Unitronic is proud to release its Cat-Back Exhaust System for the  8V and 8V.2 Audi S3 equipped with the 2.0 TSI MQB engine. This Valved Cat-Back Exhaust System 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, your choice of either polished round, or black round 4-inch  slash cut exhaust 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 unobtrusive exhaust tone inside the cabin.

Consistent with all of its performance products, Unitronic utilizes only the latest industry-leading tools, equipment, and computer-aided design software that are packed with the latest technology from our technology partners at Creaform® and Stratasys®. Operations start with 3D scanning the MK7/MK7.5 Golf R and 8V/8V.2 S3 chassis, exhaust tunnels, mounting locations, and rear diffuser/bumper assembly, along with the OEM components using its in-house 3D scanner. Once 3D scan data has been collected and processed, Unitronic Hardware Engineers then interact with the 3D models to identify fitment constraints, mounting locations, other component locations, etc. to ensure the final product fits perfectly within the “envelope”.

Design

Exiting at the rear, exhaust gasses pass through available  4” round, slash cut polished or black tips which are compatible with the Golf R and S3 for a more aggressive, motorsport-inspired look.

In order to accommodate the longer rear bumper and diffuser of the S3, Unitronic Engineers designed S3-specific tailpipe tubes, which are longer than the Golf R versions and offer the same valve functionality with multiple tip options.

Like all Unitronic Performance Hardware, this Cat-Back Exhaust System offers direct bolt-on fitment, retaining the factory mounting locations in order to simplify the installation process. It also carries a Limited Lifetime Warranty to the original retail purchaser against manufacturing defects or craftsmanship flaws as well.
