Detailed Description

This Walker exhaust tail pipe is engineered for select 1987-1990 Chevrolet G10, G20, and G30, as well as GMC G1500, G2500, and G3500 vans. It is a direct-fit exhaust tail pipe with a 3-inch pipe connection at both ends, designed to replace OE split-design routing where specified. The aluminized finish helps resist exhaust system wear, while the formed steel construction supports consistent fitment during replacement work. This part cross-references 64722 for the same application.

What This Part Helps Address

Damaged or rusted tail pipe sections
Exhaust leaks caused by corrosion or failed pipe sections
Fitment issues when replacing OE split-design routing on select GM vans
Restricted exhaust flow from bent or deteriorated tail pipe tubing
Noise from a compromised rear exhaust section

Installation Notes and Tips

Compatible With 1987-1990 Chevrolet G10, G20, and G30, and 1987-1990 GMC G1500, G2500, and G3500 applications listed above. Review the vehicle notes carefully before installation, especially where the original system uses a split design, a single catalytic converter, light-duty emissions equipment, or welded assembly components. Verify inlet and outlet diameter match the existing exhaust connection points before assembly. Walker 45427 is a specific-fit replacement, so alignment should be checked against the existing exhaust routing prior to final tightening or welding.

Quality Assurance

Walker manufactures this pipe with precision benders and fixture checks to help ensure accurate fitment during installation. The aluminized steel construction and controlled forming process support consistent replacement quality for select Chevrolet and GMC exhaust systems.
