Thers a big difference between having a VGT turbo and a fixed vane, I had a VGT in my 2012 RAM 2500, 5" TB straight pipe with the Flo Pro twister, the truck was quiet as can be, and now with the fixed vane and the same exhaust, it's louder, way louder, I had to add a muffler to quiet it down to make it sound better and still have the turbo whistle like a 5.9.
Props for keeping it tolerable and avoiding flatbiller dieselbro status. Don't get me wrong, I have a big block drag car that's stupid loud and I love it, but for daily driving, and especially diesels, it's so much nicer when they actually sound good without being obnoxious, especially at 6:30 AM when I'm your neighbor. It's a fine line sometimes. Yeah, I'm getting old.
Cruise at 50 didn't change by an audible decibel level to the human ear since the human hears only 2 db increments. A 10db increase will sound like twice the loud ... so the 4th gear pull 6db less muffled so it's a full 50% noise reduction to the human ear. The in cab idle drop of 8db is a 75% noise reduction . The 3 drop outsude at idle is a moderate drop the ear at 3db which only 2db is noticeable . I'm conflicted with putting on my twister I've had it sitting since I deleted . The only time I find it overly loud is full throttle and that's mostly because it sounds raspy not deep and throaty. The exhaust brake under heavy rpm also sounds squeaky. I got the small 12 inch main body resonator once I put it on if I don't like it I'm going to have to buy a new center pipe after cutting to fit.
I don’t regret putting mine on at all. At first the inner teenager came out and I miss the loud sound from 5” straight pipe. But now I’m glad because of neighbors/cops/family during long trips.
The CFM Flow Video that you are using for your information (at 4:53) are labeled 5" pipe and muffler. If you go to the FLOPRO video I believe the test was actually done with 4" pipe and muffler.
I just bought a 2018 ram 2500 cummins , previous owner has it straight piped and just went to get it inspected and they told me it is too loud...I was like......really... so now here i am researching mufflers to satisfy the inspection station.
@@Justthemow I got it inspected at a local place instead of valvoline. Texas doesn't care per se but because its valvoline they don't want to risk a federal fine.
So my area doesn’t have sound laws or emissions testing but I have a stock 2016 3500 dually and don’t want to light up my gauges like a Christmas tree. I noticed your didn’t have a CEL with the muffler. In your opinion would that be the way to go?
It is hard to hear the difference over video or certain situations. Overall it is a lot quitter, honestly a bit too quiet for my liking but not worth undoing all the work. Exhaust break is a world of difference and was the most significant change.
@@loganhill3853 i did research and they say its better to put it right after the downpipe instead of further down. So I am going to talk to some local shop guys about it
@@dozerboyd8784 It's hard doing it with a phone since that's not really calibrated. I wish I would have gotten a legit decibel reader. Peak it might be louder, it's hard to say for sure. Cruising is definitely quieter though.

The Blue Steel face was on point!

That’s good to know. I’m running 5” on the truck so it might not be exactly the same results as flopro test
Great video, awesome comparison data, We need more videos like this!
Thank you! More to come!
Efi live... adjust turbo min max tables it will be as quiet as a muffler...the vgt position is what quiets it down.
fuckin mint video man thanks for not dragging the video length out.
it's actually louder when pulling WITH the muffler? weird.

I dont have an issue with drone on the highway i just sit in 6th gear an it drops a lot. low gear or in 5th when pulling yea people lookin
What fucking communist state do you live in commiefornia Lamborghini and the like have horriblyloud obnoxious exhaust sounds.

@@Justthemow в России живу я))
What did you end up doing? I just did a second gen swap and curious what else I could do to get it quiet
Thanks for the review.
The video is hard show the difference but I’m happy with it at Idle and normal driving. Thanks you for the comment!
@@loganhill3853 I figured. Thanks for the reply. :)

This muffler is a solution if you’re deleted. I don’t think it would make a difference in stock exhaust
Twister muffler it’s better then regular muffler ?
Honestly i didnt hear a difference

@@cynicaltexan9639 keep us updated! Thanks
Killa sound on it
What length did u get
It is a Flo~Pro Twister Muffler 5"in x 5"Out - 18" - 12".
So the higher the dB the better?
Higher the dB the louder
South Carolina? What part?
I was in Sumter for about 6 years, moved to texas temporarily but plates are expensive here... i'll keep my palmetto plates for now...
@@loganhill3853 heard that. I grew up in Lancaster. Bout an hour and a half from Sumter. Passed through there a lot going to Santee
@Tyler Gaulden yes sir 6 years
With resonator the truck still strong don’t lose power?
It didn’t seem to lose power at all
fff drone 😵💫
Did you take off the Particulate filter also or is that still on the truck?
Dont ask those questions😂
@@randomchannel4886 definitely works for the epa
I'm confused? Did it get louder?
I would say 80% of the time it is quieter. Overall I'm very happy because it's quieter at idle and cruising.
According to his dB yes other then at idle....I'm so confused.....

@@loganhill3853 ya I'm not sure how accurate those meters are. It might be louder but only at some frequencies that actually make it seem quieter
@@dozerboyd8784 yeah I think that’s what it is. I got the muffler to quiet the truck down the majority of the time and it definitely worked!
