Detailed Description

Walker 40299 is an exhaust Y pipe engineered from aluminized steel with a 0.054-inch wall thickness and a 18.375-inch overall length. Its compression bend type, dual inlet layout, and pipe connection outlet are configured for the exhaust geometry used on the listed GM vehicles. This makes it a direct replacement option when restoring proper exhaust flow and connection integrity on a Chevrolet Caprice, Buick Roadmaster, or related fitment.

The pipe is manufactured with precision benders and checked in fixtures to help maintain dimensional consistency. That attention to fit is important when replacing a worn or damaged Y pipe, especially on applications where exhaust alignment and flange sealing must match the original layout. Part number 40299 is also cross-referenced to AP Exhaust 93980 for the same application.
