Key Features

• Universal fit exhaust muffler for custom and replacement applications
• 100% aluminized steel construction for longer service life than low-carbon steel
• Oval body shape with a regular-grade design
• Offset 2.5-inch inlet and center 2.25-inch outlet
• Mechanical interior joints and spun-locked heads for added durability
• Aluminized steel finish for a clean, corrosion-resistant appearance
• Walker SoundFX Universal line for quality acoustics and dependable construction

Product Details

Walker 18109 is a combination-style exhaust muffler with a 30-inch overall length, 22-inch body length, and 8.813-inch body width. The steel body uses an aluminized finish to improve durability, while the offset inlet and center outlet layout supports a wide range of exhaust routing needs. This makes it a strong option for older full-size vans, trucks, and classic passenger vehicles that require a universal muffler rather than a direct OE-shaped replacement.

This part cross-references Walker Exhaust 41962 for the same application. It is also associated with interchange part number 5568.

Common Problems This Muffler Can Address

• Rust-through or corrosion in an existing muffler
• Excessive exhaust noise from a damaged internal baffle
• Poor exhaust flow caused by a restricted muffler core
• Need for a universal replacement during custom exhaust repair
• Replacement needs on older Dodge, Ford, Chevrolet, GMC, Chrysler, and Plymouth vehicles

Installation Notes

Compatible With many older applications, including Fits 1990 Dodge D150, Fits 1975-1985 Ford E-350 Econoline, and Fits 1996 Chevrolet P30 when the listed notes and related part numbers are followed. Additional parts and modifications may be required depending on the vehicle, exhaust routing, catalytic converter setup, and GVW configuration.
