2015 Focus ST.

Installed parts:
Roush Intake system
Cobb downpipe
Turbo smart BOV
Cobb lower engine mount
Cobb symposer delete

I just received my Accessport in the mail and didn't realize a
Requirement for stage 1 was a catback exhaust. Obviously
It's something I will get eventually but funds are holding me
Back right now. Is it safe to tune up to Stage 1 87/91 without
The cat back system? Any information would be appreciated.

Thank you! ???
