The worlds best performing RAM exhaust system
Unlock the power of your dodge ram today!
World Class Dyno Facility
Phonsy, with his state-of-the-art mainline dyno, has tested many prototypes for the REX exhaust system. Perfecting the system, with the goal to improve all aspects of the car. Including drivability, throttle response, increased power, better fuel economy and of course. An amazing sound.
Ramjet Dyno Results
Struggling to find the perfect exhaust system for your RAM? Can't find an exhaust system that can improve all aspects of your driving experience?
We have been in the game for well over 25 years. With all the experts in the industry helping to design this exhaust system. You will not be disappointed!
WHY OUR SYSTEMS ARE BETTER
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 X-Pipe Centre Muffler
Engineered for enthusiasts who demand performance and refinement, the Ramjet X-Pipe Centre Muffler is designed to optimise exhaust flow while delivering a deep, aggressive tone without unwanted drone.
At the heart of the muffler is a true X-pipe crossover, merging exhaust pulses from both banks to improve scavenging, smooth airflow, and balance pressure across the system. The result is sharper throttle response, stronger mid-range torque, and a cleaner, more controlled exhaust note.

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.
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.
Full Stainless Steel Construction
Our systems come fully polished and stainless for longevity and health of our exhausts.
Some systems are built with a low grade stainless, that require painting to prevent rusting. This painting is toxic. Especially when fitted to your car. the paint reacts with the heat causing fumes that are unhealthy for the occupants.
Most dyno operators refuse to even operate these painted systems on the dyno fearing longterm effects.
Our system is made from high quality polished stainless steel that looks good and is durable. No need to worry about paint fumes and repainting all rust.
