Fitment and application details
Compatible with 1994-1995 Chevrolet C1500 and K1500, and 1994-1995 GMC C1500 and K1500 when the welded assembly requires replacement of all required parts. It also fits 1994-1995 Chevrolet C2500, Chevrolet K2500, GMC C2500, and GMC K2500 below 8500 lb GVW. This part cross-references Walker 48452 for the same application.
Built for exhaust repair on Chevrolet C1500, Chevrolet K1500, GMC C1500, and GMC K1500 trucks, Walker 45456 helps restore the correct pipe section in the exhaust system while maintaining the specified flange and pipe dimensions.
What this exhaust pipe helps address
- Rust-through or corrosion in the original exhaust pipe
- Cracked or leaking pipe sections at the flange connection
- Damaged exhaust routing on the listed Chevrolet and GMC trucks
- Fitment issues caused by replacing only part of a welded assembly
Installation notes and tips
Verify the vehicle’s year, make, model, and GVW before ordering. For welded assemblies on the listed C1500 and K1500 applications, replace all required parts rather than only one section. Confirm the 2.75-inch inlet and outlet dimensions and the 2-bolt welded flange configuration during installation.
