacement during installation.

Step 2: Preparing the Borla Exhaust System for Installation

Before installing, it’s important to inspect and prepare your new Borla exhaust components:

  • Unpack and organize parts: Lay out all components in the order they will be installed. Verify that all parts, gaskets, and clamps are included according to the Borla instruction manual.
  • Compare old and new parts: Check dimensions and fitment points to ensure compatibility with your Silverado’s model year and engine size.
  • Pre-fit components: Temporarily assemble sections to familiarize yourself with the system and identify any potential fitment issues.
  • Apply anti-seize lubricant: Coat bolts and fasteners lightly to prevent future rusting and ease future maintenance.
  • Replace worn hangers or mounts: If any exhaust hangers or mounts from your Silverado were damaged or excessively worn during removal, replace them to ensure stability.

Step 3: Installing the Borla Exhaust System

Installation of the new Borla exhaust system should be approached methodically, starting from the front (catalytic converter connection) and working toward the rear. Follow these detailed steps:

  • Attach the front pipe: Position the front pipe to the catalytic converter flange. Use the new gasket provided and loosely tighten the flange bolts. This allows for adjustments during alignment.
  • Install mid-pipe and resonator (if applicable): Connect the mid-pipe section to the front pipe, securing with clamps but leaving bolts slightly loose for alignment.
  • Connect muffler and tailpipe sections: Slide the muffler and tailpipe into position, using the rubber hangers to support the system. Ensure exhaust tips are properly aligned with the rear bumper cutouts for a professional look.
  • Check clearance: Verify that the entire exhaust system is clear of fuel lines, brake lines, suspension components, and the vehicle’s underbody to prevent rattling, heat damage, or vibrations.
  • Adjust alignment: Shift pipes and mufflers as needed to achieve optimal fit and clearance.
  • Tighten clamps and bolts: Using a torque wrench, tighten all bolts and clamps to Borla’s recommended specifications. Proper torque prevents leaks and ensures longevity.
  • Inspect hangers: Confirm that all exhaust hangers are securely holding the system without excessive movement.

Step 4: Final Checks and Testing

Once the Borla exhaust system is installed, perform thorough checks before lowering your Silverado and taking it for a test drive.

  • Lower the vehicle carefully: Remove jack stands and slowly lower the truck back to the ground.
  • Start the engine: Listen closely for any exhaust leaks, rattles, or unusual noises. Pay attention to the exhaust note to appreciate the Borla system’s signature sound.
  • Inspect for leaks: Visually inspect all joints and clamp areas for escaping gases. You can also use a soapy water solution sprayed on joints—bubbles indicate leaks.
  • Tighten if necessary: If you detect leaks or loose components, shut off the engine and tighten clamps or bolts accordingly.
  • Take a test drive: Drive your Silverado under various conditions—idling, acceleration, cruising, and deceleration—to ensure the exhaust system performs smoothly without vibration or noise issues.
  • Recheck after initial drive: After the first few miles, re-inspect all fasteners and clamps, as thermal expansion can sometimes cause components to loosen initially.

Maintenance Tips for Your Borla Exhaust System

To maximize the lifespan and performance of your new Borla exhaust system, follow these maintenance recommendations:

  • Regular inspections: Periodically check for corrosion, loose clamps, or damage, especially after off-road use or harsh weather.
  • Clean exhaust tips: Use mild soap and water or specialized stainless steel cleaners to keep tips looking sharp and prevent discoloration.
  • Avoid prolonged exposure to road salt: If you live in regions with salted roads, rinse the undercarriage frequently during winter months to reduce corrosion.
  • Address leaks promptly: Any signs of exhaust leaks should be repaired immediately to maintain system efficiency and safety.
  • Use quality replacement parts: Should you need to replace clamps or gaskets, use OEM or Borla-approved parts to maintain system integrity.

Common Installation Challenges and How to Overcome Them

While Borla exhaust systems are designed for direct fitment, some Silverado owners may encounter challenges during installation. Here are a few common issues and solutions:

  • Stubborn rusty bolts: If bolts won’t budge despite penetrating oil, try applying heat with a propane torch carefully or use impact tools for added torque. Always wear protective gear during this process.
  • Misaligned exhaust hangers: If hangers do not align perfectly, use adjustable exhaust hanger brackets or replace rubber mounts with slightly flexible aftermarket versions.
  • Excessive exhaust rattle: Check for loose clamps or contact points against the frame or suspension. Adding exhaust wrap or rubber insulators can help dampen vibrations.
