Default Any C7 owners use the "BlockI" sound deadener Mat

Perhaps you can help.

What is the thickness of the "BlockIt Mat" that goes into the rear cargo area?

Did you lay it on top of the carpet, or place the mat under the carpet?

Thanks in advance.

Mine is 3/4 inch thick I layed it on top of the carpet in the cargo area and placed another aftermarket corvette cargo mat on top of it. I also placed the additional mat behind the passenger and driver seat .
I also cut slits in the blockit mat for the cargo rings.

Here are a few C7 posts I pulled..

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.

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!

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.

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

i installed mich a/s tires which helped a lot but the block-it mats finished the job. Almost no road and tire noise. And i still have the deadmats to install if i want.

Does it diminish the sound of the exhaust too?

Also does it come with the slits for the hooks pre cut?

Mine had the slits already cut and yes, it will slightly diminish the exhaust sound. You can fix this by opening a window!

We're still happy with ours. Definitely takes the edge off tire noise/rumble on the highway.

It definitely made a big difference for me. It took all of a minute to put in my car and did have a noticeable effect on the sound. Great product.

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.

Nice and detailed. I know you mentioned exhaust noise in the beginning, but did you find the exhaust noise damped at all with the Block It Mats added?

That's one of my worries - that alongside cutting down the road noise (which I would desire), it will also cut down the exhaust roar (which I really don't want happening).

I found the exhaust note to be more audible. I don't think it got "louder", but rather there's less higher-frequency noise covering it up.

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.
