The most high exalting and I ain't haltin'
Till I die of exhaustion, inhale my exhaust fumes
Eminem feels exhilarated when he raps. He will only stop/halt the day he dies from exhaustion. He functions like a machine, and his raps are like fumes coming out of him. Everyone else will inhale his exhaust fumes because they are trailing behind him. Every upcoming rapper will inherit his legacy.
Also, some drug-related wordplay with “high” and “inhale fumes”.
