Walker 45521 Exhaust Pipe for GM B-Body Left Side

Walker 45521 is a specific-fit exhaust pipe built for select 1994-1996 Buick Roadmaster, Chevrolet Caprice, and Chevrolet Impala applications on the left side. It uses aluminized steel construction and precision-formed bends to support a direct-fit replacement with accurate alignment.

Key Features

  • Aluminized steel construction for corrosion resistance and durability
  • Specific-fit design for select GM full-size rear-wheel-drive applications
  • 2.25-inch inlet and 2.25-inch outlet diameter
  • 2-bolt loose flange with spherical flare inlet connection
  • Pipe connection outlet for straightforward exhaust system integration
  • Precision-bent and fixture-checked for fit consistency
  • Walker 45521 exhaust pipe for left-side replacement service

Detailed Description

This Walker exhaust pipe is engineered for 1994-1996 Buick Roadmaster, 1994-1996 Chevrolet Caprice with dual exhaust, and 1994-1996 Chevrolet Impala left-side applications. The 55.625-inch pipe length and 2.25-inch diameter sizing support proper routing in the exhaust system, while the aluminized finish helps the steel resist everyday exhaust heat and corrosion exposure. Walker 45521 is a practical choice when replacing a worn or damaged left-side exhaust pipe on these GM models.

This part cross-references part number 58358 for the same application.

What It Helps Fix

  • Exhaust leaks caused by rusted or cracked pipe sections
  • Broken or misaligned left-side exhaust routing
  • Noise from damaged exhaust tubing or failed joints
  • Fitment issues after replacing a welded exhaust assembly
  • Restricted exhaust flow from deteriorated pipe sections

Installation Notes and Tips

Compatible With 1994-1996 Buick Roadmaster, left; 1994-1996 Chevrolet Caprice, left with dual exhaust; and 1994-1996 Chevrolet Impala, left. If the original system uses a welded assembly, replace all required related parts during service to restore proper alignment and sealing. Verify flange style, pipe diameter, and routing before installation.

Quality Assurance

Walker manufactures this pipe with precision benders and fixture checking to help maintain consistent fitment and installation accuracy. The aluminized steel construction supports long-term service in exhaust applications.
