Default engine noise and rattle

@ 4k rpm,, the engine produces so much noise through the firewall and rattles right under the shifter,, is that common in manual C5 with C6Z shifter, long tubes and exhaust?

The first area I would check is for proper installation of the headers and exhaust system (rubbing on frame components, loose fasteners etc...), then I would check for drive line components that could cause vibration.
