EA111 1.4 TSI Single-Turbo Stainless Steel Decat Downpipe | VW Golf Mk6, Audi A3 8P, Seat Leon Mk2 – Midnight Performance

Midnight Performance EA111 1.4 TSI Single-Turbo Stainless Steel Decat Downpipe (PQ35)

Unlock the full tuning potential of your single-turbo EA111 engine. This T304 stainless decat downpipe eliminates the restrictive factory catalytic converter — slashing backpressure directly behind the turbocharger for faster spool-up, sharper throttle response, and a deep, aggressive exhaust note. The perfect foundation for Stage 2 or Stage 3 ECU calibrations on the PQ35 platform.

🚫 For off-road and track use only — not road legal in the UK.

⚠️ NOT compatible with 1.4 TSI Twincharged engines (CAVD, CTHE — typically 140–180bhp). PQ35 platform only — not for PQ25 vehicles (VW Polo, SEAT Ibiza).

Key Features

• T304 aircraft-grade stainless steel — polished, anti-corrosive finish
• 2.25-inch (57mm) mandrel-bent piping — smooth, unrestricted exhaust flow
• Precision TIG welded with CNC machined outflow flanges
• Integrated O2 sensor boss — clean sensor fitment, no relocation needed
• Straight-through decat design — zero catalyst restriction
• Stage 2 remap recommended — maximise gains and clear engine management lights
