Milltek has released a new exhaust for the B8 RS4. Milltek’s engineers report that they were keen to maintain the all-round character and usability of the RS4, whilst injecting a little more drama – and power – into proceedings. Two systems will be made available upon launch; a primary cat back, with full EC homologation and approval for those looking to keep things ‘OEM+’ and a wonderfully toned non-resonated system that offers a perfectly pitched rasp and growl, but without the in-cabin resonance and droning of lesser systems.
