Exhaust System
The Audi R8 has a very unique downstream exhaust
design. During the development of the exhaust system,
special emphasis was placed on optimizing flow
resistance. The rear exhaust incorporates both post
converters and mufflers in the same assembly.
Another new aspect of this system is that the exhaust
from both banks enter the assembly from their
respective sides but then cross over through assembly
and exit from the opposite side they entered.
