sound deadning/insulating your car.

I was wondering if anyone out there actually used sound deadening material like dynomat to insulate the interior from exhaust noise? particularly the *unwanted* sounds such a drone ect.

*unwanted is subjective as some people I realize want the drone sound and even like it. I'm just wondering what those out there have done to deaden the drone sound in their car?

I used a product called B-Quiet Ultimate which is essentially the same thing as dynamat but significantly cheaper and I can definitely say that it worked. I put it in to enhance the sound of my stereo rather than to block out exhaust noise but it has certainly turned the volume down a bit. As far as drone is concerned, I don't have any with the Borlas so I can't help you there.

I will warn you in advance though: it is a PITA to install... Climbing into and out of the tiny trunk a thousand times was not my idea of fun, but maybe that's because I'm 6'5" haha

I installed Dynamat inside the doors, under the floor mat, back seat, and all around the trunk, and under the hood.

They work great!

In case you want to install them under the floor mat, be careful not to break your door sill plates. Most importantly, to follow the correct instructions to depower the air bags, before you remove the seats.

Did it for exhaust and made a huge difference. However like already said it is a pita climbing around putting it in.

I'm really anal about various noise and high decibel levels in the cabin but I've always felt that my V6 is as quiet as a lincoln.
