Unitronic Catback Exhaust System - Audi A3 Quattro (8V) 2015-2020
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.
