Product Information

Description:

QUIET-FLOW3 MUFFLER

The only broad-market muffler with 100% stainless-steel construction, Walker Quiet-Flow SS mufflers feature precision fit, superior flow and OE-style sound. Quiet-Flow SS mufflers are available for most domestic and import vehicles.

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
  • BUY WITH CONFIDENCE -- Comes with Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound Guarantee. Visit Walkerexhaust.com for details.
  • CORROSION RESISTANT STAINLESS STEEL -- The only broad-market muffler with 100% stainless-steel construction that delivers longer life versus aluminized mufflers while an internal drainage system reduces moisture collection
  • DESIGN VALIDATED -- Acoustic and flow tested for quality OE-style sound you can count on
  • EASY TO INSTALL -- Direct-fit bolt-on replacement solution with OE-style hangers, brackets and pipe routings for easy installation and doesn't require specialized fabrication and/or welding
  • PREMIUM ACOUSTIC CONTROL -- OE-style louvered tubes lower noise levels while OE-style domed heads help reduce radiated noise for premium factory-style sound quality compared to straight perforated tubes
