Works fine! There hasn't been any sets for a Vert for some time (and probably wont), so I bought the one for the coupe and simply used a utility knife to trim the trunk mat to fit. This gave me an extra pad that if I wanted to, could use to almost double-up the trunk (but would limit carrying capacity).
The two seat pads just get placed behind the seats.
Don't expect some sort of "hushed" silence... but you should be able to discern a deadening of sounds from the exhaust (if aftermarket -- the OEM on my 07 was really quiet; since changed to something with more character...) and the pads behind the seats help deaden the sounds from rear wheel wells.

I tried the Block-it mat and also the pads behind the seat. Couldn't tell any audible difference so I returned it. The best way to cut down "some" of the noise from the cargo area is to apply one or two layers of a good quality sound deadener material like Dynamat or Damplifier, or many others. You should also add a final, thicker "mass loaded" layer like Damplifier Pro or similar. Check out this website for good products, theory and install tips. http://www.raamaudio.com
With a stock exhaust, the interior of the cars are very quiet, but when you start adding axle back exhausts, it starts getting louder and louder.
I did a complete cargo area deadening project but the best sound improvement I made to my base model was to upgrade the stock exhaust to an NPP exhaust and add an NPP in a box kit. Whisper quiet or lions roar at the push of a button.

Yes, many have purchased this product and if you do a search just on this forum alone, you will find an overwhelming amount of positive responses.
However if your looking for Cadillac quiet, this is not for you.
It absolutely works on taking the edge off tire/road noise and over the top exhausts. Plenty of data and testimonials from members for the C6 available.
It only takes approx 1-2 minutes to install (just toss it in.) Simply take the Blockit out for race events if you want. Your not permanently gluing a ton of weight to your car like other products.
But don't take our word for it, here are some positive posts I grabbed from the forum.
Its good that there's a bunch. Sorry that there is a bunch
Hey, just a quick shout out for a good product. I installed this in my '16 Z-06 and I'm very pleased with the product quality and sound. I still clearly hear the lovely rap of the exhaust, but not a lot of the tire noise on our nasty worn roads. Very pleased with this product.
I installed the 3 piece system and finally got a chance to do a test drive this evening. I was very pleasantly surprised how well it worked as the improvement was immediately noticeable. The noise level inside the cabin was reduced and I had to lower the radio volume since it was so much easier to hear. I can still hear the nice sound of the engine & exhaust, but without the annoying road noises. Very pleased with this purchase.
I installed the Blockit sound insulation mat and the behind the seat panels this weekend and I am very impressed. The mat just goes in the hatch area and the fit is excellent. I installed the two panels that go behind the seats behind the carpet. The carpet in that area is not tacked down so it is easy to do.
The mat looks very polished in the rear cargo area so I don't think that I will add an aftermarket cargo mat on top of it.
While commuting to work this morning on the freeway I really did notice a difference. I did not have to crank the radio way up and the voices and music were much clearer.
If you are looking for a real easy sound insulation solution I would recommend this product.

While at Carlisle last week, I came across a product called Block It at the TKO Performance display tent. We all know how many of our roads are not in the best condition and how load road noise can be. Block It is a multi layer foam pad which goes under the rear cargo mat. There are two additional pads which go behind the seats.
All I can say is the drive back to Florida was significantly better with Block It installed. It's not Cadillac quite, but the road noise it much less at highway speeds. Even at lower speeds while running exhaust in track mode, the exhaust sound was clearer and not as cluttered as before.

I got mine yesterday and installed it last night.
First drive to work this morning and I can tell you it makes a big difference. Those that say it doesn't must have some really frickn' loud exhausts.
It took the resonance away that the road puts through the rear hatch area (hatch floor, plastic) and the road noise from the tires is probably cut in half.
There's also a noticeable "quietness" inside the rear now that I never had before. I always had that "white noise" behind my head from all the noises coming from the rear hatch area. Now it sounds like the entire car is quieter.
It made such a difference I am no longer worried about putting dynamat or peel and seal in my car. I will however still do the peel and seal on the floor boards under the car because now that the rear is so much quiter I hear road noise from under the car... lol.
Overall, it's a great buy and I'm glad I bought mine!!

To start with, I am not a vender and do not sell these things, but WOW! What a difference.
I have an 05 vert with borla stingers and love the sound. But on the interstate and highway speeds, the car is just kind of loud. Not just from the exhaust, but from road noise. So I bought the new "blockit' insolation kit sold here on the forum. Not the kind that requires you to remove the carpet or anything. Just put two pads behind the seats and one pad in you truck, or cargo area for a coupe. I drove my car at 70+ MPH for a good ways last night and WOW!!! Much smoother and peacefull sound. The stereo sounded better and the car just seems so much quieter in the cab area. I have had a C6 coupe and now have a C6 vert, and I promise you, this thing works! Just wanted to shout out a nice mod.

