Forge Motorsport High-Flow K04 Turbo Outlet Muffler Delete Pipe

Improve throttle response and enhance under-bonnet acoustics on your high-performance engine with the premium Forge Motorsport turbo outlet muffler delete pipe. Carefully engineered for the classic belt-driven Volkswagen Audi Group 2.0 petrol turbo (TFSI) EA113 engine configurations equipped with the larger factory K04 turbocharger, this hardware upgrade fixes a significant factory restriction. The original equipment manufacturer (OEM) part features multiple internal openings and slots designed to generate air turbulence and muffle turbo spooling acoustics. While effective for noise reduction, this stock design creates air restriction at the turbo outlet, slowing down pressure delivery and reducing transient throttle response.

Precision Billet Engineering & Three-Point Contact Profile

To eliminate this significant factory bottleneck, the engineering team at Forge Motorsport developed a single-piece, smooth-bore replacement pipe. Precision-machined in the UK from high-grade 6061-T6 aircraft aluminum billet, this component features an advanced three-point contact design that completely eliminates any risk of internal structural resonation. The delete pipe drops down smoothly from an internal diameter of 2.5 inches where it joins the turbo housing, tapering cleanly down to 2 inches at the intercooler coupler hose end. This geometry smooths out the airflow path, allowing compressed air to exit the housing efficiently for faster turbo spool-up.

Complete Upgraded Fluid Routing Kit Components

Unlike lower-quality copies that only include the machined aluminum pipe, this premium performance modification comes supplied as a complete hardware bundle. The kit features a high-temperature, oil-resistant Fluorosilicone-lined silicone connection hose alongside matching high-end worm-drive hose clamps. This structural silicone layer provides absolute chemical immunity against hot oil mist, ensuring an airtight connection under extreme working boost pressures.
