Hello, just purchased a Camaro ZL1, I am interested in performance upgrades. What is
available for the exhaust (headers & mufflers) and camshaft upgrade? Also, is there a break-in period for the engine before doing upgrades? My goal is 700HP and
the "old muscle car" sound. This is my only vehicle - everyday driveability is very important, let me know how long you would need the car.
Thank You.
