There are insulation kits you can install that will quiet the car down. Check with some of the forum vendors for pricing.

If its tire noise, when you replace the tires look for quite ones. There is a lot of info on this forum about tires and the pros and cons of each. Non run flat tires will be less noisy if you can get over the mental hurdle and go without run flats.

Nonetheless, I find that my Z06 to be pretty quiet all things considered. A cheap and easy step is to add a cargo mat. Certainly not a fix-all, but helps. More progressive steps would be to add sound dampening material, non-run flat tires, etc.

Yep, the wider tires and lack of much noise insulation make the Z06 as my 2017 Grand Sport, loud! Lots of Threads on folks who have added noise insulation. Frankly at best, with quite a bit of effort like removing the seats, covering the aluminum on the back of the seats and aluminum driveshaft tunnel, also putting quality noise insulation on the rear wheel wells and rear deck, the results are modest! You should search for yourself. See pic below of areas needing to be insulated. Some have used two or three different materials layers.
My method is much simpler! I have my sound system playing over 1000 songs in shuffle mode as soon as I start the car. It's never off! I have my phone set so it does not ring when I am driving. Spend my time looking out for distracted drivers (not being one) and having fun driving. Works for me and has since I got my September 2013 built C7 Z51 and now my Grand Sport.
It's not easy to insulate the interior and many have said at best it's a small help!

Crazy Dan sells an amazing sound insulation kit for the C7 and after I installed mine I can say it's so much quieter in my car and the car feels a thousand times more solid. I got the C7 Double Extreme Kit and without a doubt its the favorite mod I've ever done on any of my Corvettes. If you like to hear the sound of the engine and exhaust you still can and its so much clearer with so much Road Noise eliminated.
