i have had my m2 for a couple months now and went straight into adding a bunch of bolt ons from delivery. Getting used to the power i guess and looking for more without getting too far down the rabbit hole

currently running
-race chip
-tfl full exhaust
-Project Gamma Front Mount Intake


i am not running downpipe’s and thinking that would be the next step but i would be running something with High flow cats. i do pick up my kids sometimes in the car and we line up and idle. lots of kids around and don’t want to be that guy poisoning a bunch of little kids

do you think the downpipes will yield any noticeable power difference?


other option would be going full tune. i would of done it much earlier but really suprised the ECU still needs to be sent to another country to unlock. hard to imagine nobody else has figured it out yet

i have a automatic for reference

active autowerke catted downpipes , no CEL guarantee
E85 if possible
flash tune if you are okay with sending your DME to Finland
Port Injection
Upgraded turbos

jb4 and e30 blend is the best bang for buck. For reference 60-130mph times:

Stock:10.5s
Racechip: 8.5s
JB4 e30: 6.8s
downpipe e50 flash tune: 5.7s

My car had exhaust and intakes for the racechip and jb4 runs. The jb4 isnt perfect but i beat the hell out of my car with it for 10k miles and never had to do more than clear annoying wastegate codes every now and then.

when you say jb4 isn’t perfect can you please elaborate?

It's a very crude low tech way of tricking a very advanced and complicated system into unknowingly adding more boost and timing.
