Bull-X 3″ downpipe, Ford Focus RS Mk3
A downpipe is one of the most popular upgrades for a turbocharged engine. Efficient exhaust flow is important for a turbo system, and a freer-flowing pipe can provide a sportier sound while improving throttle response and power potential.

This product does not have model-specific ECE approval. It is intended for motorsport and other off-road enthusiast use. Always check the current road regulations before installation.
Bull-X 3″ downpipe, Ford Focus RS Mk3 is a vehicle-specific stainless-steel assembly for Ford Focus Mk3 RS 2.3 EcoBoost. Its 76 mm / 3″ pipe size and freer-flowing design reduce exhaust back pressure and allow the turbocharger to operate with less restriction, particularly on tuned engines.
Lower back pressure can improve turbo response and throttle response while reducing thermal load on the exhaust side. The vehicle-specific design replaces the original component without unnecessary fabrication.
