1) Depends on the engine... noticeably louder than stock for something with 6 cylinder, aggressive (pretty much a straight pipe) for anything with more.

2) Satin Black with Carbon Fiber ones if I had some spare cash to get them

3) No real preference so probably the 409.

4)
Flow requirements
Horsepower/Torque
System longevity
Weight Reduction

If sound was an option for question 4 that would be my top answer however.
