I watched this video, read the comments, even the not nice ones, ordered this stuff and did my c6, and it works. I also drive as a daily driver. It cut out a lot of noise. Thank you.
On such a car, which I also owned and experimented with, the biggest difference in road noise reduction comes from: 1. Adding additional 3M rubber strip insulation to 2 doors, hatch and hood, to drastically reduce ingress of exterior noise. 2. Spraying multiple layers of rubberized undersealant to entire undercarriage + 4 wheel fender areas. 3. Underhood noise insulation.
Nice work! Although I would have put two layers of Dynamat on those large flat sections..another trick is to put mass loaded vinyl on top of your Dynaliner
great review; a decibel meter doesn't lie, though neither do ears. 6-10dba is great, I dig that. The thing I heard was, as you mentioned, the tonal quality change of the exhaust; it seems one would get fatigued very quickly. This helps illustrate why so many people in the forums are having less than stellar luck getting the "tomb-like" sound. Sound damping & isolation, or lack thereof is design choice & one best applied in house. Why car companies don't consider the health & wellbeing of consumers, in this respect, is beyond me. I'm looking at you #Honda
Thanks for the excellent dB test comparison. I was shocked at -10dB!! However pleased for you. Imagine if you did every surface you could (I know that is A LOT of time spent), doing doors, bonnet, wheel wells...under car spraying if you are super keen and roof. Love your vette by the way, not a lot of these in Australia. The exhaust sounds "Gruffer", if there is such a word. 👍
Wow dude! You went all in very impressive. I’ve only done this once before with my last car it was hearty amount of time . I’m currently starting it again on my newer one lol. Great video!
Hi guy - Good video. Another big noise maker on many Corvettes is their run-flat tires. They also cost twice the price of normal tires and are 25% heavier. Replace those and consider a not-so-loud exhaust system to further quiet down the beast.
Nice video........glad to see someone that appreciates the a quiet interior even while driving a performance car...........you did awesome so far........the doors would bring it home.........and yeah you kinda do look like Matt damon
Excellent, excellent review - looks like you live near me, I recognize those road signs - anyway, doing the same to my 2021 Mustang GT - full coverage - you’re correct - it’s a big job - but absolutely makes a giant difference
Dynamat works. I've used it in every single car I've owned since 2004. It will filter out a lot of the road noises, especially the higher pitch sounds. However it's not a cure all product. Most of the road noise sounds actually come from your windows. One of my biggest complaints when I owned a 2015 Dodge Charger was the heat from transmission. Tearing down the interior I noticed that dodge put some effort into sound deadening already with thick carpet and specific spots with a cheaper version of sound deadening stickers.. However, It just wasn't enough. I did a cover all and it cut down my db down about 8-9 decibels . I would say a significant impact overall. Ceramic tint can also help with road noise and heat.
The day I traded in the charger the sales guy was impressed. He noticed a difference right away and asked if I had done something to the car because he drives chargers all day long and mine was much quieter than normal. I told him I used dynamat in the interior. (I installed it myself) and had a local install 400$ ceramic tint. I ended up getting 17k for the trade vs the original offer of 15k. Not sure what they sold it for because I don't live in that state anymore. But that 900$ investment helped secure me some peace of mind. I drive an Acura TL now that I paid cash for but haven't installed any dynamat yet.
Ceramic tint reduces noise? Haven't heard of that. I have a 2018 charger I'm about to get ceramic tinted, back when my wife drove it she skipped appointments to get it done, now the paneling is coming unglued bad, especially this year. I'm about to get three vehicles ceramic tinted, including my 2002 Chevy Tahoe that I'm putting a quality system in that's been fully rebuilt mechanically and it's getting sound treated. It's lifted and has load tire noise.
Oh and there's a reason why luxury cars have thicker glass. Cheaper the vehicle, thinner the glass. Almost wonder if one could put strips of deadener on it to take some sound out.
Omg this is the right video and the video I was looking for. can't tell how much I really needed to hear the difference the way u showed in this video was really what I was looking for in youtube thank you so much u deserve a 👍Honestly .
