🚗 Enhance Your Driving Experience with Walker Exhaust Quiet-Flow 21356 Exhaust Muffler Review

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.

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.

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.

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.

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

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
