This is Real Drifting Initial D

Fake Project D were a duo of unnamed racers that briefly impersonated the real Project D in the Saitama region, until they were exposed by both Wataru Akiyama and Project D, who became aware shortly afterwards.

The posers are seen again in a mountain pass and Wataru approaches them in a friendly chat while Takumi drives his way there. He requests the imposter Takumi to show them a fast drift around a corner. Takumi's imposter tries to tell him no such person can do such thing. Wataru then shows the real Takumi's drifting skills which caused their eyes to widen seeing such spectacle. Wataru saw how much Takumi improved. However, the imposters try to leave but Keisuke stops them. Keisuke and Wataru greet each other in delight and confronts the two of them on trying to ruin their reputations.
