Product Description
The WALKER 18925 SoundFX® Exhaust Muffler is engineered as a premium, direct-fit replacement designed to restore factory-style sound and exhaust performance on select Chrysler and Dodge models. Built from 100% aluminized steel, this muffler offers greater corrosion resistance and longer service life than standard low-carbon steel units.
Internal partitions, mechanically joined tubes, and spun-locked heads allow thermal expansion and contraction without distortion—enhancing durability and overall structural integrity. Louvered OE-style tubes reduce radiated noise for a refined factory-like sound profile, while the internal drainage system helps protect against moisture accumulation.
With OE-style hangers, brackets, and pipe routings, the 18925 installs easily as a bolt-on replacement, requiring no welding or custom fabrication. Designed and tested to extend muffler life, this SoundFX® muffler delivers dependable performance and OE-like acoustics.
