Unitronic Turbo Back Exhaust System for C7 | C7.5 Audi S6 4.0T - (NLA)

Unitronic is pleased to present its 2.5" Turbo-Back Exhaust System for the C7/C7.5 Audi S6. Featuring TIG welded T304 Stainless Steel CNC mandrel bent construction, stainless steel corrugated flex section, high flow 200-cell metallic catalytic converter, and a free flowing design; Unitronic’s Turbo-Back Exhaust Systems are designed to remove the factory exhaust restrictions to unleash the full potential of the engine.

Like all of Unitronic’s Performance Exhaust Systems, a unique v-band fastener system, using T316 Stainless Steel flanges was utilized to ensure a leak proof connection every time. This is achieved through a locking ring on all Unitronic v-band flanges to guarantee a centric alignment of the two flanges. Unitronic’s mufflers feature a high density, high temperature glass fiber packing and are stamped with the Unitronic logo. These attributes combined ensure maximum performance, while maintaining a comfortable and unobtrusive tone inside the cabin. Exiting at the rear, exhaust gasses pass through dual 3" slash cut tips and engraved with the Unitronic logo.
