How to soundproof your BRZ - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

One thing that helped a bit for me was installing some damplifier pro under the insulation piece on the hood.

I wonder if this material will reduce drone or aftermarket exhaust sound at a certain amount. Anyone?

I put it in the spare tire well, trunk floor, and under the foam in the trunk and it made a moderate difference.

I agree with John. I installed CCF+MLV in my trunk wheel well and sides of trunk. My aftermarket is almost as quiet as stock (still sounds a lot better though).

Sure, but its in pieces. I recommend using solid pieces instead.

If you are interested, just PM me.

Finished everything but the front floor area.

MLV everywhere but doors, roof, and front floor area.

CLD covering probably 80% of the car at this point, not on the roof or front floor.

Thinsulate stuffed in every possible crevice in the quarter panels, under back seats/floor, and a few layers in the doors.

Doors really shut with a solid thunk now, even better than with just CLD.

My phone said the car was around 88dB before I ever got started if I recall properly, now it's saying 74-75dB. On dry pavement at 65mph. Rough roads go up to 77-78. My wife's 2013 Mustang is 79-80dB on smooth roads and it's a pretty darn quite car.

I must say, other than one stupid rattle I can't locate, I am finally pleased with the interior volume now!

Surprised no one has done the roof yet. I had an acorn bounce off my roof and I thought someone had bounced a billiard ball off it. There is nothing on the underside of the roof.

Unless it's raining/hailing/sky falling, you don't get anything more than some minor wind noise from it. I can't hear any discernible sound from above me unless I'm in a tunnel.

I covered my roof with Raammat. Makes rain sound like someone is slapping my roof lightly with their fingers.
