Unitronic Performance Valved Turbo-Back Exhaust System for Audi 8V/8V.2 S3 (2.0 TSI EA888 Gen 3 MQB)
Unlock the full performance potential of your Audi S3 8V/8V.2 with the Unitronic Performance Valved Turbo-Back Exhaust System. Engineered to deliver maximum power, refined sound, and factory-like fitment, this system combines precision craftsmanship with advanced design for enthusiasts demanding the best in performance and reliability.
At the core of this system is a CFD-optimized upper downpipe equipped with a GESi 5” UHO+ 400cpsi catalytic converter, developed to meet or exceed local emissions testing standards. Exhaust gases flow into 3” T304 stainless steel mandrel-bent tubing, through a straight-through muffler packed with high-density fiberglass wool, and exit via polished 4” round tips engraved with the Unitronic logo. Optional black round tips are also available.
Maintaining OEM convenience, the valved design integrates with the factory valve system, preserving stock driving modes and sound control. Backed by extensive R&D and real-world testing, this turbo-back system provides a deep, refined tone, optimized flow, and long-lasting durability—all without intrusive cabin drone.
