Has anyone used a Walker Quiet Flow 3 muffler?
Curious if anyone has used a Walker Quiet Flow 3 muffler, hopefully on a 3" exhaust like I'm considering lol. probably a long shot.
I have to quiet my exhaust down, can't take it anymore, and I'm probably not making my neighbors at my new place that happy either. A buddy of mine had a Walker 21054 on his LS1 and got rid of it because it was too quiet, which sounds right up my alley. I want a significant reduction in noise over my current 3" in/out Magnaflow XL. I put this muffler on there specifically to shut this exhaust up and it failed.

Yeah, I know what you mean. I had a Magnaflow cat back system hooked up in my old max, and it was super loud and annoying. It took me all of 7 days to get back under there and put on a Walker mid pipe and quiet flow muffler. Believe me, I have hate having to re-do jobs, and it was so worth it for the quiet sounds of the Walker. Up front I run Warpspeed Y pipe and high flo cat in both a max and i30, great combo! Walker is great value and lasted 3 years + still going! Warpspeed too!

The Walker 21182 SS OEM style muffler I installed last year is very quiet. Other good aspects is it being SS and it spits out emissioned water so it won't corrode away like my previous mufflers. The drain hole on the Walker 21182 and 18567 OEM style mufflers have a horizontal drain hole in the first chamber. My Bosal that rusted away from inside had a drain hole in the 3rd chamber vertically below the tip so emissioned water only drained when I raised the front end.

Just did an entire Walker system from the exhaust manifolds to the tip last month. I used their 21182 muffler. I know its not a 3" system like you are working with but as jholley said it has good design features and is factory quiet. The only piece of the Walker system that was junk was the little pipe section for the '97s where the downstream O2 sensor is fitted. The bung is 90 degrees off in orientation. Had to put a factory part on there to the tune $90 for a 8" chunk of pipe. The new p/n is now cast iron vs. mandrel bent pipe.

Well waiting on the verdict of what size is your resonator and whether you're running a cat ot not....Second of all what brand 3" catback are you running (Cattman, BRM, Custom, etc), what's it content (SS, Aluminized Steel, Titanium, etc)? How many miles do you have how the system since installed?

I'm running 2 walker sound effects mufflers, 22" shell length, and a 30" glass pack for a resonator. Sounds nice and quiet unless I really get on it. Even then its not what I would consider loud. I also have a high flow cat. If I had a stock cat it would sound "stock like". The cat added some noise.

I have a full Cattman exhaust...y-pipe ... 2.5 ... to quiet things down I swapped the axle back with a Walker Quiet Flow. I am very pleased with the sound, louder than stock but not obnoxious.

There's your problem!!!! Too small of a resonator!!!! I actually would recommend a you go with a Magnaflow rear muffler p/n :12588 or 12579 and a 6" round muffler p/n: 12649 (18" long) or the mammoth 12641 (30" long)...I use a 12649 on my Cattman 3" catback and you don't know it's equipped with a 3" exhaust nor headers...Good luck!

It is 18x9x4 approximately.
I was considering that monster 12641 the other day too. I may end up going with that and seeing how much that quiets it down and if it's still not quiet enough address the muffler, or maybe do both the 12641 and a muffler at the same time.
Other idea i was toying with is simply reducing diameter at the muffler down to stock exhaust size and putting a stock muffler on there. I don't care about the power loss, the car is plenty fast anyways and all i care about is getting the volume turned down at this point.

Magnaflow 12641 was delivered today, hopefully installing next week. Also Cmax determined my muffler is the Magnaflow 13259 since you were asking earlier (and prior to that was same setup with a Dynomax 17221 which even though the mufflers were totally different sounded basically identical.)

I found a 4th gen in the junkyard with a 17221 Walker(DynoMax) and installed on a friends 4th gen and it sounded really good! Yall have too removed the chassis strenghtening brace for good to run that 30" muffler!

installed the 30x6" magnaflow 12641 over the weekend and it is frickin AWESOME. we took before and after vids, and I took some sound level measurements too on startup. Sound volume, harshness, and just sound quality is so much improved. I no longer count my exhaust sound as something "embarrassing" about my car and the car is so much more enjoyable. I can actually start my car and drive out of my neighborhood without waking the dead, and i have fun driving the car in a spirited fashion again rather than just being embarrassed with how it sounds.
sitting in the driver's seat, first start of the morning with the windows up and door closed, before the resonator install the loud "bark" on initial startup measured 94.5db, after the resonator install it was 87.6db. the difference is huge.
will post the before and after vids soon.
