Congratulation for graduating and you car.
As for exhaust I own Solo Performance MACH X LLT wity J Pipes.
Especially done for V6 Camaros, no drone at 70MPH, excellent quality and last I heard 899,00$ shipped in USA.
IMO I think that Spalsh Guards from GM is my best investment to prevent paint chips at the gills level and keeps the car cleaner much longer....
Here are some pic.
