宝马 E53 X5 4.4i V8 (N62) '03 -> '06


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 +25 / + 35 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.

Supersprint is proud to offer the best headers system for the Classic BMW X5 4.8is / 4.4i V8.

The N62 engine has huge potential, unfortunately it is chocked down by an overly restrictive factory #exhaust, courtesy of the stringent emission regulations.

This was the first BMW V8 engine equipped with the factory catalytics placed harmfully close to the engine.

This design hurts the exhaust gas flow so bad, that it totally wreacks havoc on the performance, killing both the torque in the low / mid rpm range and the peak hp.

Unfortunately, this exhaust makes no justice to this BMW high peformance SUV.

The Supersprint long tube headers system, with its downstream re-located, high flowing HJS Motorsport catalytics, provides for an astounding gain of + 35 Hp, and + 50 Nm torque.

Also, with the addition of the Supersprint resonator + rear mufflers, the engine finally makes the deep roar everyone is expecting from.

As usual, Supersprint guarantees ease of installation, and a long life, thanks to the multi-piece primary tube design, and the Patented, proprietary floating-flange sealing system.

Each and every Superspint headers and exhaust part is hand built individually, at our Factory in Italy.

Supersprint always means one man, one exhaust.
