Description of Walker 21565 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.
Based on our own experience, this muffler did not live up to our expectations. While it did produce a slightly quieter exhaust note, the performance gains were negligible at best. On the downside we found the installation process to be excessively difficult and time-consuming .Overall, we cannot recommend this muffler for anyone seeking significant performance improvements in their exhaust system..
Pros
Quieter than most mufflers.
Cons
Not as durable as other stainless mufflers on the market.
Product numbers match but sizes were different. The one I received was 16 inches long, not 23. The product also said it had a hanger. no hanger included. I'll go back and try to find a new one that fits. I forgot to mention that it was also dented and not packaged very well.
