Engineered for Power
Tri-Y header design — the longest Tri-Y system available for the Ram 1500, delivering massive mid-range torque while retaining the hard-charging top-end of a 4-1 design. Double-stepped primaries step from 1¾" to 1⅞" to maintain exhaust velocity, enhance scavenging and produce strong torque and horsepower gains across the entire rev range. The integrated X-pipe centre muffler balances exhaust pulses, improves flow efficiency, reduces drone and creates a smoother, more aggressive note, while the race crossover merge refines pulse balance for sharper throttle response.
Tune the Sound to Your Style
Interchangeable sound sections let you choose Quiet, Medium or Loud configurations to suit daily driving, towing or full race aggression — all without compromising performance.
Built to Last
Full high-grade polished stainless steel construction throughout — no rust, no coatings, no compromises. Developed using the same design principles proven in V8 Supercars and NASCAR, the Ramjet system delivers faster throttle response, stronger low- and mid-range torque, improved engine efficiency and a deep, aggressive exhaust note that sounds as serious as it performs.

Product information
PRODUCT FEATURES
Race Tri-Y Design
Our Tri-Y headers transform your Dodge Ram’s 5.7L, unlocking the torque and acceleration it’s been missing.
Because Aussie-delivered 1500s run the smaller 5.7L instead of the 6.2L Chevy, Ramjet engineered a system to close that performance gap. The result? The longest Tri-Y design on the market—carefully stepped, dyno-tested, and proven to deliver real-world gains.
With extra-long primaries rivaling some 4-1 setups, our system gives you the screaming top-end of a 4-1 with the fat mid-range punch of a traditional Tri-Y.
This isn’t just theory—it’s the same design philosophy used in V8 Supercars and NASCAR. Now you can bolt it onto your Ram for maximum torque, horsepower, and throttle response

RAMJET
Ramjet X-Pipe Centre Muffler
Featuring a true internal X-pipe, this centre muffler balances exhaust pulses for smoother flow, reduced drone, and a deeper, cleaner tone. Built from premium stainless steel to improve throttle response and mid-range performance without sacrificing comfort
Ramjet Race Crossover Merge
Our system is equipped with a precision-engineered race crossover merge designed to optimize both sound and performance.
By balancing exhaust pulses between banks, it reduces cabin drone while improving scavenging — drawing more exhaust flow from the next cylinder.
The result? Cleaner airflow, stronger torque, and increased horsepower across the rev range.
This isn’t just about noise control — it’s about unlocking maximum efficiency and race-proven power
Double Stepped Primaries
Our Ramjet exhaust features the famous stepped primary lengths, engineered for maximum efficiency and performance.
Starting at 1 3/4" off the head and stepping up to 1 7/8" further down the pipe, this progressive design accelerates exhaust velocity while simultaneously reducing back pressure.
The result is a system that not only flows better but also delivers a stronger scavenging effect, pulling exhaust gases out more efficiently and drawing in more fresh air-fuel mixture.More velocity means more flow, and more flow = more power!
Combined with our precision welds and premium stainless-steel construction, the Ramjet Ram isn’t just about performance gains—it’s about durability, sound, and that aggressive edge your build deserves.
F.A.Q.
They appreciate cut and details, things that aren't so obvious.
Which RAM 1500 variants does this suit?
Suits all Australian-delivered RAM 1500 DS & DT models with standard wheelbase. Does not suit Crew Cab Long Bed (153.5” wheelbase) models.
Who Can Fit The Exhaust?
The Ramjet Full Exhaust System is recommended to be installed by your local exhaust shop.
However, if you have access to a hoist and mechanical knowledge, this exhaust can also be fitted at home.
What can I expect after fitting the exhaust?
You can expect a significant change in exhaust note that truly brings the 5.7L HEMI engine to life. You’ll also notice increased torque when you put your foot down, delivering a stronger and more responsive driving experience.
Don’t be surprised if you end up loving your RAM even more
Why Should I Purchase This Exhaust?
Sooner or later, your RAM’s factory exhaust system will become a problem. These 5.7L HEMI engines are well known for exhaust manifold failures, ticking noises, and restrictive factory flow that holds the truck back from what it should truly sound and feel like.
So when the time comes, why replace it with another weak factory setup?
Upgrade to a Ramjet Full Exhaust System and transform the way your RAM sounds, performs, and feels every time you drive it. More power, more torque, a deeper aggressive note, and a driving experience your truck deserved from factory.
