Evolution exhaust system for BMW M6 (E63, E64)
    |
Our engineers developed a complete exhaust system for the M6. The connection tubes of the Evolution System, i.e. the complete ex manifold system, are newly designed in order to optimize the exhaust flow by offering a bigger tube diameter, interference crossover tubes to improve the vibration characteristics of the exhaust, and the discard of the second set of catalysts. The end mufflers are now split. This technique reduces the weight by 24 kg in comparison to the 44 kg for the stock system.

Performance
The stock torque curve of the M6 V-10-cylinder has a dent in the area of 5000 rpm. Akrapovic exhaust has the cure as the maximum torque increase of 15 Nm (at 6030 rpm) is exactly within that area. The increase of power by 14 HP nearly homogeneously tunes in at around 4000 rpm. This can be felt considerably and the 1800 kg heavy vehicle appears more dynamic. The deconvolution of sound played a key role in the development of the exhaust system. We were able to change the sound characteristics of the high speed concept engine, based on the V-10-cylinder F1 motor, so that the advantages of the race ‘genes’ manifest considerably without appearing invasive in daily use.
Evolution complete system:
- titanium end muffler, with TÜV
- 4 titanium end tubes, with TÜV

Hard facts:
- plus 14,4 HP (at 6360)
- plus 16,7 HP (at 5970)
- minus 26,45 kg (when compared with stock)
