Description of Walker 21910 Quiet Flow Stainless Muffler
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. 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. 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. 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. DESIGN VALIDATED -- Acoustic and flow tested for quality OE-style sound you can count on.
