Show original supplier description
The Milltek Sport SSXAU668 Active Sound Control system is engineered to provide enhanced exhaust sound for specific Audi models. This V2 system offers 8 selectable sound files and features ValveSonic technology for dynamic sound control. This system is specifically designed to fit the Audi SQ7 with the 4.0 V8 TDI engine, model years 2016-2020. It is part of Milltek's commitment to delivering sporty and crisp exhaust tones without inducing cabin resonance or drone. Milltek Sport has over 32 years of experience in exhaust development, with all systems designed, developed, and manufactured in the UK. The use of mandrel bending ensures optimized gas flow for improved performance.
