ATP Parts 101080 Left Exhaust Manifold

ATP Parts 101080 is a left exhaust manifold for a wide range of Chevrolet, GMC, Buick, Oldsmobile, Pontiac, and Cadillac-era applications. It restores the exhaust path by replacing a cracked or warped manifold that can leak hot exhaust gases into the engine bay.

This ATP exhaust manifold is built to match original fit and function for direct replacement service on many 1976-1988 vehicles, including Chevrolet G20, Chevrolet P30, and GMC P2500 applications.

Key Features

• Left-side exhaust manifold replacement for select GM vehicles
• OE-style fit and function for manifold repair
• Helps restore proper exhaust gas routing from the engine to the exhaust system
• Designed for applications with California emissions and A.I.R. configurations where listed
• Part number 101080 for application matching and catalog lookup

Detailed Description

ATP Parts 101080 is engineered as a direct replacement exhaust manifold for the left side of the engine. It is intended for vehicles where the original manifold has cracked, warped, or begun leaking at the flange or gasket surface. By restoring the exhaust seal, this manifold helps return the exhaust system to proper operation and reduces the risk of exhaust gases entering the passenger compartment.

Fitment includes many classic GM platforms such as Chevrolet G10, G20, G30, P20, P30, Camaro, Corvette, Nova, and Monte Carlo, along with GMC G1500, G2500, G3500, P2500, and P3500 models. The part number 101080 is also referenced across multiple interchange listings for catalog verification.

This part cross-references AMS Automotive 6168 for the same application.

What It Helps Fix

• Exhaust leaks from a cracked or warped manifold
• Ticking or puffing noises at the manifold area
• Hot exhaust escaping into the engine compartment
• Failed gasket sealing at the cylinder head or exhaust flange
• Loss of proper exhaust routing on left-side applications

Installation Notes and Tips

• Confirm left-side placement before ordering.
• Match your vehicle’s emissions configuration, including California emissions and A.I.R. hole notes where listed.
• Inspect the cylinder head surface, gasket face, studs, nuts, and washers during installation.
• Check for flange alignment and exhaust pipe fitment before final tightening.
• Use the vehicle-specific notes in the fitment list to verify exact application coverage.
