Preparation

Proper preparation is critical to a successful exhaust installation. Follow these steps to set yourself up for success:

  • Park on a Flat Surface: Choose a level area with ample lighting and space to work safely around your Corvette.
  • Engage the Parking Brake: This prevents the car from rolling while it is lifted.
  • Lift the Vehicle: Use a hydraulic jack to raise the front or rear of the Corvette as needed—typically, rear lift is sufficient for exhaust work. Securely position jack stands under manufacturer-recommended lift points to support the vehicle’s weight.
  • Wear Safety Gear: Put on gloves and goggles to protect your hands from sharp edges and your eyes from rust or debris.
  • Apply Penetrating Oil: Spray WD-40 or a similar product on all exhaust clamps, bolts, and hangers. Allow it to soak for 10–15 minutes to help loosen rust and corrosion, making removal easier.
  • Review the Bassani Installation Manual: Each Bassani exhaust kit includes manufacturer-specific instructions. Review these carefully to understand any nuances for your particular Corvette model.

Removing the Old Exhaust System

Carefully removing the factory exhaust is the next step. Follow these detailed instructions to prevent damage and facilitate a smooth installation of the new system:

  • Locate Exhaust Components: Crawl under the Corvette and identify all sections of the stock exhaust system, including the mufflers, mid-pipes, clamps, and hangers.
  • Loosen and Remove Clamps: Using the socket set or wrench, start loosening the clamps that connect the exhaust pipes. If bolts are rusted or stuck, apply additional penetrating oil and allow it to soak further.
  • Detach Exhaust Hangers: Exhaust hangers hold the system in place using rubber isolators. Use a pry bar or hanger removal tool to gently pop the hangers free without damaging them, as some may be reusable.
  • Remove Exhaust Sections: Once clamps and hangers are free, carefully lower each section of the exhaust. You may need a helper to support heavier components. Avoid banging pipes against the chassis to prevent damage.
  • Clean Mating Surfaces: Use a gasket scraper or wire brush to remove any old gasket material or rust from the exhaust flanges. A clean surface ensures a proper seal with the new Bassani system and prevents leaks.
  • Inspect Existing Hardware: Evaluate the condition of bolts and clamps. Consider replacing any that are severely corroded or damaged to ensure a secure fit for the new system.

Installing the Bassani Exhaust System

With the old exhaust removed and mating surfaces clean, it’s time to install your new Bassani system. Follow these steps carefully:

  • Test Fit Components: Before fully tightening anything, loosely assemble the Bassani exhaust sections under the vehicle. This allows you to check alignment and fitment with the factory mounting points.
  • Use Provided Gaskets: Place the new gaskets supplied with your Bassani kit between mating flanges to ensure a gas-tight seal.
  • Attach Clamps and Hangers: Secure each section with the clamps and hangers included in the kit. Hand-tighten clamps initially to allow for slight adjustments.
  • Align the Exhaust Tips: Position exhaust tips evenly, making sure they are centered and spaced properly relative to the rear bumper. This not only looks better but also prevents scraping or damage.
  • Tighten Bolts and Clamps: Using a torque wrench, tighten all bolts and clamps to the Bassani manufacturer’s recommended specifications. Proper torque is crucial to prevent leaks and ensure durability.
  • Apply Anti-Seize: Before final assembly, apply a thin layer of anti-seize lubricant to bolts and fasteners. This will make future removal easier and prevent corrosion.
  • Double-Check All Connections: Verify that every clamp, bolt, and hanger is secure and that the exhaust system has adequate clearance from the chassis and suspension components to prevent rattling or heat damage.

Final Checks and Testing

Once installation is complete, it’s important to perform thorough checks and testing to confirm everything is working properly:

  • Lower the Vehicle: Carefully remove the jack stands and lower your Corvette back onto the ground.
  • Start the Engine: Turn on the ignition and listen closely for any unusual noises such as hissing, rattling, or exhaust leaks.
  • Inspect for Leaks: With the engine running, visually check all connections and flanges for escaping exhaust gases. You may feel leaks by holding your hand near joints (without touching hot surfaces).
  • Tighten as Needed: If you detect any leaks or loose fittings, safely lift the vehicle again and tighten clamps or bolts as necessary.
  • Test Drive: Take your Corvette for a short drive, paying attention to the exhaust sound and overall vehicle performance. A properly installed Bassani exhaust should deliver a deeper, more aggressive tone without drone or rattling.
  • Re-Inspect After Test Drive: After your test drive, inspect the system once more. Heat cycles can sometimes cause minor shifts in alignment or loosen hardware.
