Features & Benefits

Warranty

NAPA® Quiet-Flow® SS mufflers feature 100% stainless steel construction for durability and corrosion resistance with a direct-fit, bolt-on design that includes hangers, brackets and pipe routings for easy installation.


  • CORROSION RESISTANT -- Features 100% stainless-steel construction paired with an internal drainage system to reduce moisture collection and rust-out 
  • 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 
  • DUARBLE -- 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 long service life 
  • FACTORY SOUND -- Unique internal tube design lowers noise levels while domed heads help reduce radiated noise for premium factory-style sound quality compared to straight perforated tubes 
  • BUY WITH CONFIDENCE -- Comes with NAPA’s limited lifetime warranty
