Audi A3 (8P) 2.0 TFSI Quattro (3 Door) Turbo Back Performance Exhaust

Turn your A3 8P 2.0T AWD 3‑door into a sharper, harder‑charging hatch with a full stainless system that runs from the turbo outlet to the tailpipes. This Cobra Sport upgrade uses 3 inch 76.2 mm pipework for serious flow, a richer tone and a cleaner look, giving your quattro the soundtrack and response it deserves.

Why enthusiasts choose this system

• 3 inch 76.2 mm stainless pipework from turbo to rear section for maximum gas flow and throttle response
• Direct‑fit design for the A3 8P 2.0 TFSI quattro 3dr, engineered to work with the OEM mounting points
• Two sound levels: resonated for subtle refinement, non‑resonated for a deeper, louder, sportier note
• Choice of sports catalyst or de‑cat downpipe to suit road or track use
• All fixings and gaskets supplied, except the turbo gasket

Configuration options for your 8P 2.0T

This downpipe‑back setup replaces the factory front pipe, centre section and rear box.

• Resonated: includes centre silencer for a refined, OE‑plus character on the motorway with a purposeful growl when you press on.
• Non‑resonated: removes the centre silencer for a more aggressive tone and increased cabin presence.
• Sports catalyst: replaces the stock emissions component with a performance cat. Not EC homologated.
• De‑cat: straight‑through section for track and off‑road use only. A performance remap is required to realise full gains.

Real performance gains

On the most focused setup (turbo to tailpipes with de‑cat and suitable ECU calibration), testing has shown headline results of up to 290.5 bhp with torque rising to 292 lb‑ft. That is a substantial uplift in both mid‑range punch and top‑end pull compared to standard.

Sound you will love

The resonated system adds around 3 dB on drive‑by compared to stock, keeping motorway cruising civilised while unlocking a richer tone. Want more character? The non‑resonated option brings a deeper, more assertive soundtrack without the drone you get from cheap systems.
