Why equal-lengthheaders?
Each cylinder’s exhaust travels the same distance before reaching the collector, keeping pulses evenly spaced. That balance improves scavenging, reduces backpressure and gives a cleaner, sharper note.
Why it works
1¾″ primary
Designed for maximum torque and throttle response.
Equal-length pipes
Carefully shaped primary tubes create near-perfect equal lengths for optimal scavenging.
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.

What Mustang owners say

Love the new sound these headers produce. I was not sure on what was needed to fit up to my existing 3" system, so I rang GM Motorsport and the gentleman could not of been more helpful and answered all my questions. If your going to purchase a set of headers for your car, do yourself a big favour and buy them from GM Motorsport. You won't be disappointed. Thank you for all your help, cheers David.

Mustang GT 1¾″ Headers & Cats I hadn’t heard of Ramjet Exhausts before, but decided to give them a shot and I’m glad I did. The quality is unreal, the sound is exactly what I was chasing, and the power gains were instantly noticeable. Couldn’t be happier with the setup.

Sounds unlike any other system Ive heard!

Frequently asked questions
Will these fit my Mustang? +
They bolt onto the Ford Mustang GT 5.0L Coyote V8 from 2015–2023. They do not fit the S650 (2024+).
1¾″ vs the double-step headers — which should I choose? +
The 1¾″ is an excellent all-round choice for NA and forced-induction builds. Step up to the double-stepped 1¾″→1⅞″ headers if you’re chasing maximum flow on a high-horsepower build.
Metal or ceramic cats? +
100-cell metal suits most naturally aspirated builds; 200-cell ceramic is recommended for forced-induction engines.
Do I need a tune? +
Recommended to realise the full gains, but not required for fitment.
Who can install the exhaust? +
For the best results, we recommend having the exhaust fitted by a professional exhaust or performance workshop.
