Audi TTS (Mk3) 2.0 TFSI Turbo Back Performance Exhaust

Transform the drive, soundtrack and look of your Audi TTS Mk3 2.0 TFSI with this full Cobra Sport stainless system, engineered from turbocharger to tailpipes for the ultimate upgrade.

Built for the Coupe model, this big-bore 76.2 mm 3 inch setup replaces the factory front pipe, centre section and rear box with precision-made T304 stainless components that flow, fit and last. Expect a deeper, richer note in daily driving that turns razor-sharp and aggressive under load, with outstanding build quality and a lifetime guarantee for the original purchaser.

Why choose this Cobra Sport system

• Serious sound, zero drone – refined on cruise, fierce when you want it. Sound testing on the resonated cat-back showed a +4 dB increase at 4,000 rpm and +9 dB at idle over stock.
• High-flow design – mandrel-bent pipework for smooth gas velocity and response, ideal for tuned cars and future Stage 2 plans.
• Weight saving – up to 39 percent lighter than OE. The 3 inch non-resonated cat-back is just 10.95 kg vs the original 17.95 kg. The de-cat front pipe weighs only 7.57 kg, around 20 percent lighter than standard.
• Craftsmanship you can see – hand-finished TIG welds, CNC mandrel bends and precision jigs for an exact fit every time.
• Built to last – premium 304-grade stainless steel throughout with a lifetime warranty from Cobra Sport.

Choose your sound and control

• Valved – retains the factory valve control. Keep drive-mode sound changes through the OE motors and electrical connectors for quiet-to-loud switching as before.
• Non-valved – removes the valve hardware for a consistent, more intense soundtrack. Drive modes will no longer alter exhaust volume.
• Resonated – includes a centre silencer for a subtle, refined tone on the motorway with a purposeful growl under throttle.
• Non-resonated – deletes the centre silencer for the louder, raw option.

Options and compliance

• De-cat/downpipe – sold for motorsport and off-road use only worldwide.
• High-flow sports catalyst – replaces the factory emissions component and is not EC homologated. May not meet current road-going emissions regulations in your territory.

Fitment

Designed for the Audi TTS Mk3 2.0 TFSI Coupe only. Supplied with all necessary fittings and gaskets for a straightforward installation.
