Installation Notes and Tips
Confirm left-side fitment before ordering, since this Walker 42123 pipe is specific to the listed Chevrolet applications and excludes high-performance Bel Air models. On Impala applications, verify the dual-exhaust configuration noted in the fitment data. Match the 2-inch inlet and outlet dimensions to the existing exhaust system before installation, and inspect adjoining hangers, clamps, and mating pipes for wear or corrosion.
Quality Assurance
Walker manufactures this pipe from aluminized steel and uses precision bending with fixture checking to help maintain dimensional accuracy and a proper fit for the listed Chevrolet applications.
