But you also know that like most pickup trucks, the Silverado isn't exactly built for enhanced performance. You can't blame Chevy for those lackluster stock parts – but you can do something about it with some Silverado performance upgrades. Whether you're hoping your truck becomes a dragstrip legend, or you just have that itch for more power and performance, we're giving you the inside scoop on the five best performance upgrades for 5.3 and 6.2 Silverado trucks.

1. Unleash True Horsepower With a Performance Exhaust

An aftermarket exhaust system is one of the most common (and loved) Silverado performance upgrades you should consider picking up. Aftermarket Silverado exhausts don't just sound awesome; they're also one of the best Silverado horsepower upgrades you can get for your truck.

Stock exhaust systems aren't built for power. All manufacturers, including Chevy, prioritize quiet operation over efficiency to appeal to the largest demographic of customers. Thankfully, aftermarket manufacturers like us don't have to worry about that. These Silverado upgrades are designed to give drivers an increase in horsepower and torque, along with an incredibly aggressive exhaust note to make your presence known on the road.

With a cat-back Silverado exhaust system, your exhaust gases will flow easier, giving you performance gains anywhere from 10 to 20 horsepower and 5 to 15 lb-ft. of torque.

2. Let Your Engine Breath Easier With a Cold Air Intake

Next on our list of the best performance upgrades for a 5.3 or 6.2 Silverado is a true classic: the cold air intake. Cold air intake Chevy Silverado mods are designed to accentuate your engine's power, letting it "breathe" better with oxygen-rich, cold air.

But how do they do it? Cold air intakes provide two major benefits to outperform your stock setup. First, they remove the sound baffling all stock Silverado intakes have. This baffling only exists to quiet your engine more, so they aren't essential. Removing them only makes your engine sound way better. Second, these Silverado performance upgrades collect air from outside rather than inside your engine compartment. The air outside your engine is cooler and denser, which means it's way richer in oxygen. With more oxygen, you'll be able to burn more fuel and get some sweet performance gains.

Cold air intakes are another of our favorite Silverado horsepower upgrades, though your gains won't be massive. Depending on your setup, these simple bolt-on Chevy Silverado mods can add up to anywhere from 6 to 11 more horsepower. You'll also see improved fuel economy and throttle response, which everyone can benefit from.

3. Maintain Optimal Performance With an Oil Catch Can

One of the best upgrades for 5.3 and 6.2 Silverados is also the simplest: the oil catch can. In addition to optimizing your performance, these precision Chevy Silverado mods are essential for increasing the longevity of your engine.

An oil catch can is designed to eliminate blow-by of gas, water, oil vapors and particulates from your engine's airpath. In an internal combustion engine, the process generates these blow-by products and power. If left unchecked, blow-by can accumulate within the intake system and cause massive amounts of carbon buildup, impeding your airflow and contaminating your air-fuel mixture. Eventually, this will cause your overall efficiency and performance to decrease.

You won't have to worry about blow-by with an oil catch can. These Silverado performance upgrades are the best way to prevent it from re-entering your intake tract. That means improved throttle response, enhanced horsepower and increased torque.

4. Optimize Your Upgrades With a Chip Tune

If you're looking for more horsepower from your truck, you want to get your PCM tuned. However, we recommend staying away from your dealership. When dealerships do factory tunes, they optimize for quiet operation, smooth shifting and factory-recommended power. If you need a real Silverado horsepower upgrade, you'll want to pick up an aftermarket chip tuner.

Chip tuners are pre-programmed handheld units you can plug into your OBD-II port to reconfigure the parameters of your engine. Depending on your needs, an engine tune is the best way to improve your throttle response, get better fuel economy and increase your horsepower and torque. But that's not even the half of it. A chip tune will increase your performance even if you drive with stock parts. If you have other Silverado performance upgrades like cold air intakes and exhaust systems installed, you can make them even more powerful.

5. Shed Some Seconds With Weight Removal

This technically isn't a Silverado upgrade, but it still works better than you'd think. Weight removal won't put any extra power into your engine, but it will let you use your existing power more efficiently.

Think about it like this: every extra pound you add to your truck will demand more power from your engine. For example, a 100-pound load can decrease your engine efficiency by one to two percent – that's a lot of power loss for a relatively small amount of cargo. You can accomplish weight removal in a lot of simple ways.

Think about removing items like:

  • Non-essential electrical parts
  • Unused interior components
  • Non-essential exterior accessories

What you take off is entirely up to you; just ensure you don't remove anything that produces power.