I appreciate this video a lot. Its taught that if were as willing and able as muddytaco to make a video, Id do the knock test from the other side of the panel to give a better audible description of noise transfer.
High way bunch mark it all, 86-88 to 76-78 = 10 dB diff It was 10dB difference, which is impersetive. 3dB reduction mean half the power delivered to the microphone sensor. So, 10 dB means more than 9 dB which is 3*3dB. Therefore a factor of 2^3=8. So, the noise reduction now is divided by 8. That is the noise now is 1/8th of the noise before the insulation.
@@AGCampagna I made it to the length I wanted. Just a pipe with a cap welded onto it going out of a 2-1 magnaflow muffler, I went for a low drone cancel so it ended up being 54". lol
Butyl based deadeners are better for bass because they add weight to panels reducing flex and rattle. What you really need is closed cell foam with mass loaded vinyl on top, it weighs almost nothing but its thick so it blocks out a lot ofsound. I use all 3 in my car .
I would have liked to see a sound comparison with you tapping from the outside of the vehicle in order to see the outside sound penetration differences between each layer. Obviously it will tap softer with a softer material on top of the Dynamat butyl layer, but what about from outside with and without the Dynaliner?
CLD (constraint layer dampers like Dynamat, Damplifier, etc) really only needs partial coverage (25%) to deaden all the metal/panels. CCF (closed cell foam like DynaLiner, Overkill, etc) is for stopping rattles of trim that vibrates. MLV (mass loaded vinyl like Dynapad, Luxury Liner, etc) is for the floor from the firewall/footwell on back and it will make the vehicle much quieter. Although you got results of lower noise, you may have went about it with the wrong product as far as Dynamat goes. That's a whole lot of unnecessary weight and $$$. MLV is heavy as well, but less Dynamat plus MLV might be a wash as far as weight and $$$ goes but it should provide much better results. All the companies that make these products (CLD, CCF, MLV) for sound control detail all the uses for this stuff on their websites. The except may be Dynamat which appears to push the 'more is better' concept for their CLD. See this video for a better explanation... th-cam.com/video/TQuR3x8Fd0I/w-d-xo.html
Jody V - i thought dynadeck was mass loaded vinyl? How many layers / how thick can you make your floor? im working on a ford diesel van right now. i have 2 layers of dynamat extreme. i have either 1/4 inch dynaliner or 1/2 inch dynaliner to put down. i would like to add 1/2 inch dynapad to this. So im looking at either 1 inch or 1 1/4 inch of layers under my carpet.
Check out Second Skin's website for the install steps. Doesn't matter which manufacturer of CLD/CCF/MLV you buy the basic install steps are the same. Good luck. store.secondskinaudio.com/install-steps/
Good stuff just I wouldn't pay big bucks for big name brands. I did my mistake long time ago and bought dynamat but if you get farther into the sound system you can actually find this deadener called vibraflex 190 mil. Your ride will get heavier by adding this so I wouldn't suggest doing that in a fast car. Also soundskin and second skin products are much affordable then dynamat and they take you into a different game zone that you will never look back into dynamat.
Did you only do the floor pan and trunk? I wonder how much quieter it would be if you also did the doors, roof, and front firewall. I’d like to install a straight cut gearbox in my car someday and I don’t want to hear it until I roll the windows down
I think that the noise would be a lot different with the knocking coming from the underside. Mini the the material you're knocking on and you're listening on the same side. With the knocking or noise coming from the other side then it has to pass through the material. But that's not easy to test I understand
Have you thought about doing your doors? Ive learned a lot after watching the Car Audio Fabrication channel (check out his door video) and think your un-dampened doors are the reason why your car doesn't sound better then a luxury car which is a shame after spending all that effort. Maybe do the firewall and roof as well because that is the only thing left without deadening.
Aren't you afraid of condensation driven rust? no matter how well you stick the sound deadner, there will always be mini air bubbles between it and the body panels... any experience?
