Description of πŸš— Enhance Your Driving Experience with Walker Exhaust Quiet-Flow 21356 Exhaust 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.

Easy to assemble

Muffler easy to assemble, nice and quiet. I have used Walker exhaust parts for a long time and have always found them to be of good quality.

Pros
  • Excellent construction
Cons
  • Not as thick as other options

Revainrating 3 out of 5

Unsealed but accessible

Welds were not sealed, used puddle of exhaust to seal properly. A cheap muffler that lasts 3-4 or even 5 years but can be easily replaced with 04 Silverado 4.3 v6.

Pros
  • Easy to read control panel
Cons
  • Reliability

good replacement muffler

Replaced a terribly noisy double pane on a recently purchased used truck. It's a lot quieter, just a small hum that makes it clear it's a V8 engine. I doubt "stainless steel" means it won't rust after all, you can attach magnets to it.

Pros
  • 1 year trial
Cons
  • Questionable purchase for seniors

Perfect fit just check the part numbers

I bought the components from r the cat back and they fit perfectly. Note: Part numbers can be found on the Walker website. The numbers on here were wrong for 1 of the 3 components, that saved me from replacing them.

Pros
  • Great fit for me
Cons
  • Vulgarity

Is this stainless steel.

The OEM muffler for the 2003 Silverado is a one-piece welded CAT rear system and costs about $800-$1100. The aftermarket systems were bare steel and didn't last long. The only stainless steel I could find after the muffler was the Walker. My front pipe and exhaust are also stainless steel but were in good condition. I carefully cut out the muffler, used a heavy duty pipe expander on the exhaust pipe inlet, temporarily reassembled the system, took my time and marked the inlet and outlet, removed

Pros
  • High marks for support and durability from testers
Cons
  • I won't say anything

TO UPDATE! Pretty expensive for a silencer. To update!

I was under the impression it would be as quiet as a standard muffler, many reviews said it was that quiet but I think they had a muffler that was too long and I forgot how quiet the native is muffler was. It's not LOUD, but it definitely rumbles a bit, and the stock muffler was a lot quieter. I figured for the money I spent I would get a muffler that was as quiet as stock. The inlet slipped over the intermediate pipe and could get pinched, but the outlet was almost the same OD as the outlet so

Pros
  • Great for a small home
Cons
  • Has issues
