Audi S3 (8V) 5 Door Sportback (Non-Valved) (13-18) Turbo Back Performance Exhaust

This Audi S3 performance exhaust is made in 3"/76.2mm pipework and fits from the turbo backwards (Turbo back system) these exhausts replace the front pipe, standard catalyst, centre and rear sections.

The resonated sports exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust is also available as a non-resonated version (excluding the centre silencer) which is a louder option, as it excludes the centre silencer and therefore, has a sportier exhaust note.

The de-cat exhaust version is sold for motorsport and off road use only worldwide.

The sports catalyst version replaces a factory emissions device and is not EC homologated. This may not meet current emission laws for road use in your territory. 

All relevant fittings and gaskets are supplied. (Except turbo clamp).

Note - The fitted images only show the resonated cat-back system.

Please Note - This performance exhaust removes the use of exhaust valves. When switching drive modes (e.g. Comfort to Dynamic mode) your exhaust tone will not change from quieter to louder as before. Using a Non-Valved exhaust will not harm the running of your vehicle, you will simply not have exhaust sound options, however the Cobra Sport exhaust has been designed with this in mind.

This exhaust is also available as a 'valved' option, please see related items.

Note: This product fits Non-GPF models only, please see alternative listings for GPF models.

Cars of the calibre of Audi's S3 require more careful consideration prior to development of a performance enhancing exhaust system. Both Cobra Sport's Technical and Research and Development teams were involved in the planning and preparation that went into the product testing and development of this new system to ensure that the correct balance was achieved between aesthetics and power to make the most of the S3's 2.0 TFSi engine.

The Cobra Sport system delivers significant power increases, but its glory has to be in the weight saving achieved. Swapping the Cat-back system results in a staggering 30% reduction in weight from the OE system's 26.9kg, with the Cobra Sport alternative weighing in at 18.8kg on like for like components.

You can be assured of only the highest quality materials being used in the production of all Cobra Sports exhaust systems with the highest quality grade 304 stainless steel used throughout the components and each exhaust being hand finished and individually TIG welded at our Sheffield factory. The levels of quality achieved enables us to offer a lifetime guarantee on all exhaust systems which provides the ultimate piece of mind for the customer.

The Cobra Sport's quad exit system benefits from a choice angled tailpipes which can be finished in either matt black or original highly polished stainless steel. The end result of this attention to detail, is an ultra-lightweight system which compliments the S3's body styling and sporting pedigree while delivering enhanced performance and handling capabilities.