Just wanted to shout out a nice mod.I was at Carlisle and the Blockit was sold out, so I bought the demo kit that was inside the Corvette parked under the TKO tent. In my opinion, it was worth it because it works. My C6 is very loud, as it is cammed, etc., with headers & NPP. It has an annoying low rpm drone. With muffler flaps open it is unbearable for cruising below 1,950 rpms. Even with flaps closed, the drone was very annoying below 1,950. Most of my cruising is between 1,700 and 1,950 rpms in 6th gear with 4.10 gears. With the blockit installed, the drone is gone at these rpms with flaps closed. Not just reduced, but gone. Below 1,700 drone is reduced to a bearable level.
With muffler flaps open the drone is reduced with the kit, but still louder than my comfort level. But it's a moot point now.

Having had Blockit in my Z06 - I thought it did a great job reducing noise so I added it to the C7 - Z51.
It arrived packaged well. Easy install with a precise fit. I was able to use the rings and shade. I found it able to make a nice noise reduction on all surfaces around Little Rock including interstate and different road surfaces including concrete and asphalt.
I'm very happy with the product!

…..On rough pavement we can actually have a conversation without yelling. Stereo sounds great but we can still hear and feel that awesome exhaust!
Thanks TKO
Thanks TKO
Installed on my C7 Z06. TRANSFORMATIONAL! The reduction in tire noise is astonishing. Being an engineer I had planned to use my laboratory dB meter to measure noise levels with and without the TKO Blockit kit. As it turns out there is no need to do so because the noise reduction is truly dramatic. This kit is a "must have" for all but deaf C7 owners. I had a '14 Z51 which had hellacious tire noise. I was exhausted after driving it for 3-4 hours. The '15 Z06 was significantly quieter and rides more smoothly....think Chevy vehicle engineers softened the suspension bushings. Seems to be well known that the '15 is a quieter car. Just can't believe how such a relatively inexpensive and easily installed kit can be so effective. I could now drive the car across country....yes, it's that good.
Well, I had a chance to test drive my car on some roads that previously had some serious tire noise due to the road conditions. For the ease of installation and simpleness of the product; I'm very pleased with the it. I was able to lower my radio volume from where it used to be, and hold conversations without raising my voice. In fact I am now aware of other noises that I hadn't previously heard.
So bottom line: I'd recommend(your hearing my vary) .
I can't say it's equal to the kits that require full interior dis-assembly since I didn't do that, but I definitely feel there is value in the product. If you are in Southern Calif and want to try in your car, come by and we'll throw it in and you can hear for yourself. Or just take my car for a test drive.

Received my set of sound deadeners yesterday and promptly installed them in about 10 minutes.
Started the car in my garage and could hardly hear the exhaust with the windows up. Backed it outside ( a lot of snow here now ) and tried the same thing, windows down ,windows up. I will not get to take the Z06 out until spring, but I can tell you that there is a substantial difference in the noise factor just sitting in the car and listening to it run.
Great product. Can't wait to do a more extensive test in the spring, but initially this seems to be a great product !!
Many thanks,
Dave

3pc set with aftermarket carpet on top in hatch works great. Almost too great for exhaust sound. 
Just got my Blockit mats today and did a roadtest on the concrete I16 around Savannah and a couple miles on local black top.
Super easy install - drop in and forget it. I have a coupe.
Big rear mat had the slits for rings.
Put my Stingray logo rear carpet on top of the mat and also put the mats behind the seats.
I can tell a difference in noise ; can hear the radio better and believe a long cruise will be far more pleasant.

I have the Blockit mats. My wife can hear like you wouldn't believe. She is the perfect test for these. She stated to me that there was a significant difference in sound reduction. That's good enough for me. I thought there was a difference too, but I didn't want to rule out wishful thinking on my part so I had her listen before and after.
I put it in my 2016 Z06 last week and the difference is very noticeable. Less tire noise, radio volume setting is lower now and much more enjoyable. As another poster noted the exhaust sound now stands out more; my Z06 exhaust is normally set to track mode.
I did notice the action of the Bose audio pilot (auto volume compensation) is much more noticeable now and I turned it off.

obviously super simple to put install, in a 10 min trip to the store... noticeably quieter. i have LTH, high flow cats, and factory npp. to me it sounded like i had the flaps closed.. maybe even more quiet than that.
…… is it worth the $230?? to me yeah, because i am lazy don't want to pull all the carpet out.... so with that being said, money well spent to me

I purchased the BLOCKIT "QUICK & QUIET" DROP IN NOISE DEADENING MATS AND THE BLOCKIT DEAD MATS 18 "X 32" - 5 SHEETS
Really reduced road noise without reducing the exhaust note. Now I don't need to turn the radio up so high.
Must have add-ons. Worth the $$.

