Audi TT Mk2 8J 2.0 TFSI Quattro 2012-2014 Turbo-Back Exhaust | 3in/76mm Stainless Full System with Downpipe | Cat-Back, Sports Cat 200-Cell or De-Cat | Resonated or Non-Res | Stage 2 2.0T Coupe S-Line Dual Exit

Transform the character of your Audi TT 8J Quattro 2.0 turbo petrol with a complete exhaust upgrade that runs from the turbo outlet right back to the tailpipes. This full-length stainless system delivers sharper throttle response, a richer tone and serious tuning potential for the 2012 to 2014 facelift quattro Coupe.

Why enthusiasts choose this system

• 3 inch, 76.2 mm pipework from turbine housing to rear section for improved flow and reduced backpressure
• Choice of resonated or louder non‑resonated centre section to tailor sound
• Available with a high‑flow sports catalyst or a motorsport de‑cat option
• Proven gains when paired with appropriate software, with significant increases in bhp and torque reported by the manufacturer on a comparable setup
• Refined in‑car acoustics with a deeper, sportier note outside

Fitment and compatibility

• Vehicle: Audi TT Mk2 8J, 2.0 TFSI quattro, model years 2012 to 2014
• Body style: Coupe only
• Rear valance: S‑Line bumper with dual exit lower panel required
• Drivetrain: quattro all‑wheel drive

Configuration options

• Sports catalyst system – high‑flow cat for enhanced performance while maintaining a cleaner tailpipe smell compared to de‑cat
• De‑cat system – track and off‑road use only, maximum flow for Stage 2 style calibrations
• Resonated – includes centre silencer for a subtle upgrade in volume with minimal cabin intrusion
• Non‑resonated – deletes centre silencer for a more pronounced, aggressive exhaust note

Performance and sound

Designed to free up the 2.0 TFSI, this downpipe and system combination reduces restriction from the turbo back, supporting strong power and torque increases with suitable mapping. The resonated option keeps long‑journey comfort intact, while the non‑resonated layout brings out more of the turbocharged character on throttle.
