Description
The complete, dyno-proven exhaust for your Ram 1500 5.7L HEMI (2012–2023). The longest Tri-Y headers available for the Ram 1500, an integrated X-pipe centre muffler and a race crossover merge — in full polished 304 stainless steel. Big mid-range torque, sharper throttle response, and a deep V8 note you control: Quiet, Medium or Loud.
No cutting, no welding
Polished. No rust, no coatings
Torque & power across the range
Quiet, Medium or Loud
Engineered For Power — Not Just Noise
Longest Tri-Y headers available for the Ram 1500. The Tri-Y layout delivers massive mid-range torque — right where a 2.5-tonne truck needs it — while keeping the hard-charging top end of a 4-into-1 design.
Double-stepped primaries (1¾" → 1⅞") maintain exhaust velocity and enhance scavenging, producing strong torque and horsepower gains across the entire rev range — developed using the same design principles proven in V8 Supercars and NASCAR.
Integrated X-Pipe Centre Muffler
The X-pipe balances exhaust pulses between banks, improving flow efficiency and killing highway drone — while the race crossover merge sharpens throttle response. The result is a smoother, deeper, more aggressive HEMI note that sounds as serious as it performs.

Fitment & Install
Direct bolt-on header-back package — no cutting, no welding. We recommend installation by your local exhaust shop, though it can be fitted at home with a hoist and mechanical knowledge.
Tuning note: the system bolts on and drives as supplied, but a check-engine light will appear without a tune. A tune clears it and maximises the available gains.
Built To Last
Full high-grade polished stainless steel construction throughout — no rust, no coatings, no compromises. Designed, developed and dyno-tested by the team at GM Motorsport / Ramjet Performance, whose engine packages have powered championship-winning race programs.

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.
