The late '70s and early '80s were incredible years for the BMW high performance enthusiasts.

The Hartge H3 was one of the first E21 cars ever equipped with the larger displacement M30 3.5L engine, taken from the 635csi.
This engine conversion, along with the suspension, chassis, drivetrain and brake upgrades made the E21 one fast car.
It became the car that every E21 owner was dreaming of.
Supersprint was the proud manufacturer of the Hartge special exhaust, back at the time, and we still handcraft the same system 40 years later.
Our "Fächerkrümmer" (tubular headers) was the magic component of the entire system, making substantially more power and torque over the cast iron manifold.
No less important, the resonator and the R&L mufflers did guarantee free flowing, providing for the perfect sound at the same time.
