Exhaust Muffler Overview

AP Exhaust 3269 is a Challenge series exhaust muffler built for heavy-duty Chevrolet and GMC truck applications. It uses an oval, baffled design with aluminized steel construction and OE-comparable sound level for direct replacement service.

Key Features

  • Aluminized steel body for corrosion resistance in exhaust service
  • Baffled muffler design for controlled exhaust flow and sound
  • Oval body shape with center inlet and dual pipe outlets
  • 2.5-inch inlet and 2.25-inch outlet sizing
  • Challenge series muffler for truck exhaust replacement work
  • AP Exhaust 3269 for Chevrolet C2500, K2500, and related GMC applications

Detailed Description

AP Exhaust 3269 is an exhaust muffler for 1988-1995 Chevrolet and GMC C/K truck platforms, including Chevrolet C2500, Chevrolet K2500, GMC C2500, and GMC K2500 applications listed in the fitment data. The muffler uses a 22-inch body length, 26-inch overall length, and a regular-grade aluminized steel shell to match common service replacement needs on these trucks. Its center inlet, dual left-center/right-center outlets, and baffled internal layout support OE-comparable exhaust tone while maintaining the dimensions needed for the specified applications. This part number, 3269, is listed across multiple Chevrolet and GMC heavy-duty truck fitments, including models with 2.5-inch muffler inlet requirements.

The Challenge series is AP Exhaust’s truck-focused muffler line for replacement service where a conventional oval muffler layout and controlled sound level are required. For buyers searching for a Chevrolet C2500 muffler, GMC K2500 exhaust muffler, or AP Exhaust 3269 replacement, this part is listed for the applications shown below.

What It Is Used For

  • Replacing a worn or rusted muffler on listed Chevrolet and GMC trucks
  • Restoring exhaust sound control after muffler failure
  • Addressing exhaust leaks caused by a damaged muffler body
  • Replacing a welded OE muffler assembly with a service muffler
  • Matching 2.5-inch inlet applications in the listed truck fitments

Installation Notes and Tips

Verify inlet and outlet sizing, body length, and outlet routing before installation. Fitment notes include several GVW-specific applications and exceptions for closed coupled exhaust systems, so confirm the exact vehicle configuration against the fitment list before ordering. This part is listed for Chevrolet C2500, Chevrolet K2500, GMC C2500, and GMC K2500 applications, and the part number 3269 should be matched to the vehicle’s exhaust layout and notes.

Quality Assurance

AP Exhaust 3269 is built with aluminized steel and a baffled internal design for service replacement use on the listed Chevrolet and GMC truck applications. The Challenge series designation identifies the product line used for these heavy-duty exhaust muffler replacements.
