Stage II
2016 M235i auto M performance exhaust and AFE cold air intake (stock downpipe)
355whp@6500RPM
"No downpipe, just muffler and intake. Downpipe doesn't really net much to anything on these cars at that power level. I've posted a 2015 335i (makes less than the m235i b/c it has a more aggressive tune from the factory) With just our stage 2 tune and downpipe.
EDIT: I posted the timestamp to show we did this all in the sameday."
