The CTS Turbo Top Mount Exhaust Manifold is engineered for transversely mounted VW/Audi 1.8T 20V engines. This manifold features a T3 turbocharger flange and is designed to work with 38mm or 39mm external wastegates. Its top-mount design facilitates straightforward installation. The semi-equal length runner configuration is employed to balance optimal peak power output with responsive spool characteristics, making it a versatile upgrade for performance-oriented 1.8T applications. Constructed from high-grade ductile iron, this manifold offers superior durability and resistance to extreme heat, cracking, and warping. This robust material choice ensures longevity and reliable performance under demanding conditions. The precision casting and design are intended to provide a direct fit for various VW and Audi models, including MK4, MK3, MK2, Audi TT225, TT180HP, S3, and compatible Seat and Skoda 1.8T variants. Specific fitment details should always be confirmed with the vehicle's exact year, model, and engine configuration.
