Best Exhaust Guide for RAM 1500
If you own a RAM 1500 you already know it's not just a Ute it's a statement. Whether you're hauling gear across the outback, towing a trailer up a mountain pass or just cruising the highway the RAM 1500 is built to work hard and look good doing it. But if you've ever thought your truck sounds a little too quiet for what it's capable of you're not alone.
A quality aftermarket exhaust system is one of the best upgrades you can make. It unlocks more of your engine's potential, gives you that deep authoritative exhaust note. At Outback Exhausts we've engineered cat-back system specifically for the RAM 1500 lineup and in this guide we'll walk you through everything you need to know to choose the right one for your build.
Why Upgrade Your RAM 1500 Exhaust?
The factory exhaust on the RAM 1500 is designed to be a compromise quiet, cost-effective and broadly compliant across multiple markets. That means it leaves a lot on the table. Here's what a quality aftermarket cat-back system actually delivers:
- Improved exhaust flow — mandrel bent stainless steel tubing eliminates the restrictive crush bends found in OEM systems letting your engine breathe properly.
- Better throttle response — less back pressure means your engine doesn't have to work as hard to push exhaust gases out which translates to a more responsive drive.
- A proper exhaust note — deep, aggressive and refined. Not a tinny rasp not a drone just the sound a V8 (or a Hurricane I6) deserves.
- Durability — our systems are built from 409 stainless steel with a 5year warranty so you're not replacing it every few years.
Which RAM 1500 Do You Have?
The RAM 1500 has gone through a few significant generations in Australia and the exhaust system that fits one won't necessarily fit another. Before you buy it's important to identify your variant. Here's a quick breakdown:
- RAM 1500 DS (2018–2021) — The first generation RAM sold officially in Australia through RAM Trucks Australia. Powered by the 5.7L HEMI V8.
- RAM 1500 DT (2018–2023) — The updated fifth generation RAM with a revised body and interior. Also powered by the 5.7L HEMI V8 but with a different chassis and exhaust routing.
Getting the right fit matters. Our systems are engineered as direct bolt-on replacements for each specific variant, so there's no cutting, welding, or guesswork involved.

What Is a Cat-Back Exhaust System?
If you're new to exhaust upgrades "cat-back" simply means the system replaces everything from the catalytic converter backwards the mid pipe, muffler and tip. It's the most popular type of exhaust upgrade because it delivers real performance and sound improvements without touching the emissions critical front section of the exhaust. That means it's straightforward to install and is reversible if you ever need to return to stock.
DS vs DT — What's the Difference?
This is one of the most common questions we get. The DS and DT are both 5.7L HEMI V8 trucks but they're different generations with different underbody layouts. The DS (2018–2021) was the first generation RAM sold through the official Australian network. The DT (2018–2023) is the updated fifth generation model with a revised chassis, interior and exhaust routing. The two systems are not interchangeable always confirm your build date and variant before ordering.

Installation: What to Expect
Our cat back systems are designed as direct bolt on replacements. A competent home mechanic with a basic set of tools can typically complete the install in 1–2 hours. If you'd prefer a professional fit any exhaust shop or 4x4 specialist can handle it. We recommend having the system fitted on a hoist for easier access to the underside mounting points.
Frequently Asked Questions
Will a cat-back exhaust void my RAM 1500 warranty?
No. A cat-back system doesn't touch the emissions critical front section of the exhaust. Under Australian Consumer Law a manufacturer cannot void your warranty simply because you've fitted an aftermarket exhaust provided the part hasn't caused the fault being claimed.
How do I know if I have a DS or DT RAM 1500?
Check your build date and compliance plate. DS models were the first generation RAM sold through the official Australian network (2018–2021). DT models are the updated fifth generation with a revised chassis and exhaust routing (2018–2023). The two systems are not interchangeable always confirm your variant before ordering.
Can I install the cat back exhaust myself?
Yes. Our systems are direct bolt on replacements requiring no cutting or welding. A competent home mechanic with basic tools can typically complete the install in 1–2 hours. We recommend using a hoist for easier access to the underside mounting points.
What material are the exhaust systems made from?
All our RAM 1500 cat back systems are built from 409 stainless steel with mandrel bends and a black polished tip finish. Every system is backed by a 5year warranty.
Does the RAM 1500 Hurricane I6 benefit from an aftermarket exhaust?
Yes. Turbocharged engines benefit significantly from improved exhaust flow. Our Hurricane specific cat back delivers better throttle response, reduced back pressure and a more refined exhaust note that complements the twin turbo I6's character.
