The Walker stainless steel Quiet-Flow Muffler has been developed to provide the top-grade performance you expect from one of the world's leading emissions control companies. This is the only broad market replacement muffler that resists rusting three times longer than premium aluminized mufflers. This part's internal design features bridge construction, durable internal partitions, strong interior spot welds, and special position of the inner shell and outer cover lockseams to improve the muffler's structural stability, strength, and make sure it will last much longer.

To allow OE-quality and factory-style acoustic performance, the muffler is constructed using louvered tube technology, CRF technology, and features three-tube design. Internal tubes are mechanically joined to the partition to allow free-floating expansion and contraction during temperature changes. This elaborate design eliminates the breaking of spot welds, subsequent part deformation, or loose part noise troubles. All stainless steel structure and perfected interior construction make the Quiet-Flow Muffler one of the most advanced, premium designs available today.

Much Better Than The OEM

Walker® 47800 - Quiet-Flow™ Stainless Steel Oval Aluminized Exhaust Muffler and Pipe Assembly

Really like the quality the quietness and the performance overall. Very happy and it was easy plug and Play. Of course it will take some effort to get rid of the older one.

Louder than OEM, Also Stop Putting Paper-Based Stickers on Exhaust Parts

Walker® 56124 - Quiet-Flow™ Stainless Steel Round Aluminized Exhaust Muffler and Pipe Assembly

When accelerating, it is noticeably louder than OEM part. FFS why must there be impossible to remove paper based stickers all over these exhaust parts which are meant to get hotter than a conventional oven? Spent half an hour diligently scraping them only to have the residue burn enough to make everything smell like smoke. Spend the extra 2 cents for a plastic based label and pass the price on to the consumer even. We're spending hundreds of dollars on these things, please respect our time enough to put a sticker that comes off the damn exhaust part within one eon of trying to take it off. Also, please include the bolts which fasten the tailpipe to the muffler in the Honda Element exhaust diagram.

Great Muffler

Walker® 50065 - Quiet-Flow™ Aluminized Steel Oval Exhaust Muffler and Pipe Assembly

I own a 2008 Jeep Wrangler Sahara with 3.8L engine. The Walker Quiet Flow muffler is a perfect fit. Easy to install and has a very nice tone.

Lasted Four Years

Walker® 55104 - Quiet-Flow™ Stainless Steel Oval Aluminized Exhaust Muffler and Pipe Assembly

I bought this muffler February of 2017. It was easy to install and sounded pretty quiet. Unfortunately the tailpipe corroded where it joins the muffler. It broke today (May 2021) and the muffler was scraping the road, hanging by the rear rubber hangers. I thought that it would last longer. I live in the Pacific Northwest. It's wet but there is no salt on the road.

Excellent

Walker® 54843 - Quiet-Flow™ Stainless Steel Round Bare Exhaust Muffler and Pipe Assembly

Purchased this muffler and had it installed at Monro Muffler. I was told that this muffler was of better quality than their stock muffler at less than 1/3 the price. I saved a great deal of money by buying my own muffler and having them put it on. Happy Happy Happy.

No Box?

Walker® - Replacement Exhaust Kit

Part is fine but not sure if it was dented when shipped or got dented on the way to us. But it wasn't in a box so it was dented. Got 2 parts both not in box and both dented.

Walker® 50085 - Quiet-Flow™ Stainless Steel Oval Bare Exhaust Muffler and Pipe Assembly

I put this on a 2008 Chevy Malibu with a 2.4L engine. It is a PERFECT replacement for the oem single in, single out muffler. You only need to change your lower valance from single to dual an easy job. It is of real good quality at a really good price. No modification is needed, just take off the oem muffler and replace it with this one. I can't say enough about the quality of this muffler. It is a Walker after all.
