Planning on picking up a 2018 Focus ST3 with 26k miles in the next couple of days. The car has some mods, which includes Cobb Stage 1 Power Package (Accessport tuner, RS intake and rear motor mount) and a Flowmaster Outlaw catback exhaust. Wondering if the car is still under warranty. If not, would the dealer still service the car under warranty for issues not related to the mods (synch3, etc).
