Many cars running jb4 with stock pipes without problem. Unless you want to add meth injection then the charge pipe is a must.
Best to check with Evolve in the requirement details. I know Ian's car has fmic + exhaust and it only runs stage 1.
No issues with transmission due to tuning I have come across in the last few years.
