Unitronic Cat-Back Exhaust System for 8V A3 Quattro

Unitronic is pleased to present its 3" Performance Cat-Back Exhaust System for the 8V Audi A3. 

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 with a straight-through, free flowing muffler design. 

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 3.5" Double Wall Polished Exhaust Tips with Engraved Unitronic Logo.
