RANGE ROVER L322 4.4i V8 '02 -> '04 (Motor BMW)

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.
