Along with sounding awesome, exhaust upgrade benefits include improved performance and fuel economy. For over 2 decades, I’ve helped thousands of 4×4 enthusiasts enjoy the benefits of upgrading their stock exhaust system.
Have you been wondering, “Are exhaust upgrades worth it?”. This article will show you why replacing some of your stock exhaust system can result in significant performance gains, better sound, and improved fuel economy.
Top 4 Exhaust Upgrade Benefits
- Distinct, Sought-After, Sporty Acoustics
- Better Performance
- Improved Fuel Economy
- Improved Visual Appeal
1. Awesome Acoustics
We’ll start with a popular reason for exhaust upgrade: That distinct, aggressive, rumbling sound.
Sporty exhaust notes are highly sought after amongst 4×4 enthusiasts. We can tailor an exhaust upgrade to give you the exact sound you’re looking for.
2. Better Performance
Stock exhaust systems are designed for the masses. They are also manufactured to be emissions-friendly and quiet, often featuring smaller diameter, lower-quality piping.
An aftermarket exhaust removes these restrictions, improving efficiency and enabling better air flow. By increasing efficiency and air circulation, many 4×4 owners notice a significant improvement in power and torque after an exhaust upgrade.
| Stock Exhaust | Exhaust Upgrade |
|---|---|
| Limited by manufacturing standards | Remove restrictions to unlock performance potential, including better torque, power, and fuel economy |
| Generic, standardised, lower-quality parts | Higher quality parts that look and perform better |
| Mass-produced, zero personalisation | Various customisation options, from sound to appearance |
| Restricted air flow, reduced efficiency | Better airflow, reduced back pressure, better engine performance |
3. Improved Fuel Economy
Here’s a less realised benefit of an exhaust upgrade: improved fuel economy.
Higher power and better fuel economy don’t sound like they should go together, but an exhaust upgrade can make it happen.
An upgraded exhaust system decreases restriction and increases air circulation in the engine. This boosts efficiency and reduces dirty air due to poor circulation in the engine.
By making it easier for exhaust gasses to be cleared, fuel consumption is reduced. A more efficient exhaust system almost always results in better fuel mileage.
4. Improved Visual Appeal
Along with improved fuel efficiency and higher horsepower, an exhaust upgrade can enhance your 4×4’s visual appeal. A stylish exhaust upgrade can add an elevated style that makes your 4×4 stand out from the rest.
If you’re tired of staring at a rusty stock pipe, swap it out for an eye-catching, shiny, stainless-steel system.
Are Exhaust Upgrades Worth It?
Are exhaust upgrades worth it? I would say that yes, they generally are. But there are some considerations I like to make customers aware of.
Deciding if an exhaust upgrade is worth it for your 4×4 mostly comes down to personal preference. I find it most helpful for customers to have realistic expectations of what an exhaust upgrade will offer.
If you answer ‘Yes’ to all of these questions, an exhaust upgrade is likely worth considering for your 4×4:
- Do I want better exhaust notes with more volume and a distinct sound?
- Do I want more longevity from my exhaust system?
- Do I want better fuel economy?
- Do I want my exhaust system to stand out and have better visual appeal?
If performance is all you are after, you may want to consider a different upgrade option. You may also prefer a different upgrade if you dislike cabin drone.
For the ultimate performance gains, I recommend an exhaust upgrade combined with ECU Remapping or Dyno Tuning.
How Much Does a Performance Exhaust Cost?
The exact cost of an exhaust upgrade will depend on your requirements and goals. I tell customers to expect an exhaust upgrade to start around $1500, depending on your specifications.
Factors Affecting the Cost of An Exhaust Upgrade
Here are the main factors that affect how much an exhaust upgrade costs:
- Exhaust System Type: Custom and high-end systems cost more.
- Material Quality: Stainless steel is pricier but more durable and rust-resistant.
- Installation: Complexity and additional modifications (i.e., cutting and welding) increase costs.
- Performance Enhancements: Increased horsepower and optimized exhaust flow raise costs.
- Sound Design: Want a certain sport note or particular sound? Custom exhaust notes add to the price.
- Vehicle Make & Model: Unique or high-end models cost more.
- Part Costs: Extras such as high-efficiency catalytic converters and oxygen sensors ($20–$100) add expenses.
Things to Consider Before You Upgrade
I recommend these considerations to ensure your exhaust upgrade meets your needs:
- Exhaust Type: If performance gains are your main priority, I recommend a cat-back exhaust. Cat-back exhaust upgrades offer a great horsepower boost, and they are generally legal.
Cat-back exhaust upgrades can give a power boost that is legally compliant with Australia’s emission and noise regulations. Learn more about the different types of exhaust upgrades in my guide here: Do Aftermarket Exhausts Improve Performance Significantly?
- Compatibility: Ensure your desired exhaust upgrade is compatible with your 4×4’s make, model, and year.
- Exhaust Pipe Thickness: For off-roading enthusiasts, I prefer a thicker, higher-quality exhaust pipe. A thicker pipe is far better at handling temperature swings and off-road terrain. The key is finding the balance between a durable, proportionally sized exhaust pipe versus an undersized or oversized pipe.
Exhaust pipe thickness also plays a big role in the sound of your exhaust. A thinner pipe creates a higher-pitched, tinny sound. For that beefy, aggressive exhaust note, you’ll want a thicker pipe.
- Quality: For maximum durability and longevity, I recommend a stainless steel exhaust system. The underside of your vehicle is subjected to heat, moisture, rough terrain, vibrations, and other extreme conditions. A high-quality steel will help guard your exhaust against damage and maximise longevity.
- Legal Ramifications: Double check that any exhaust upgrades you choose are compliant with local regulations. For instance, if you run a pre-DPF/turbo back exhaust, your 4×4 is required to have a catalytic converter.
- Warranty: I always emphasise the importance of double-checking if and how an exhaust upgrade will affect your vehicle’s warranty.
