Milltek Releases Audi RS4 B8 4.2 V8 exhaust
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.
Through extensive dyno and road testing, the system diameter was optimised at 2.37” / 60.3mm and fabricated from the highest grade austenitic stainless steel to ensure the perfect compromise between maximum gas-flow and ideal back pressure. The system also utilises Milltek’s latest ‘ValveSonic’ technology, featuring active valves that work seamlessly with the OEM vacuum system, even integrating with the Audi Drive Select system to activate the valves at different RPMs and loads based on the selected engine mode. All very clever stuff, but with everything happening automatically, all the driver has to do is sit back and enjoy the sound. Prices start at £1672.11 + VAT.
