Product description:
The EC/ECE-approved 4" (101.6 mm) downpipe from HPerformance was developed specifically for the 2.5 TFSI DAZA engines and combines flow-optimized design with OEM-like integration and unrestricted suitability for everyday use.
At the heart of the design is a fully flow-optimized geometry, starting directly at the turbocharger outlet. A precisely designed inlet ensures a clean, low-loss transfer of exhaust gases from the turbine housing into the 4-inch cross-section.
Further along, the continuous pipe routing ensures stable flow without abrupt changes in cross-section. The integrated 160 mm ceramic catalytic converter with built-in thermal insulation is optimally integrated from a flow dynamics perspective and designed for high efficiency in a production environment.
A specially tuned outlet behind the catalytic converter supports the uniform expansion of the exhaust gases and contributes to a further reduction in flow losses and backpressure. This overall design reduces exhaust backpressure and improves the system’s thermal behavior, which has a positive effect on efficiency and responsiveness.
An additional effect of the enlarged, evenly guided pipe geometry is a significantly altered sound character: The 2.5 TFSI develops a deeper, more powerful, and fuller sound without sounding unpleasant or intrusive. The downpipe meets the requirements of the EC/ECE regulation and is therefore legal for use on public roads.
No engine control unit (ECU) tuning is required. Typical HPerformance: Development focused on reproducible results, technical precision, and durable components—designed for demanding road use. Drivable without software tuning: This EC/ECE-approved downpipe can be installed without any modifications to the engine control unit.
