I am pretty sure this time it will be included with GT2 package in USA and Limited package in Canada. For Korea they have
2.5 Turbo Platinum (about 32k USd)
2.5 Turbo Masters (about 35k USd)
3.3 Turbo Masters (pretty much same spec as the 2.5 but the engine) (About 39K USD)
3.3 Turbo Masters with "Turbo Package" (About 43k USD)
The Turbo package add electronic variable exhaust valve, electronic control suspension, red caliper Brembo brakes, head-up display, 360 degrees surround view, and Lexicon audio.
So if they follow the same pattern in North America GT2 and Limited trims should have the variable Exhaust but the base GT should not have the variable Exhaust.
I believe a factory fitted variable Exhaust is ideal because for light “modders” they can do Intake / JB4 or Intake / JB4 + Secondary or resonator delete and have a pretty decent setup. For more involved “modders” the aftermarket solutions will probably be able to connect to factory vacuum / factory ECU managed and avoid additional OBD2 solution or buttons to control the valves!
All this is ideal for a drone free setup. MBRP is nice but tame if you keep every other exhaust component stock but as soon as you start deleting cats or resonators to get more sound out they start to drone.
