SMS is proud to offer these Kleemann Headers (without downpipes)
“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 the original downpipe. 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.”
These headers are for off-road use only, by purchasing these products you agree that they are for track use only and can not be used on public roads.
