” The M3 GT 500 succeeds perfectly well in completing the difficult balancing act between the fast club sport racing element and the element of the representative “Boulevard-Beau“: from a purely visual point of view, Leib Engineering has maintained a pleasantly cautious posture in the high-grade finishing of the M3 relying only on selected OEM carbon fiber parts that sharply contrast the alpine white paintwork: the carbon flaps under the front spoiler, side-view mirror made of carbon and the tear-off edge also made of carbon on the trunk cover are all taken from BMW’s Performance Program.
One absolute highlight of the vehicle is the in-house valve exhaust system (made of high-grade steel) as from the manifold, which covers a 100-cell HJS catalyzer, an X-pipe with middle silencers and an end muffler with vacuum-controlled Pierburg valves. The sound of the system is controlled through the M-key. The performance boost – in the opened or closed state of the valve – thus generated amounted to a good 27.5 Horse Power as a result of its special design. Further 25 Horse Power is generated by Leib Engineering through the optimization of the engine software in such a way that altogether, a good 470 Horse Power is sent in the direction of the drive train – Suction Tuning par excellence. ”
