Description
The Unitronic 3-inch Performance Cat-Back Exhaust System for the Audi 8V A3 Quattro is engineered to deliver maximum performance, sound, and reliability. Built from T304 stainless steel mandrel-bent tubing with CNC-machined T316 stainless steel v-band flanges, this exhaust ensures a leak-proof, perfectly aligned connection with every installation.
Unitronic’s free-flowing mufflers feature high-density, high-temperature fiberglass packing and a straight-through design for optimal exhaust flow. Combined with Sound Reflection Chamber and Sound Absorption technologies, the system produces a deep, refined exhaust note while maintaining comfort inside the cabin.
Finishing the system are dual 3.5-inch double-walled polished tips, laser-engraved with the Unitronic logo, providing an aggressive look that complements the performance gains.
