What to Consider When Upgrading Your Holden Colorado Exhaust

If you own a Holden Colorado, you’re likely no stranger to the vehicle’s blend of practicality, power, and rugged charm. Whether it’s for work, weekend getaways, or towing heavy loads, the Colorado is a versatile ute that handles it all. But like many enthusiasts, you may be looking to unlock even more performance from your Colorado, and one of the best ways to do this is by upgrading the exhaust system.

An aftermarket exhaust isn’t just about enhancing the sound of your ute – though that’s definitely a perk. It can also improve performance, boost fuel efficiency, and even extend the life of your engine. With so many options available, it’s important to know what factors to consider when choosing the best exhaust system for your Holden Colorado. Here’s what you need to think about before making the leap.

Material Choices: Stainless Steel vs. Aluminised Steel

When it comes to Holden Colorado exhaust systems, the material they’re made from matters. The two main materials you’ll find are stainless steel and aluminised steel. Each has its pros and cons depending on what you want from your exhaust.

• Stainless Steel: Stainless steel exhausts are incredibly durable and resistant to rust. This makes them a top choice for drivers who frequently expose their ute to harsh environments, whether that’s through off-roading, coastal driving, or long-term use. A stainless steel exhaust is more likely to last longer and hold up under tough conditions. While it may come with a higher price tag, it’s generally a long-term investment.
• Aluminised Steel: Aluminised steel exhausts are more affordable but slightly less durable when compared to stainless steel. They offer a good balance between cost and performance. That being said, for most Holden Colorado drivers, they’re more than adequate for daily use and light off-roading. However, if you drive in particularly wet or humid environments, you may find that an aluminised steel system shows signs of rust faster than stainless steel.

Performance Gains: Unlocking More Power

One of the main reasons people upgrade their exhaust system is to boost the performance of their Holden Colorado. Stock exhaust systems can sometimes restrict airflow, which limits the engine’s potential to produce more power. Aftermarket exhausts, on the other hand, are designed to improve the vehicle’s exhaust flow.

Upgrading to a high-performance exhaust system can result in noticeable gains in horsepower and torque. The improved flow of exhaust gases reduces back pressure, allowing your engine to breathe more easily. This translates into better overall engine efficiency and performance, especially when towing or driving under heavy loads.

Fuel Efficiency: Is It Worth It?

Another major consideration when upgrading your exhaust is the potential for improved fuel efficiency. While it may not seem like an exhaust system would have much to do with your fuel consumption, the two are actually closely linked. A more efficient exhaust system helps the engine run smoother, meaning it doesn’t have to work as hard to push out exhaust gases.

The result? You may find yourself making fewer stops at the petrol station. However, the gains in fuel efficiency are typically modest. The real value comes from a combination of better performance, smoother driving, and perhaps a little extra savings on fuel over time.

Exhaust Sound: How Loud Do You Want to Go?

For many drivers, the sound of an upgraded exhaust system is just as important as the performance benefits. Depending on the design, an aftermarket exhaust can give your Holden Colorado a deeper, throatier roar, especially when accelerating. But before you decide to crank up the volume, consider how much noise you actually want.

• Mild Sound: If you use your Colorado primarily for daily driving, you might prefer a more subtle upgrade. Many performance exhausts offer enhanced sound without being overly aggressive, giving your ute a satisfying growl without waking up the entire neighborhood.
• Aggressive Sound: On the other hand, if you’re looking for a head-turning rumble that makes a statement, there are exhausts designed to amplify the sound significantly. Just be mindful of noise restrictions in your area. A loud exhaust might be fun on the open road, but it could become a hassle in residential areas or urban environments.

Single vs. Dual Exhaust: Which is Right for You?

When upgrading your exhaust, you’ll also need to decide between a single exhaust system and a dual exhaust system.

• Single Exhaust: A single exhaust system is typically more affordable and easier to install. It’s more than sufficient for most drivers and offers performance improvements without going overboard. If you’re simply looking to boost your ute’s power and fuel efficiency, a single exhaust will do the job.
• Dual Exhaust: A dual exhaust system, on the other hand, gives your Holden Colorado a sportier look and can offer slightly better performance gains, especially in terms of engine airflow. While it tends to be more expensive and complex to install, it’s a great option for drivers looking for both aesthetic and performance enhancements. The dual pipes can also produce a more aggressive exhaust note, which is a big draw for many ute enthusiasts.

Legal and Environmental Considerations

Before upgrading your exhaust, it’s important to check local regulations. In some areas, there are limits on how loud your vehicle can be, and installing an overly aggressive exhaust system could get you in trouble with noise ordinances. Additionally, certain exhaust upgrades may impact your vehicle’s emissions, so make sure the system you choose complies with Australian environmental standards.

Many aftermarket exhaust systems are designed to be emission-compliant, but it’s always a good idea to double-check before making your purchase. Look for systems that meet or exceed the necessary emission standards to avoid any legal headaches down the line.

Cost and Installation: What to Expect

As with any vehicle modification, cost is always a factor. Exhaust systems can range from a few hundred dollars to well over a thousand, depending on the material, brand, and design. Stainless steel systems, for example, are generally more expensive than their aluminised steel counterparts. Dual exhaust systems will also likely cost more than single systems.

You should also factor in installation costs. While some enthusiasts may opt for a DIY installation, many exhaust systems require professional installation, especially if they involve custom fittings or additional parts like catalytic converters or resonators.

Final Thoughts

Upgrading the exhaust system on your Holden Colorado can enhance the driving experience in several ways—from boosting performance and improving fuel efficiency to giving your ute a more powerful sound. However, it’s important to weigh up your options carefully before making a decision. Material choice, sound levels, legal requirements, and, of course, your budget, should all be taken into account.

Whether you’re looking for a subtle performance boost or a more noticeable upgrade, there’s an exhaust system out there that’s perfect for your Holden Colorado. Do your research, consider your needs, and invest in an exhaust that will make your ute perform and sound better for years to come.
