The E63 M6 alongside the E60 M5 were the last of their kinds that were fitted with naturally aspirated engines. And what an engine it was.
The S85 V10 5-liter engine under the bonnet of these cars was nothing short of legendary. Developed using Formula 1 technology, this unit sent up to 507 HP to the rear wheels, having a redline of 8250 RPM.
Since it was derived from Formula 1, the S85 deserved an exhaust that made it sound like a single-seater. That's exactly what the guys from Eisenmann did. They created a number of exhaust systems that create a special sound, perfectly matching the power and agility of the M6.
However, this owner went even further. The Eisenmann system on this car has straight pipes and is decatted for a really loud and intense experience, as you're about to witness in the video below.
