The naturally aspirated 392 is the Challenger that benefits most from exhaust work, because there is no supercharger covering up what the engine is doing. ATAK tuning takes it to the loudest level Borla builds, the merge x-pipe evens out the firing pulses, and the factory active valves are retained so the car is not permanently committed to that volume.
