Tuned E60 M5 versus W211 E55 AMG with exhaust and stock C6 Z06 from a roll
Great run videos here from BimmerBoost member TZ04XJR. He has the E60 M5 which is the camera car in the videos and his modifications consist of an Evolve R-Tune, RPI Intake, and a muffler delete. The E55 AMG has an exhaust which is not named and the C6 Z06 is completely stock. The M5 makes fairly easy work of the E55 AMG which is to be expected of a car that just has the exhaust versus a tuned M5 which shows its strength from a roll even when the E55 gets the jump.
The Z06 though easily dispatches the M5. This is to be expected for the much lighter Z06 which even stock will be putting out similar power to the rear wheels. Even with headers and a full exhaust the M5 would have trouble. The Z06 is simply a beast.
Great runs, thank you to @TZ04XJR
