Description
The high revving 4.2L V8 engine takes significant advantage of the 4-1 Supersprint headers design and its step diameter, larger than stock, primary tubes.
We have designed a specific, dual-pipe 70mm oversize exhaust to complement it.
This Supersprint full system has a capacity of 600+ Hp.
Fitment is simply perfect within the tight confines of the RS4 engine bay, with no modification required on either the Sedan, Avant or Convertible versions.
Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
