I have started the construction of the database as a spreadsheet won't do what I need it to.
For those who want to post the information please provide the following:
Car:
Year, Stock Model configuration (GXL, GTU, etc), and a short list of modifications that may affect exhaust level (porting, turbo, custom manifolds and/or exhausts).
Exhaust components:
Manufacturer, Model Number, Style (Perforated Tube, Chambered, etc), Inlet number, Inlet Size, Outlet number, Outlet size, Offset (yes/no)
interior db data:
db reading at idle (or 1000 rpm), 3000 rpm, 4000 rpm, 5000 rpm, 6000 rpm.
Those measurements are to be done stationary to remove wind-noise or other forms of noise from measurement.
Exterior db data:
Measure 6 ft back from the rear wheel for recording and record the same db levels for the various rpm (idle, 3000, 4000, 5000, 6000).
