AP Exhaust 8792 Exhaust Flange Overview

This AP Exhaust exhaust flange is listed for a wide range of classic GM full-size and intermediate vehicles, including Buick Roadmaster, Cadillac Fleetwood, and Chevrolet Caprice applications.

Detailed Description

AP Exhaust 8792 is a replacement exhaust flange used at the connection point between exhaust components. The listed dimensions help confirm fitment when matching flange spacing, mounting hole size, and pipe interface requirements. This makes it a practical choice for exhaust service on vehicles such as Buick Roadmaster, Cadillac Fleetwood, and Chevrolet Caprice models where the original flange has corroded, warped, or no longer seals correctly.

Fitment coverage includes 1994-1996 Buick Roadmaster left and right dual exhaust, 1994-1996 Cadillac Fleetwood left and right dual exhaust, and 1994-1996 Chevrolet Caprice left and right dual exhaust. Additional coverage extends across earlier Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac applications from 1979 through 1996, including several dual-bed monolithic converter and converter-specific configurations. AP Exhaust 8792 is also referenced for Chevrolet Caprice exhaust flange replacement and Cadillac Fleetwood exhaust flange service on the listed applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Repair

  • Exhaust leaks at a flange joint
  • Rust-damaged or distorted flange connections
  • Loose exhaust mating surfaces
  • Failed sealing points during exhaust system service
  • Fitment issues when replacing a worn OEM-style flange on listed GM vehicles

Installation Notes and Tips

Verify the flange dimensions against the existing part before installation, especially bolt-to-bolt length, inside diameter, and mount hole diameter. Confirm the vehicle position and exhaust configuration shown in the fitment list, including left, right, and N/A applications, as well as notes such as dual exhaust or converter-specific setups. For best results, inspect adjoining pipes, fasteners, and sealing surfaces before assembly.

Quality Assurance

AP Exhaust is a recognized exhaust-system brand with coverage across replacement brackets, flanges, and hangers. Part number 8792 is cataloged with detailed dimensional data and vehicle-specific fitment references to support accurate exhaust repair selection.
