VW Audi Seat Skoda 1.4 TSI EA111 Stainless Decat Downpipe | Midnight Performance

High-Flow 1.4 TSI EA111 Single-Turbo Stainless Steel Decat Downpipe (PQ35 Platform Only)

Unlock the ultimate tuning potential, faster turbo spool-up times, and a highly aggressive exhaust note on your vehicle. The Midnight Performance Premium 1.4 TSI Decat Downpipe eliminates the restrictive factory catalytic converter assembly on the single-turbocharged EA111 engine platform (CAXA / CAXC). By replacing the highly restrictive OEM cast downpipe with a smooth, high-velocity mandrel-bent T304 stainless steel tract, exhaust gases exit your turbocharger with significantly reduced backpressure—providing the perfect baseline to support Stage 2 or Stage 3 ECU calibrations.

⚠️ CRITICAL COMPATIBILITY & WARRANTY NOTICE:
1) NO TWINCHARGER FITMENT: This product will absolutely NOT fit the 1.4 TSI Twincharged (supercharged and turbocharged) engines (engine codes CAVD, CTHE, etc., typically rated at 140bhp, 150bhp, 160bhp, or 180bhp). It is also NOT compatible with PQ25 chassis models like the VW Polo or Seat Ibiza.

⚙️ Core Product Features & Exhaust Dynamics

• Optimized Single-Turbo Spool: By stripping away the dense factory catalyst cell, backpressure directly behind the hot side of the turbocharger is slashed. This lets the CAXA/CAXC turbine spin up much faster, delivering improved throttle pick-up and mid-range torque.
• Deep, Polished Sound Profile: Promotes a sharp, sporty exhaust character under load without introducing unpleasant cabin drone or harsh metallic vibrations at regular cruising speeds.
