Just got a 2016 bmw m235

Just got a bmw m235 about a month ago and I already got a stage 1 from BMP, a race intercooler from vsrf, and a exhaust from vsrf and was curious if my next modification should be a intake or a catless downpipe, and what other mods should I get after that. Also kind of curious what kind of power i’m pushing if anyone wants to make an estimate lol
