Forge Motorsport Enlarged Turbo Discharge Pipe Upgrade for VAG 2.0 TSI (EA888 Gen 4 EVO4 Engine)

With the incredible tuning popularity of the latest generation VAG 2.0-litre petrol turbo powerplants, extracting reliable power requires eliminating restrictions within the forced induction system. The original equipment discharge pipe system features narrow paths and flexible rubber routing that expands under heavy boost pressure, creating severe turbulence. The engineering team at Forge Motorsport used state-of-the-art 3D scanning equipment and advanced CAD simulation tools to create the FMDP1 kit—a high-flow replacement designed to maximize boost volume and deliver smoother airflow.

Key Engineering Features

• Mandrel-Bent Alloy Hardpipe: Constructed from high-strength mandrel-bent aluminum tubing with an expanded internal diameter to optimize flow capacity.
• 4-Ply Fluoro-Lined Silicone Hoses: Heavy-duty multi-layer silicone hose links feature an interior coating that prevents breakdown from oil mist or heat.
• Billet Structural Mounting Bracket: Supplied with an in-house CNC machined billet mounting bracket to secure the assembly under intense engine movement.
• Proven Performance Gains: Real-world dyno verification shows typical gains of 3 to 5 BHP alongside 5 to 7 NM of torque, depending on your software tuning stage.
• OEM+ Visual Presentation: Finished in a resilient stealth textured black powder coat, matching your factory engine bay aesthetics perfectly.

System Performance & Fluid Engineering

This premium performance hardpipe kit replaces the weak factory part, ensuring it easily holds higher boost pressures without expanding or developing boost leaks over time. By increasing structural durability and widening the internal diameter from the turbocharger compressor exit to the charge system layout, it provides a highly reliable modification for stage 1 and stage 2 tuned hot hatches. This generic kit includes all necessary hose colors matching a stealth black appearance profile.
