Kleemann high flow exhaust headers with cat-less downpipes greatly reduce exhaust gas back pressure and temperatures, allowing the engine to breathe freely and produce more power. Our headers feature smooth mandrel bends, sequenced 4-into-1 merge collectors, precision TIG welds and are produced from 304 stainless steel, polished to a high shine. Supercharged as well as normally aspirated engines will benefit from our headers.

Requires a cut and weld into original down pipe. An ECU Upgrade is a must in order to keep off the MIL Light.

The Kleemann header Kit adds approx. + 25-35 HP across the rev. line, depending on whether it is normally aspirated or a kompressor model.

• With a “normally aspirated car” you will need this ECU Upgrade or the Kleemann Supercharger.
• If you have an AMG kompressor model,  you will need this Kleemann Boost Kit at stage 1.
