Hide what you can, secure what you can
Take it in and ask they not stop at noise and ride height. (90db @3000RPM, 100mm clearance from front to rear)
Shops hear you drive in and say too low/too loud for starters.
Realistically from what you have posted.
- Coil overs - adjustable ??
- turbo timer (hide)
- boost controller (hide)
- Pod filters (secured/coverd)
- Exhaust -
Plus any other defect items as per regs
I think it's best to find the fail points and target your effort and dollars.
Trying to second guess will get you so far, may get you over the line, won't stop you from being defected tho.
