Cupra Leon 2.0 TSI 300 (20>) Front Downpipe Sports Cat / De-Cat Performance Exhaust

Transform the soundtrack and flow of your Cupra Leon 300

Give your Cupra Leon 2.0 TSI 300 the voice and breathing it deserves with this high-flow turbo downpipe assembly, engineered specifically for 2020 on KL1 models with GPF/OPF. Choose between a 200 cell sports catalytic converter with a 4.5 inch core for fast-flowing performance or a catless race pipe for maximum gas velocity on track-only builds.

Why owners choose this upgrade

• Serious flow gains from precision mandrel-bent 3 inch 76.2 mm tubing that reduces back pressure and frees up tuning headroom.
• T304 stainless steel throughout with neat TIG welds for strength, durability and a premium finish.
• 200 cell 4.5 inch 114.3 mm sports catalyst option delivers excellent gas speed while keeping the tone civil on cruise and punchy on throttle.
• Catless option for dedicated track builds seeking the most aggressive response and exhaust character.
• Designed to mate to the factory system or Cobra Sport GPF back and cat back systems, making future upgrades easy.

We have fitted this system on customer cars and our own demonstrators. Feedback has been consistently positive about the richer exhaust note, sharper turbo spool and the top tier build quality. If you want a Cupra that sounds as potent as it goes, this is the go to front pipe upgrade.

Important usage and emissions information

• De cat version: for track and off highway use only worldwide.
• Sports cat version: replaces original emissions hardware and is supplied without EC type approval. Road legality varies by territory and it may not comply with current emissions legislation.
• This assembly removes the GPF/PPF. An ECU calibration is required at installation to prevent a check engine light on vehicles fitted with a particulate filter.

Perfect for enthusiasts planning future upgrades

This front pipe works brilliantly with further modifications such as a GPF back system, intake, intercooler and a performance remap. The freer flowing design supports strong tuning potential from the EA888 powered Leon 300 while delivering a deeper, more purposeful tone.
