Enhanced Performance 🚗 Walker Quiet-Flow 21054 Exhaust Muffler Review

Lasted less than a year before falling apart. I welded it on to fix it and a few months later it snapped elsewhere. Contacted about their warranty with photos and proof of purchase - ZERO RESPONSE. Don't waste money.

Purchased to replace Magnaflow Fx on my 5.3 Sierra. It got loud and growled. This rollator got longer and was definitely quiet for a while until it broke, now it's a nice quiet rumble but most importantly no more rumble when driving on the freeway. I run a 3 inch hose from the cat's back, no resonator.

Very happy with the muffler. I rebuilt my 1989 K5 Jimmy's exhaust with a 5 x 8 x 24" straight through muffler and expected it to be quiet with a catalytic converter in front. It buzzed at freeway speeds and had more volume than I expected from my daily drive. Walker solved all these problems, nice smooth sound on the outside and no rumble on the inside.

Ordered this for my work truck to reduce its noise a bit. I had a FlowMaster Super 44 and as you know it's a pretty loud muffler. I opened the box and to my surprise it was a DynoMax 17233 Ultra Flo muffler. Paid $52 and got a silencer for $115! I installed it anyway and it's definitely quieter than the FlowMaster (big surprise haha). A little hum still, but tolerable. Good deep rumble, smoothes out well on track. Very happy with it.

Bought January 31st, installed next week and ALREADY rattling inside. Almost as if one of the inner plates is rattling at idle. I knew they were cheaper mufflers but figured I would get at least 2 months benefit from them. I would definitely pass, but what can I say, the next one won't fail so quickly. I wish I could just get my money back and invest in buying a Borla or a Gibson. The direct Magnaflow was too loud. That's why I got it.

Installed on a 2000 Silverado. Cut the stock muffler flush with the body. The pipe was 2 3/4" with a 2 3/4" coupler cut in half as a bushing to fit this 3" muffler into the stock pipe. Fits stock pipes perfectly. First start I was off disappointed by the silence but each time it got softer After about 100km the sound is superb Not loud and youthful like the Flowmaster, just soft tones in the background Quiet enough to talk and hear the whirring of the engine Me couldn't be happier with this…

Best product I've used on my 2015 Nissan Titan. I've had all different exhaust systems on my truck from Borla to Flowmaster Flow FX, fuel economy went down with all the other mufflers. I went from 350 per tank to 420 per tank which is a huge improvement. Now I'm enjoying my truck again, there's no more hum in the cab, it's quiet and has better fuel economy per gallon. I made a 2.5" pipe after the cats into a 2.5" and a 3" Y pipe and a 3" exhaust and the standard air intake is fugitive cold air…

Every time I repaired the exhaust system, my Nissan Titan seemed to get louder. First cracked exhaust manifolds, how many. I was going to leave the truck for a while and didn't want them cracking again so I used long JBA pipe elbows. Then I had to do B-pipes and after that the rest of the exhaust. Louder and louder every time. I already had a resonator, but the booth was too loud. Not the case after installing this Walker SS silencer. It was 6 inches longer than my muffler but slightly lighter.
