Unlock Hidden Power | Piper 3" Sports Cat Downpipe for Fiesta ST180
The first major restriction in your Fiesta ST180's exhaust isn't the muffler it's the factory downpipe. OC Motorsport presents the Piper 3" Sports Cat Downpipe, the definitive catalyst for unleashing significant power gains, sharper throttle response, and a truly aggressive exhaust note from your turbocharged engine.
Engineered for performance, this downpipe replaces the restrictive OEM unit with a high-flow 200-cell sports catalyst and massive 3" (76.2mm) stainless steel tubing. This critical upgrade dramatically reduces backpressure, allowing your turbo to spool faster and your engine to breathe more efficiently, paving the way for major gains when paired with a custom remap.
Engineered for Maximum Performance:
Significant Power & Torque Gains: By eliminating the primary exhaust restriction, this downpipe is one of the most effective bolt-on mods for releasing hidden power, especially when tuned.
Faster Turbo Spool: The reduced backpressure allows the turbocharger to spin up more quickly, drastically improving throttle response and reducing lag.
High-Flow 200-Cell Sports Cat: Strikes the perfect balance between massive flow gains for power and environmental consideration, with a deep, race-inspired tone.
Mandatory for Stage 2+ Tunes: This is an essential foundation upgrade for anyone pursuing serious power targets and a full performance exhaust system.
Premium UK Construction: Hand-built from T304 stainless steel for a lifetime of durability and backed by Piper's renowned lifetime guarantee.
