1969 Camaro Chambered Exhaust Experts

[CamaroNOS]

I have a 69 Z/28 with a 302 (factory solid cam,11:1 compression and headers) a M22, 4:10 or 4:88 (TBD) gears, 15" Polyglas tires and no factory floor insulation. I would like to hear from some experienced members what it will be like running a chambered exhaust system on the car. The pipes are a factory 2 1/4" system and unfortunately I do not know the exhaust system brand.

1. On a scale of 1 to 10 (1 being quiet and 10 being insane), how loud will the interior be with the chambered system without any floor insulation, just a factory carpet? Will I need a bucket of aspirins after driving 20 minutes at 50 mph?
2. I suspect installing the factory heavy sound deadener will reduce the interior noise a bit. If so, to what percentage if you were to guess?
3. Would installing after market sound insulation on the complete interior floor area reduce the interior sound substantially? And if so, to what percentage?
4. If installing after market insulation helps a lot, who makes the best insulation kit for this purpose? Keep in mind I only would put the insulation on the interior floor compartment and not on the interior of the doors, quarter panels or trunk area.
5. Would I be safe to say that trying to listened to my favorite VH album with any form of insulation in the Camaro will be a pipe dream..... haha.
