Description
Enhance your 1.8T 225 hp engine’s boost efficiency with the Forge Motorsport Alloy Boost Hard Pipe, a high-performance upgrade designed to replace the OEM resonated turbo outlet pipe found on select Audi and SEAT models. This precision-engineered hard pipe eliminates the factory turbo resonator, significantly improving airflow and reducing turbo lag.
Designed to fit seamlessly on vehicles such as the Audi TT 225 (8N), Audi S3 225 (8L chassis), and SEAT Leon Cupra R (Mk1, 1998–2005), this pipe runs along the left side of the engine and mounts using the original factory brackets for a hassle-free installation.
By removing the OEM sound resonator, the Forge hard pipe allows for uninterrupted boost flow, enhancing throttle response and allowing your turbocharger to spool faster. This not only improves drivability but also reduces the overall load on the turbo system, which can extend component longevity—particularly valuable for tuned or hard-driven vehicles.
A common design flaw in the OEM setup is the restrictive dent in the underside of the pipe to clear the camshaft cover. Forge addresses this with a carefully optimized clearance dent that maintains structural integrity and minimizes flow restriction—ensuring maximum performance without compromise.
