Detailed Description

ATP Parts 101273 is an OE-style exhaust manifold made to replace a damaged factory manifold and restore normal exhaust routing.

This manifold is intended to correct that failure point and return the exhaust system to proper operation. It is a fitment-based replacement for applications such as the Buick LeSabre, Buick Park Avenue, Chevrolet Impala, Pontiac Bonneville, and Pontiac Grand Prix, along with other listed models.

This part cross-references OE-style applications for the same vehicle coverage, including 674540 and 1390432.
