I totally corroborate your assertion that the M4 is one of the best, if not best looking, M cars ever made.
My '18 ZCP M4 was kitted just like yours with the complete M perf aerokit plus black trip6 wheels. There's nothing cleaner than a 100% factory setup so only props sent your way should you choose to stay the same for duration of your ownership.
Having said that, in the course of a year, I finally did decide to exchange the factory ZCP exhaust for an AA mid-pipe + Remus combo. I put trust in
Justin.AutoTalent's recommendation and it's my fav mod to date. Stock quiet in efficient mode. A deeper/cleaner ZCP note x50 with a dip of the throttle. No oddball aftermarket functional niggles or abnormalities observed so far; none expected.
Thanks for the video, brotha!
