I have recently purchased a 2020 challenger R/T. I am buying kooks 2” long tube headers but still lost on which full exhaust system is the best? Any recommendation would be appreciated.

Main considerations:
  • Borla ATAK
  • Kooks exhaust
  • Corsa exhaust

I am currently running a 5.7 (6.2 cam) with SW 2" headers (running a magnuson SC), high flow cats and 2.5" corsa extreme with mid muffler delete. Sounds very health and mean but will be upgrading to the AWE 3" 6.4 catback system (no mid mufflers..they call it resos).

I wouldn't get 2" headers unless you're gonna add boost. If 1 ⅞ is enough for a hellcat it's enough for a 5.7. You'll lose exhaust velocity and very possibly make less power compared to 1 ⅞ especially with a stock cam.
