Fi EXHAUST - Ford Focus ST MK4 / MK4.5 OPF - OPF front pipe, mid-pipe, valved muffler, dual silver tips and remote

This Fi EXHAUST application is for Ford Focus ST MK4/MK4.5 cars with the 2.3 EcoBoost engine and OPF. The listed package includes the OPF front pipe, mid-pipe, valved muffler, two silver tips and standard remote module, separating it from non-OPF applications and standalone downpipes.

The primary system code FD-STMK4F-CBE is accompanied by TIP63127S*2, ACT-BN, R2016OL and OBD-CAB-5BNE. Check the bundle as a whole: the 2.3 EcoBoost engine alone does not confirm OPF fitment or the correct hatchback/wagon body configuration.

Valves and sound

The valved muffler lets the driver switch between a more restrained delivery and a more open sport tone. This package lists a standard remote rather than relying only on a factory button. Sound will also depend on OPF condition, other exhaust modifications and correct installation on the specific Focus ST.

This SKU explicitly lists a standard remote module. Check that the control box, cable and valve operation match this configuration; do not substitute Fi Pro without a separate fitment check.

Fitment

Listed application: Ford Focus ST MK4 / MK4.5 OPF, 2019+; Chassis MK4 / MK4.5; 2.3T EcoBoost engine; OPF equipped. These details matter more than a similar model name: a generation, engine or filter change may require another part number. Confirm factory specification by VIN before pre-ordering.

Before ordering, confirm MK4 or MK4.5, hatchback or wagon body, model year, 2.3 EcoBoost and OPF. A different filter or body revision may require another code. A downpipe and other optional parts are not included unless they appear in the package SKU.
