Description of Walker 21047 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.
The Walker exhaust system has greatly improved my vehicle's performance. My analysis of this product showed that it enhances my automotive's engine sound, as well as increasing its horsepower. I highly recommend the Quiet Flow Stainless Muffler. The only con is that it can be a touch pricey, but it is definitely worth the investment.
One year installed and still in the same condition. Great sound, not quiet but with a slight rumble on this four cylinder engine. You can only hear it from outside, but not in the car.
I bought one of these 3 years ago when they first came out. After 2 years, rust began to appear on the muffler body at the connection with the end caps. After 3 years it looks like the muffler will rust next year. Obviously it wasn't a fully stainless muffler. A lifetime warranty doesn't make up for the pain of a muffler replacement, and Walker's "SS" label on this product is clearly misleading.
