Audi S7 Sportback 4.0 TFSI quattro S tronic From 2012 To 2018 Large-bore Downpipes and Cat Bypass Pipes - Milltek Sport

Milltek Sport Large-Bore Downpipes are perfect when looking to improve both performance and sound. These downpipes are fabricated with a larger diameter than standard OEM parts, meaning that there is significantly more space for more gas to exit the engine and pass through, increasing efficiency. We also remove the primary catalyst from the exhaust system to create more of a freer-flowing exhaust, allowing the engine to operate more efficiently and to increase performance. - For Track Use Only! - 76mm Downpipes with cat bypass pipes for highly tuned cars - Requires Lambda extensions leads - Must be fitted with the Milltek Sport cat-back system - Requires a stage 2 ECU remap.

Please note this exhaust is designed for motorsport use only. You will not pass a UK emissions test or police road side check with this exhaust installed on the vehicle.
