Best deep muffler for 5.7

[Trio]

Do you have a video? And which specific magnaflow?

You need to one with right inlets / outlets for your specific application, but this is the most recent one (probably for the '96 Tahoe).

Sorry, no video clips.

Do you have a video of your 350 with the dynomaxes?

Unfortunately I do not.

My vote is for Black widow neighbor hater. I had one on my 98 5.7 and it sounded great, I had stock cats with stock pipes, with no drone and a little louder than a flowmaster super 10.

I want to try one of those would also like to try https://blackwidowexhaust.com/mufflers/Angry-Housewife-–-$104-00-$119-00-U-S-c55605001 https://blackwidowexhaust.com/mufflers/Race-Venom-–-$129-00-$148-00-U-S-c17838009 these are new I think they are made for diesel but would most likely sound great with gas as well https://blackwidowexhaust.com/mufflers/The-Big-D-–-$189-U-S-c171375050 any one know what the difference is between the neighborhater and the widowmaker 10

I ran the Dynomax Ultra flow welded on my first big block'd Malibu. 550-ish horse, 2' primaries, X-pipe and bout a foot of dumps off the mufflers, just in front of the mufflers. it was LOUD, but with the X it had a cool sound to it. Always wanted to run it again. Buddy put same mufflers on his truck, (97 ECSB 454 all stock) and was quiet. I don't remember much, it was 20 years ago lol. So many choices, and sound clips on a computer suck lol.

Another vote for Magnaflow style. Flowmaster's FX mufflers are good and pretty cheap. The Cherry Bomb Salute is a good, cheaper option too. On my truck with stock cats the Salute sounded really nice, had a super deep idle and was really pretty quiet. Now that I donated the cats to a better cause, I've got FlowFX singles running into the Salute and it's got a nice deep idle and it's got quite a bit more bark to it now, sort of a tame glasspack sound when you stand on it. A little different on a big block, but it'd still make a 350 sound pretty mean.

Yet another vote for Magnaflow. I recently installed their complete exhaust system (manifolds back) and started the new engine on my truck for the first time. It sounded good. I'll try posting a video in my build thread this weekend.

That would be great, and a parts # or name?

sounds like magnaflow is the winner here with dynomax as number 2
