The Exhaust Systems Australia FORD-MUSTANG-FN-ECOBOOST-VAREX-VALVED-CAT-BACK is a valved cat-back exhaust listed to fit the FN-series Ford Mustang EcoBoost. It runs a bi-modal muffler with a Varex valve, so the note can shift between a quieter and a louder mode.
What does this cat-back system cover?
A cat-back replaces the exhaust from behind the catalytic converter to the tailpipe, leaving the factory cat and the turbo pipework ahead of it in place. On the FN Mustang EcoBoost — Ford's turbo four-cylinder Mustang — this is the rear-section upgrade rather than a turbo-back rebuild. The listing doesn't publish a pipe diameter or material, so those are details we'd confirm with you rather than state.
What does a Varex valved bi-modal muffler change?
The defining feature is the bi-modal, valved muffler. A Varex-style valve opens or closes a path through the muffler so the system runs a more restrained note with the valve shut and a louder one with it open, usually switchable from the cabin. On a turbo four it's a way to add exhaust character on demand without being loud all the time. No sound level is published, so we can't quote one.
Will it suit my Ford Mustang EcoBoost?
It's listed to fit the FN-series Ford Mustang EcoBoost. As a special-order item, send your exact year and trim through and we'll confirm the listing matches before ordering. We treat fitment as listed-to-fit rather than guaranteed, so the build check happens first.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this valved cat-back in-house in the Illawarra. As a rear-section system it bolts to the back of the factory exhaust and the valve control needs wiring in, so we check rear clearances and confirm the valve switches cleanly before sign-off. RRP is listed at $1,900 AUD; as a special order we'll confirm lead time when you book.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does this keep the EcoBoost's catalytic converter?
- Yes — it's a cat-back, so it only replaces the exhaust behind the catalytic converter. The factory cat stays in place.
- What does the Varex valve do?
- It's a bi-modal valved muffler: the valve opens for a louder note or closes for a quieter one. No specific sound level is published for this listing.
- Is it a stock item?
- No, it's a $1,900 AUD special-order item. Give our Illawarra workshop your exact FN Mustang EcoBoost build and we'll order it in and fit it.
