What are Performance Upgrades for C6 Corvette?
Performance upgrades are vital for getting more power out of your engine. Without them, your C6 Corvette will never reach its true potential.
For instance, you could go for a cold air intake and increase your horsepower and engine noise.
On the other hand, you could get a better exhaust system to improve both your performance and your car’s noise.
How Do Performance Upgrade Kits Improve the Performance of C6 Corvette?
- Supercharger upgrade kit — this is one of the easiest, although expensive ways, to increase your vehicle’s performance. This happens as the supercharger increases the air going into the engine, increasing your performance.
- Twin-turbo kit — another turbo you can get to improve performance is the twin-turbo. This type of turbo severely reduces turbo lag, making it perfect for a performance upgrade.
Which Component Upgrades Boost the Performance?
- Cold air intake — the C6 Corvette is one kind, but the air intake is pretty restrictive and must be replaced if you want to make more power. Thus, get a cold air intake to increase airflow.
- Supercharger — for even more horsepower, consider getting a supercharger. This is the most well-known method to increase HP.
- Throttle body — a bigger throttle body, combined with an induction system upgrade is an excellent addition to make your vehicle faster.
- Programming tuner — getting a tuner doesn’t do too much if you haven’t installed other mods. At most, it’ll make the throttle’s response better, but if you get a cold air intake, you’ll notice the HP boost.
C6 Corvette Performance Upgrades Kits
We extensively reviewed countless C6 Corvette performance upgrades and then broke them down into an extensive list, including explaining why they are worthy of an upgrade. Ready to know more? Well, take a look:
Cold Air Intake
How does cold air intake improve performance?
After installing an aftermarket cold air intake, you will eliminate all those restrictions imposed by the stock part.
This is done by flowing as much air as possible into the engine, improving your overall performance.
While the difference is not something to write home about, you’re still getting a considerable boost.
Which improvement you will look after the installation
While some drivers might argue that intakes are purely a sound upgrade, you’re still getting a horsepower boost after installing one.
Still, in many cases, you should gain anywhere from 5HP to 10HP.
As long as you don’t get a cheap one, you should notice some performance boost. If you want to know more about cold air intakes, check this video out:

Exhaust System
How does an exhaust system improve C6 Corvette performance?
If you’ve done some research about exhaust systems, you probably know the stock exhaust has many restrictions, ultimately reducing your horsepower.
Upon doing research, you might also find that replacing the muffler could make more power.
However, this is not enough to delete all the restrictions imposed by the stock exhaust. Instead, get a new stock system to make more horsepower.
Which improvement you will look after the installation
Finding out how much power you’ll get after replacing your stock exhaust system heavily depends on the vehicle and engine.
For instance, the headers and the cat on some cars can be more restrictive than the exhaust itself.
But for the C6 Corvette, you should be looking at 10-20 gains. But for more power, we suggest tuning the engine.
Finally, replacing the stock exhaust will make your car sound louder. Take a look at this video for more details:
