Unitronic® is proud to release its Cat-Back Exhaust System for the MK8 Golf R® and 8Y S3® equipped with the 2.0 TSI® EA888® EVO4® engine. This Valved Cat-Back Exhaust System features 3-inch T304 Stainless Steel mandrel bent tubing, high density, high temperature fiber glass packed muffler with acoustic design inspired by the OEM Audi Sports Exhaust for the 8V.2 RS3, your choice of polished oval, polished round or black PVD*, round 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 MK8 Golf R or 8Y S3 cabin.
At Unitronic, development begins with setting the objectives; performance, efficiency, aesthetics and quality. Operations start with 3D scanning the engine bay, exhaust tunnel and OEM components of our in-house MK8 Golf R and 8Y S3 development vehicles. 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”, while achieving the objectives and intent of the product.
Throughout the research and development phase of this MK8 Golf R exhaust system and 8Y S3 exhaust system, sound both inside and outside the cabin are also very important factors. 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 fiber glass packing to ensure maximum performance and a sportier sound are achieved while maintaining a comfortable tone inside the cabin.
Exiting at the rear, exhaust gasses pass through available 4.5” oval tips for the Golf R Cat-Back or 4” round, slash cut polished or black PVD* tips for the Golf R and S3 Cat-Back for a more aggressive, motorsport inspired look.
In order to accommodate the longer rear bumper and diffuser of the 8Y S3, Unitronic Engineers designed specific tail pipe 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 looking to obtain a sportier exhaust note which 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.
Unitronic Exhaust Systems feature a unique sealing v-band fastening system that uses T316 stainless steel flanges and a locking ring to guarantee a centric alignment of the two v-band flanges which ensures a leak proof connection every time.
Like all Unitronic Performance Hardware, this MK8 Golf R Exhaust System and 8Y S3 Exhaust System offers direct bolt-on fitment, retaining the factory mounting locations in order to simplify the installation process. They also carry a Limited Lifetime Warranty to the original retail purchaser against manufacturing defects or craftsmanship flaws as well.
