Description:

SOUND FX MUFFLER

Featuring 100% aluminized steel for longer service life compared to low-carbon steel, Walker SoundFX direct-fit mufflers deliver quality appearance and favorable acoustics while mechanical interior joints and spun-locked heads provide durability.

Features and Benefits:

  • BUILT TO LAST -- Internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion while spun-locked heads and OE-style spot welds provide stability and longer service life
  • EASY TO INSTALL -- Direct-fit bolt-on replacement solution with OE-style hangers, brackets and pipe routings for easy installation that doesn't require specialized fabrication and/or welding
  • FACTORY SOUND -- Louvered tubes help reduce radiated noise for factory-style sound quality compared to straight perforated tubes
  • GET MORE MILES FROM YOUR MUFFLER -- Designed and tested to extend muffler life
  • RESISTS CORROSION -- Aluminized steel construction and internal drainage system helps reduce corrosion
