Description
Milltek Large Bore Downpipes w/ Hi-Flow Sports Catalyst (For Milltek Cat-Back) Audi S7 Sportback 2012-2018
Milltek Sport Large-Bore Downpipes are engineered to enhance both performance and sound, featuring a larger diameter than standard OEM parts. This increased diameter provides ample space for exhaust gases to exit the engine more efficiently, thereby improving overall engine performance.
Moreover, our downpipes remove the primary catalyst from the exhaust system, promoting a freer-flowing exhaust configuration. By eliminating this restriction, the engine can operate with greater efficiency, resulting in enhanced performance.
Notes:
- Larger-bore 76mm Downpipes with 100-cell hi-flow sports catalysts for highly tuned cars
- Requires Lambda extensions leads
- Must be fitted with the Milltek Sport cat-back system
- Requires a stage 2 ECU remap.
