M5: Evolve-R Tune, RPi Scoops (My old motor).
5.0: Intake, Tune, OR H-Pipe, Resonator Delete, GT500 Axle Back Exhaust, 3.31 Gears.
Since then the M5 received a Stage II Evolve-R tune and a secondary cat delete:
M5: Evolve-R Stage 2 Tune, RPi Scoops, Muffler & Secondary Cat Delete.
5.0: Intake, Tune, OR H-Pipe, Resonator Delete, GT500 Axle Back Exhaust, 3.31 Gears.
It looked like the Mustang had an advantage from the low speed 20 mph roll but once the M5 stretched its legs in the 50 on MPH rolls it walked away from the Mustang. Definitely a strong top end on the S85.
Thanks to BimmerBoost member @TZ04XJR for the videos.
