Product Description

The WALKER 18853 SoundFX® Exhaust Muffler is engineered as a direct-fit replacement for heavy-duty Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins diesel engine. Built from 100% aluminized steel, this muffler significantly improves durability and corrosion resistance compared to standard low-carbon steel.

Its robust design includes mechanically joined internal tubes, spun-locked heads, and an integrated internal drainage system to reduce moisture buildup—common in diesel exhaust systems. The result is a long-lasting, reliable muffler capable of withstanding thermal stress and harsh operating conditions.

OE-style hangers and pipe routing ensure simple, bolt-on installation without fabrication. Louvered internal tubes deliver a controlled, factory-like exhaust tone suitable for diesel applications while maintaining optimal flow characteristics.

Key Features

  • Aluminized Steel Construction for corrosion resistance and long service life

  • Direct-Fit Bolt-On Replacement with OE-style hangers

  • Louvered Tubes provide factory-style sound control

  • Durable Spun-Locked Heads minimize distortion during heat cycles

  • Internal Drainage System reduces moisture accumulation

  • Designed and Tested for extended performance in heavy-duty applications
