UNITRONIC TURBO-BACK FOR 8V AUDI A3 QUATTRO
(UH029-EXA)

Featuring TIG welded T304 Stainless Steel CNC mandrel bent construction, stainless steel corrugated flex section, high flow 200-cell metallic catalytic converter, and a straight-through, 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 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.
