EA111 1.4 TSI Stainless Steel Sports Cat Downpipe | VW Golf Mk6, Audi A3 8P, Seat Leon Mk2 – Midnight Performance

Midnight Performance EA111 CAX 1.4 TSI Stainless Steel Sports Cat Downpipe (PQ35)

The road-legal performance upgrade for your single-turbo EA111 CAX engine. The Midnight Performance EA111 Sports Cat Downpipe replaces the highly restrictive factory catalyst with a high-flow sports catalytic converter — improving exhaust flow and turbo response while retaining a catalyst for emissions compliance. Designed for Stage 1 through Stage 3 setups on the EA111 PQ35 platform.

Key Features

• High-flow sports catalytic converter — significantly less restrictive than OEM, retains a cat for road use
• 2.25-inch (57mm) mandrel-bent T304 stainless steel — smooth bore, corrosion-resistant
• TIG welded construction — strong, leak-free joints
• Improved turbo response — reduced backpressure for faster spool and sharper throttle
• Sportier exhaust note — more character without compromising refinement
• Road-legal alternative to a full decat
