The XForce ES-FM19VMK-CBS is a Varex valved cat-back exhaust listed to fit the Ford Mustang FN EcoBoost. It runs a bi-modal valved muffler and replaces the pipework from the cat back, supplied by XForce and fitted at our Illawarra workshop.

What does this system cover?

As a cat-back, the ES-FM19VMK-CBS replaces the exhaust from the catalytic converter rearward, keeping the factory cat in place. The slug records it for the Mustang FN EcoBoost, and the record marks it as valved with a bi-modal muffler — XForce's Varex system. XForce does not publish the diameter or material for this listing, so we confirm those against the part at fitting.

What does a Varex valved, bi-modal cat-back change?

A bi-modal valved muffler has an internal valve that opens and closes to switch between two modes — a quieter setting and a louder one — so the Mustang can be civil at a cruise and more open on demand. On the FN EcoBoost it is a cat-back, so it changes the back half of the system and the note relative to stock while leaving the emissions hardware up front standard. We do not quote sound figures, as none are published; the record confirms it is valved and bi-modal.

Will it suit my Ford Mustang?

It is listed to fit the Ford Mustang FN EcoBoost. That model and engine line are recorded in the listing, but the supplier does not break out the full sub-variant detail, so confirm your exact build with the workshop before ordering. Fitment feed data can be imperfect.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits XForce Varex valved cat-backs like the ES-FM19VMK-CBS in-house across the Illawarra. We check it against your Mustang's hangers, fit the valved muffler and pipework to sit square, seal each join, and confirm the valve control is working. It is listed to fit the FN EcoBoost Mustang; send your build and we will confirm it first. The recommended retail price is $1,900.
