Product Information

Description:

UNIVERSAL TRU-FIT MUFFLER

Featuring 100% aluminized steel for longer service life compared to low-carbon steel, Walker SoundFX universal 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
  • FACTORY SOUND -- Louvered tubes help reduce radiated noise for factory-style sound quality compared to straight perforated tubes
  • FLEXIBLE SOLUTION -- Customizable design features expandable bushings for easy fitment and may require specialized fabrication and/or welding for installation
  • 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
