BMW E39 Limousine 535i / 540i V8 (M62) '96 -> '02

The Supersprint 4-into-1 long tube headers system offers a substantial performance gain over the restrictive, log-design stock manifolds.

They improve the exhaust gas flow dynamics dramatically, guaranteeing a major increase in peak hp, and in mid-range torque as well.

The gains are averaging +20 / + 25 Hp on top, and + 20 / + 40 Nm torque, from 3000 rpm to redline.
