This valved Cat-Back Exhaust System for the 8Y S3® features 3-inch T304 Stainless Steel mandrel bent tubing, high density, high-temperature fiberglass packed muffler with an acoustic design inspired by the OEM Audi Sports Exhaust for the 8V.2 RS3, including 4" Polished Round Tips and high-quality v-band fasteners with T316 Stainless Steel flanges.

These attributes, combined with extensive R&D testing, help ensure perfect fitment and maximum performance while maintaining a comfortable and discreet exhaust tone inside the 8Y S3 cabin.

Design:

Throughout the research and development phase of this 8Y S3 exhaust system, sound inside and outside the cabin is also critical. Unitronic Engineers studied the muffler configuration and acoustics of the OEM Audi Sports Exhausts found on the 8V.2 Audi RS 3 and 8S TT RS, which inspired the acoustic design for this application and feature high density, high-temperature fiberglass packing to ensure maximum performance and a sportier sound are achieved while maintaining a relaxed tone inside the cabin.

Exiting at the rear, exhaust gasses pass through 4" Polished Round Tips for S3 Cat-Back for a more aggressive, motorsport-inspired look.

To accommodate the more extended rear bumper and diffuser of the 8Y S3, Unitronic Engineers designed specific tailpipe tubes for the S3 Cat-Back Exhaust System, which are longer than the Golf R versions and offer the same valve functionality with multiple tip options.

This Unitronic Cat-Back Exhaust System can be easily mated to the factory downpipe for customers seeking a sportier exhaust note that retains the OEM valve functionality. Or for the ultimate performance enhancement, this exhaust system can also be paired with Unitronic's Stage 2 Performance Software and upcoming MQB EVO4 AWD Downpipe.
