Sitting beside the car now .. They are fast and I had the GF pick me up for lunch and they had already finished the back when we got back. Had them take off every panel, behind the speakers, under the shifters everywhere. Even the doors. I hope you guys were right....

You might be referring to my thread, check out post #7 on the first page. BUT, I stuffed plastic bags using fiberglass house insulation into the 3 rear compartments, NOT the wheel wells. These compartments pick up and amplify both tire/road noise and exhaust noise because of their location.

Ok guys...so here are my thoughts after driving the car about 50-60 miles tonight after getting the following done at TPS today.
I mention the seats because they help the car feel completely "new" as well. So much more feel and control having nice race seats.
Anyhow the only way I can describe the car? More precise, more firm/rigid, more refined and definitely a nice change.
I could care less about the weight gain, the first two additions made a big difference in the feel of the car. The cabin noise was drastically reduced...there is still a good amount of tire/road noise and wind noise is there (hell, it's a Chevy sports car), but a definite and noticed improvement.
The car in general feels much more precise, poised and solid over bumps, rough roads, lane divider bumps, etc...the car just feels/sounds a bit more refined. Some less creaks/rattles for sure. Doors feel a tad more solid upon shutting, etc. The stock Bose stereo audio is more discernible at highway speeds.
I have a cabin/trunk sound divider coming as well, and I will likely try the foam that Oldvetter suggests in the rear as well. I can't wait to see what these also add (or remove
. Hoping that will help my stock stereo audio experience.
Anyhow, in closing. This is some money well spent. If I had the time, room and tools...I would have done the sound proofing myself. It's sure nice though to drive in and out with what feels like a reasonably more solid/refined car.
If any of you have yet to do the tunnel plate or sound proofing for your car, don't hesitate in my opinion. I like my car even more now.
If you're in the Bay Area, look up TPS in Campbell. Did a solid job. Mike is a solid dude to deal with. He'll get more of my money.
If you have any more ?'s, feel free.
Thanks all.
PS: As far as the decibel reading - Mike said I lost 10db's in the cabin sitting in it at idle. For whatever that's worth.
- New Tunnel Plate (insulated version)
- Complete sound proofing (see previously posted link in thread for pictures of the job)
- Corbeau A4 seats

From the stereo shop to my house isn't but 13 miles but I could tell the exhaust sound was not inside the car like it was but behind it. Lots of imporvement from what it was. The girl that does the install said the sound would be better along with the heat and AC.
Have not been on here long but already see there is a big difference in prices in different places and the total install of the sound deadening and she had to do a new install on my stereo dew to the first shop screwed it up was under 300 dollars. She felt it would take a kit and a half, ended up being two full kits after we did the doors and we lined all three back compartments in the trunk with it also. Went this far I wanted it everywhere.
I like it. Have not had the miles to see how much difference it will be but from what I see so far i'm glad we did it.

"As far as the decibel reading - Mike said I lost 10db's in the cabin sitting in it at idle. For whatever that's worth."
A 10 dB reduction means the audible sound is one half what it was previously.