I bought the set from Blockit. It seemed to cut the exhaust roar down about 1/3. Worth the $229 I paid.
Finally put the top up. Certainly can tell the difference. Car is a bit quieter, you still hear the roar at take off from dead stops and when u hit the gas. But when cruising it's a nice peaceful quiet. But even more important to me, my c5 is a daily driver and living in Fl it gets really hot. I've noticed that my trunk is a lot cooler. Every night when I leave work I put my laptop bag in the trunk and I think hope the heat doesn't kill this thing. Well since the block it install the trunk with the top up or down seems much cooler. Well worth the price of admission lol.
…..Another thing I did was add the Blockit sound deadening mats to the rear hatch area. These things actually work well to attenuate the wind and road noise so that the exhaust sound comes through. I am surprised how well they work for this and it was unexpected.

Received mine today; installed and drove; it really does make a difference; Thanks for making a great product; I personally wish Corvette would offer a "sound deadening" option as I would buy it even if it was somewhat costly!!! This works great and easy to install!!, Dwight Alexander
I dropped in a set of Block It sound mats (cargo area plus one behind each seat) in my C7 Stingray coupe.
Using the Decibel X Pro app, I measured 2 - 5 dB lower noise levels on varying roads at varying speeds, which was noticeable, but more importantly, the cargo pad cut down the reverberations from the drum head that is the cargo floor and reduced the noise spikes generated by road joints and seams... The 'Vette is now about as quiet as my '11 Mustang GT 5.0, my previous "touring" car...
The pads aren't cheap, and do add weight, but they attenuate much of the most annoying noise from the back of the car. IMO worth the money.

I received my Blockit kit last week and today I received it’s companion Lloyd’s cargo mat today. Everything fits and looks perfect. Best of all, I can really tell a noticeable improvement in road noise inside the cabin. I never measured the db’s before and after the install, but it certainly is quieter and more comfortable.
I’ll pile on...added this and the plush trunk mat from LLoyds and the road noise in rear (tire and exhaust) are much better. Even got rid of some of the boominess from the BOSE stock sub. I won’t be getting rid of mine before I sell the car.

I received my Block it this week and was able to test it pretty throughly today. My EB convertible has a Ford Performance tune which eliminates the fake engine noise which is great but it also removed the noise canceling feature which introduced quite a bit of road noise in the cabin when the top was up and windows closed.

I ran sixty miles today with the top up just to test it and was pleasantly surprised how effective the block it is. Road noise was significantly reduced and made the car very pleasant inside. Honestly I felt all along that the road noise was coming from the rear seat side panel area that houses the top mechanism.. Looks like I was wrong.
What really has surprised me is that the Block it has made a noticeable difference with the top down. I would never have expected this. Sometimes in heavy traffic the noise can leave me a bit frazzled after awhile. After fourty miles at freeway speeds top and windows down I didn’t have that noise fatigue I would normally have in heavy traffic. More time may be needed to test this for sure. Fit was near perfect. Only draw back might be that it’s fairly heavy. Maybe fifteen, twenty pounds?
I wasn’t expecting too much from this product but it has exceeded my expectations and I would buy it again.
I just finished testing the tko performance sound deadner kit.
The kit consists of a sound deadening mat and two rectangles of sound deadening material that are placed behind the seat backs. (For more info see www.tkoperformance.com )
First impressions:
The mat and seat back pieces are well made (the cut edges are very regular and even. The pieces are symmetrical ( I measured ) and look good. The fit of the mat in the cargo area of my c4 is excellent. The installation was very easy.
First test drive:
The first test drive can be summarized as: Amazing! I expected some improvement, but the I was amazed at how much. The exhaust resonance heard in the cockpit is very reduced and the tire/ pavement noise is also very reduced. I drove on several road surfaces including newly resurfaced, old pavement and concrete. The noise level in the cockpit was very reduced in every case. The high frequency noise on the concrete roadway was from the front tire area only.
A very good product and I can highly reccomend it.

I found it useful for keeping luggage and coolers a lot cooler but noise not as much. I heard they smell like tires brand new for a while. One can install an insulation kit for the same areas cheaper with better results and not much extra work. I just never got around to it on my C6.

Ordered/installed mine from TKO back in March of this year. I ordered the Blockit "Quick & Quiet" Mats PLUS DeadMats and noticed a difference particularly with road noise. I have NPP and mild to wild so I can get the cabin very quiet when I want. My wife noticed a difference too. I let the mats expand (comes rolled up in a box for shipping) and air out a couple of days in my basement and didn't notice any excessive smell. TKO was very responsive and helpful.

I noticed a remarkable reduction in noise with my trip yesterday down to our house by the beach... loaded with travel bags, my guitar in its case, and coolers (with beer), what a difference in sound, could really hear the music so much easier... maybe I'll drive like that all the time!