More than half your noise is going to be coming from the firewall and on all vehicles it's nearly impossible but the best application is to get that Dynamite all the way up to the bottom of the front windshield. And that's pretty much impossible. Also if your center console continues to be hot pulled off flip over spray foam the bottom of it
For such a noisy high performance car, the cabin’s firewall is the most critical area. But its mostly not done. And on such noisy cars, Dynaliner is a waste of time, as its totally useless against the low freq booming droning noise. Your Dynamat Extreme or any equivalent shd hv been topped with the same company’s excellent Dynapad. That will make a significant difference
Surely no more than the equivalent of a few bags of groceries. This amount of material could be carried by a single person, and it's distributed over a large space so it shouldn't affect performance
You should just trade it in for a Lexus ES350!! Why would you add all that weight to a sports car? I'm confused by this "improvement". I daily drive my sports car too and would take the sound insulation out if it were not such a PITA. To each his own I suppose.
Dynamat is a great product but kills the performance of the car because of weight. Helps a LOT with the drone of an aftermarket exhaust on long highway trips.
Knock test and dynaliner does absolutely nothing. The liner isn't a resonance reducer, it is a noise (frequency) blocker. Reducing panel resonance is good. Blocking unwanted frequencies is good. Personally, he should have used half as much of the deadener and a lot more of the liner. He didn't mention if he did the roof... "A" for effort.
I watched this video, read the comments, even the not nice ones, ordered this stuff and did my c6, and it works. I also drive as a daily driver. It cut out a lot of noise. Thank you.
Most people might not realize, but 6 decibels is a huge improvement. I’ve been working with deadening products for 30 years and do a lot of semi’s.
Almost 50% less loudness
This was a great comparison video. Thank you

AWESOME ‼️‼️‼️
Very good comparison!! I love it! So do you think it worth $$? Will you do it on your future cars?
Awesome vid thanks bro
Big difference, I did dynamat x 2 but still need dynaliner x
HOW MUCH ADDITIONAL WEIGHT HAVE YOU ADDED TO YOUR....LIGHT WEIGHT CORVETTE?
Your mom's earring looks fabulous. And that 1987 goatee makes you look sooo tough.
Thanks for the comparisons it seems well worth doing it, was your hand brake on while you were driving?
Good video.
Hopefully you won’t get any interior rattles after you took the whole thing apart.
If you want quiter you need a layer of mass loaded vinyl onto with a layer of closed cell foam. Dynamat xtreme isn't for sound proofing.
Big question now is how much slower is it with all the added weight?
Do you know about the Weight difference? Before and after?
Cinco Ranch Blvd?! Going to the Alamo Draft House?!
That had to have made a huge difference in noise levels surely.
Is the dynaliner an option? What is the difference between just the Dynamat and Dynaliner?
how did the heat block affect?
Is anyone going to answer the darn door?

Rust on a fiberglass/plastic composite car ? There's no metal body panels in a Corvette.
@@NRGZ28 infact I'm not referring to body panels but to the bottom metal panels you've coated with dynamat 1:20
Also if you wanted to reduce engine noise on your vette probably should get hood liner and rubberize your wheel arches
Sound proofing the doors would make a big difference..and the hatch lid
Definitely need a metal roller to do it faster.
Nice man.. while your in there u might want to replace those crappy factory speaker
Knock knock........
Who’s there
The ride quiet like a Benz or Lexus now?
More than half your noise is going to be coming from the firewall and on all vehicles it's nearly impossible but the best application is to get that Dynamite all the way up to the bottom of the front windshield.

Pulling away in 2nd I was waiting for. Cop sirens stock and I warning 70 dB. Cop sirens with Dynamat. Ticket 60 dB. Etc. Lol
How much did all of that cost ya?
You have a magic hand, can do it by yourself. That’s save a lot of money.
I went to store cost very expensive.
How much?
gotta do the insides of the wheel wells
Hey man, how much weight it add?
Surely no more than the equivalent of a few bags of groceries. This amount of material could be carried by a single person, and it's distributed over a large space so it shouldn't affect performance
Supposed to knock on the out side my dude
is dynamat made of rubber?
You just added about 3000 lbs to your light weight!
Add the dampening and loose the spare tire lol
How much of it did u buy
