Detailed Description

Walker 43697 is an exhaust pipe engineered for direct-fit replacement on select Chevrolet and GMC C/K-series trucks, Suburban models, and related R/V applications. The pipe uses aluminized steel and precision bending to match the intended routing and connection points, helping support a cleaner installation on vehicles such as the Chevrolet C10, Chevrolet C20, GMC C1500, and GMC C2500. This part number is also listed for several 1987 R10, R20, V10, R1500, R2500, and V1500 applications.

Because fitment varies by year, emissions equipment, and exhaust configuration, verify the notes for your vehicle before ordering Walker 43697. The listed applications include cut-to-fit, single catalytic converter, dual exhaust, and heavy-duty configurations.
