Transform your 8J TTS 2.0 TFSI into a sharper, harder-hitting road and track machine with this full stainless system that runs from the turbo to the tailpipes. Designed for the Coupe with quattro all-wheel-drive, this upgrade delivers a deeper soundtrack, faster spool and beautifully engineered build quality.
Why enthusiasts choose this system
3 inch - 76.2 mm mandrel-bent 304 stainless steel tubing for maximised gas flow and rapid turbo response
Complete solution - replaces the OE downpipe, factory catalytic converter, centre and rear sections
Choice of sound levels - resonated for refined tone, non-resonated for a louder, more aggressive note
Tailpipe options - quad 3 inch or bolder 3.5 inch round tips in highly polished stainless or stealth matt black
Precision TIG-welded, jig-built fitment with all hardware and gaskets supplied - turbo gasket not included
Backed by a lifetime guarantee for the original purchaser
Real-world performance
With a full turbo-to-rear setup using a de-cat and paired with an ECU calibration, manufacturer test figures show gains of up to 35 percent in peak power with torque up by 27.5 percent. The result is a stronger midrange, keener throttle response and a soundtrack that complements the Audi’s premium character without drone when specified with the resonated centre section.
Sound options to suit your drive
Resonated: includes a centre silencer for a subtle, sporty tone on the motorway and an engaging growl under load.
Non-resonated: removes the centre silencer for a louder, more motorsport-inspired note.
Legal and usage notes
De-cat: supplied strictly for motorsport and off-road use worldwide.
Sports catalyst: replaces an original emissions device and is not EC homologated - may not meet current road-going emission requirements in your region.
