宝马 E70 X5 4.8i V8 (N62) '07 -> '09

The Supersprint 4-into-1 long tube headers system offers a huge performance improvement over the awfully restrictive, log-design stock manifolds with integrated catalytics.

They totally turn the exhaust gas flow dynamics around, guaranteeing a major gain in performance throughout the entire rpm range, from 1500 rpm all the way to redline.

The gains in peak hp are averaging +20 / + 30 Hp, with highs of + 40 Hp in specific areas of the midrange.

The torque grows by + 30 / + 60 Nm, with a continuous, virtually even spread over the entire powerband.
