Proven power.Record-setting performance.

Ramjet currently holds the Australian record for the fastest full-weight, bolt-on-only Ford Mustang down the ¼ mile.

Why it works

  • Engineered headers & high-flow cats

    Equal-length primaries for correct pulse timing and cylinder scavenging, race-merge collectors and 100-cell high-flow cats. Optional upgrade to the Ramjet double-stepped headers.

  • Refined Mustang V8 sound

    A deep, aggressive yet refined V8 tone. Unlike overly loud or raspy systems, it delivers a clean, deep note without harsh rasp.

  • Race-merge collectors

    Sharper exhaust pulse control for improved mid-range and top-end power.

  • High-quality exhaust

    304 stainless steel construction with accurate fitment and a clean final appearance.

Frequently asked questions

Will this fit my Mustang GT?

Yes — it fits the Ford Mustang GT 5.0L Coyote V8 in both 2015–2017 and 2018–2023 model years. Select your year above.

Is this a complete exhaust system?

Yes. It is a full header-back package — headers, high-flow cats, connector pipes, centre pipes and rear mufflers.

Do I need a tune?

The system bolts straight on. To extract maximum power from the headers and high-flow cats, a tune is recommended but not required for fitment.

What power gains can I expect?

Gains depend on your engine build and tune. This is a dyno- and track-proven system that holds an Australian ¼-mile record for bolt-on-only Mustangs.

Is it road legal?

It uses high-flow catalytic converters to retain street usability. Emissions rules vary by state, so check your local requirements.
