Cat-Delete Downpipe

The Milltek Sport Large-Bore Downpipe is engineered to significantly enhance the performance and auditory characteristics of your Ford Fiesta MK7/7.5 ST 1.6. Fabricated from aerospace-grade type 304 non-magnetic stainless steel, this downpipe offers superior durability and resistance to discoloration compared to standard materials. Its larger diameter, 2.75 inches (69.85mm), allows for a greater volume of exhaust gases to exit the engine, leading to improved efficiency and potential power gains. This downpipe is specifically designed as a catalyst delete, meaning it removes the catalytic converter to further reduce exhaust gas restriction and maximize flow. Installation of this downpipe mandates that it be fitted in conjunction with a Milltek Sport Cat-Back system. Furthermore, a Stage 2 ECU remap is a mandatory requirement for proper operation and to safely utilize the increased exhaust flow. Due to the removal of the catalyst, this component is intended for track use only and will render the vehicle unable to pass a standard MOT test. Milltek Sport emphasizes that only EC type-approved components are legal for road use. The construction process involves mandrel bending to ensure consistent radius bends and optimized gasflow. Milltek's research and development team meticulously designs these systems in the UK, aiming for a sporty and crisp exhaust tone without inducing NVH (Noise, Vibration, and Harshness), drone, or cabin resonance. This commitment to quality ensures that while performance is increased, the driving experience remains refined.
