4 Most Cost-Effective Upgrades for 5.7 HEMI RAM
The 5.7 Hemi Ram 1500 has a number of performance improvements available. However, understanding the technical aspects of each component and what they accomplish may be daunting. If this is your first time upgrading your truck or if you just need a refresher, here’s a rundown of each one of these upgrades.
Let’s start upgrading your 5.7L RAM with the most cost-effective changes, which are:
Cat Back Exhaust Upgrades
Cold Air Intake Upgrades
Headers Upgrade
Custom Upgrades With a Tuner
Combined, these three changes will require a budget of $1000 to $2000 depending on the manufacturer’s choice.
We chose these upgrades because they show the most value for the least amount of money.
Second, they do not change the engine design but act as an upgrade or auxiliary to increase horsepower.
And they also require minimal skills and time to install on your 5.7L DODGE RAM.
Let’s take a look closer.
5.7 HEMI RAM Cat Back Exhaust Upgrades
A cat back exhaust is an exhaust system that sits behind the catalytic converter and, as a result, has the name. The intermediate pipe that connects to the catalyst converter, muffler, and exposed tailpipe on every 5.7 Hemi Ram 1500 is part of this exhaust system. These systems are usually installed in place of axle back exhausts, which are similar to cat backs but lack the intermediate pipe.
An exhaust system is a vehicle’s method of removing the harmful chemicals produced by its engine. It routes noxious gases out the back of the vehicle and, in addition, reduces noise levels. A muffler is part of the exhaust system, which dampens any sounds generated when idling, accelerating, or revving. Finally, an exhaust system improves both fuel efficiency and performance overall. Because a proper ratio of air and fuel is required for maximum engine performance, exhaust systems assist to remove exhaust gases more quickly so that they may be replaced with oxygen for improved or enhanced engine functioning.
Performance Cat Back Exhaust from different brands have some differences:
different levels of performance exterior sound (from soft bass to aggressive)
steel grade
different colors
different exit types

A cold air intake is an aftermarket component that draws cold air from the engine compartment or the exterior of the car and funnels it to the engine. There are two types of cold air intakes: traditional and short ram. A cold air intake, as the name implies, feeds colder air into the engine to increase performance. A short ram has a smaller diameter pipe in order to minimise restriction. Both have an identical impact on performance by increasing power and torque while also improving fuel efficiency.
Cold air intakes outperform the factory intake for the following reasons: Cold air is heavier and has greater oxygen content. This oxygen-rich air, which is richer in energy, provides better efficiency and a boost to the Hemi Ram 1500’s power when it fires.

The Air Charger 63-1561 item from K&N is a 63 series cold air intake for the Dodge Ram 1500. This air intake, like many others, offers excellent performance with better airflow and a bigger filter. The Air Charger enhances the amount of air that can pass through it by increasing the volume and employing a chrome-topped re-usable air filter and a heat shield. This prevents the airflow from becoming excessively hot, preventing it from affecting the air-fuel mix. The K&N filter is designed to last 100,000 miles before you should replace it under normal driving conditions, after which you may clean it and reinsert it into the intake. K&N's intake and the next one in our list were a tie for first and second place in our book. We appreciated K&N's emphasis on performance and how much it delivered, as well as the chrome filter. Their models provided the best value for your money when combined with their low prices.

Exhaust headers, also known as exhaust headers, are aftermarket components that replace the stock exhaust manifolds. The first component of the exhaust system is the exhaust manifold, which allows exhaust to travel between the engine cylinder heads and the front of the exhaust pipe.headers provide greater tube diameter than exhaust manifolds, allowing more fumes to escape from the system faster. In contrast to an exhaust manifold, which is generally made to fit a small space rather than with performance in mind, headers have larger tubes that allow for faster exiting of gases.
All vehicles, from the 5.7 Hemi Ram 1500 to trucks and SUVs, can benefit from headers. Because exhaust leaves the system more quickly, oxygen may enter it again. This leads to better fuel efficiency, torque, and performance as a result of improved airflow through the engine. Other advantages of headers include a throatier engine roar, less weight (because stainless steel exhaust manifold replacements eliminate cast iron versions), and perhaps improved engine longevity.
The Gibson performance header is one of the finest headers for your 5.7 Hemi Ram. Its stainless steel tube promotes increased power while also ensuring long-term durability. Gibson headers are designed to maximize the performance of your car. These headers are ideal for lowered or raised trucks and tow vehicles since the gains are built to occur at low and medium rpm on the highway. They have mandrel-bent primary pipe for more flow and easy installation. Installing Gibson headers will improve your car's horsepower and throttle response while also reducing its temperature. These headers are designed to fit the vehicle as it came from the factory. This covers elements like cylinder heads, chassis, steering, motor mounts, body mounts, and bushings. It is the job of the installer to ensure that the parts fit. Gibson headers come in a variety of sizes, configurations, materials, and finishes. Order the header model that is appropriate for your car. The Gibson Headers are a great header upgrade for your 5.7 Hemi RAM. With all of the necessary hardware included in the package and a direct factory fit, installation is much easier. The ease with which you can install it, as well as its effectiveness, make this header one of the best for a Hemi RAM.

The engine control system is modified by the Tuner module of the vehicle computer system. In a word, a tuner is an engine management system that controls the air/fuel mixtures fired through your engine. It also calculates a variety of variables such as as timing, idle speed, fuel pressure, and more. What this means for you is that by eliminating the factory installed equipment (which restricts power), you may safely and effectively unleash all of your car’s potential power.
After you’ve installed the tuner, it runs its own checks on your car’s computer via the ECU and makes improvements as a result.
The addition of a tuner to your 5.7 HEMI is arguably the most significant power improvement you can make. It’s not simply about the benefits of tuning the 345 Mopar engine. A tune is also essential for obtaining greater performance from additional modifications. When you start adding airflow and fuel, make sure to properly calibrate the computer (PCM) for all of the changes. A tune remains a great performance modification as a stand-alone upgrade for Dodge and Ram vehicles.
The road depends on what performance you wish to improve: whether it’s your gas mileage or all-out performance in the vehicle.
We’ll reveal some of the greatest tuning devices on the market, as well as their cutting-edge capabilities to match your Ram and unleash the beast in your truck in this post.
Final Thoughts
The 5.7 HEMI engine has a little underperformance when new, in our opinion. Even modest bolt-on modifications may help the 5.7L Mopar V8 reach excellent results. A tune is an excellent place to start if you want to create a foundation for making more power.
After a tune, we think headers and camshafts are the next best improvements. They may be rather costly if you choose premium grade components and do not DIY the work. A tune with headers and cams, on the other hand, may easily increase 30-70+ horsepower when everything has been said and done. 5.7 HEMI modifications, such as exhaust systems and intakes, can also provide a little more power at a reasonable price.
If you want more, there are Dodge/Ram 5.7L performance upgrades like throttle bodies, intake manifolds, and final drives that may help. If that isn’t enough, forced induction such as a supercharger may be an option. You can easily build a 500-700+hp 5.7 HEMI by going this route, but you’ll also be $20,000+ in the hole if you do so. Regardless of what path you take – whether it’s a few upgrades or complete overhaul – the 5.7 HEMI becomes a whole new beast with them eliminated.
