Audi TTS (Mk3) 2.0 TFSI Cat Back Performance Exhaust

Unlock the soundtrack your Audi TTS deserves

Give your Audi TTS Mk3 8S 2.0 TFSI a proper voice with this high-grade stainless steel rear system from Cobra Sport. Designed to run from the catalyst backwards, it replaces the mid and tail sections with free-flowing 76.2 mm pipework for a deeper, more engaging tone and a quality finish that looks as good as it sounds.

Fitment: Coupe models only. Quattro compatible.

Why owners choose this upgrade

• Richer, sportier note without drone on the resonated option. Louder, more aggressive bark on the non-resonated option.
• Genuine weight saving over the bulky factory system. The catback package drops to just 10.95 kg vs 17.95 kg stock, a reduction of around 39 percent.
• Proven sound testing on the resonated setup shows approximately +4 dB at 4,000 rpm and roughly +9 dB at idle compared to OE.
• Precision build quality using Grade 304 stainless, TIG-welded and mandrel bent for smooth gas flow and long-term durability.
• Direct replacement installation with all required fittings and gaskets supplied.
• Backed by Cobra Sport’s lifetime guarantee for the original purchaser.

Choose your sound

• Resonated includes a centre silencer for a refined, performance-led tone that remains civilised on the motorway.
• Non-resonated removes the centre silencer for a noticeably louder, more motorsport-inspired character.

Valved vs non-valved

• Valved system retains the factory valve control. Switch drive select modes and your exhaust note moves from calm to more spirited, just as it should.
• Non-valved system omits valves. The sound remains consistent across modes. This does not harm engine operation; you simply do not have variable sound control.

Developed for enthusiasts

Crafted by Cobra Sport’s experienced team, this catback is track-developed and road-ready. The combination of high-quality materials, precision jigs and careful acoustic tuning delivers a premium feel every time you drive. The product family also includes a de-cat front pipe option weighing just 7.57 kg for those building more extreme, off-road or track-focused setups, opening up further tuning headroom.
