Throughout 1997-2004 Chevrolet produced the fifth generation, C5 Corvette paired with a 5.7L V8 producing 345hp at 5,600rpm and 340lb-ft of torque at 4,400rpm, introducing modern technology and features such as fully independent rear suspension, improved handling, lightweight, head's up display, and re-defined interior compared to it's ancestors. The C5 Corvette's design was a sleeker and more aerodynamic, contributing to it's high speed stability. A couple years later, Chevrolet introduced the 2nd generation Corvette Z06 still paired with a 5.7L V8, however this model produced 405hp at 6,000rpm and 400lb-ft or torque at 4,800rpm. Ready to take your ride to the next level? Let's talk about how to transform your ride from mild to wild!
1. Cold Air Intake
Estimated Cost: $400-$600 CAD
A cold air intake (CAI) is a great upgrade for a C5 Corvette because it helps the engine get cooler, denser air, which is crucial for improving performance. When the engine breathes in colder air, it can burn fuel more efficiently, which leads to more power. This increase in airflow allows the engine to produce more horsepower and torque, particularly at higher RPMs, giving the car better acceleration and quicker throttle response.
Installing a CAI is also a relatively simple and affordable way to boost your Corvette’s performance without needing major modifications.
2. Throttle Body
Estimated Cost: $850 CAD
Installing a brand new bigger throttle body on your C5 Corvette will provide more air flow into the engine, which leads to more power, torque, acceleration, and overall performance.
When larger throttle bodies open, more air can flow into the intake manifold, allowing for a higher air-fuel ratio that increases efficiency of the engine, which leads to the engine to produce more power.
The increased airflow contributes to better internal combustion, greater performance, and improved throttle response.

3. Intake Manifold
Estimated Cost: $1,850 CAD
Purchasing a new intake manifold for a C5 Corvette can be a great idea if you're looking to improve the vehicle's performance, efficiency, or overall reliability. The stock intake manifold on the C5 Corvette, while adequate for normal driving, can become restrictive as you modify other components or push the engine's performance limits. An upgraded intake manifold can significantly improve airflow to the engine, increasing horsepower and torque, especially when combined with other performance mods like a cold air intake or exhaust system.

MSD Atomic Airforce
Holley Hi-Ram EFI
4. Longtube Headers w/ Connection Pipe (X or H)
Estimated Cost: $4,200 CAD
Longtube headers improve the exhaust flow by providing a more direct path for exhaust gases exiting the engine, leading to reduced back pressure, and allowing the engine to breathe more freely, making it a top performance modification for the C5 Corvette.
Not only will longtube headers add performance gains, they will add a raw V8 sounds. With less restriction in the exhaust system, the engine produces a deeper, aggressive, that is bound to turn heads.
The main differences between X and H connection pipes are in there design. The X pipe, designed in a crossing "X" is more known for it's efficiencies and higher pitched, and raspy sound. While the H pipe has a much simpler design, it's less efficient due to the horizontal pipe connecting the two exhaust sides. The H pipe produces a lower, classical V8 muscle car sound.
Notable Longtube header brands for LS1 5.7L V8:
Kooks
American Racing Headers
Stainless Works
6. Tuning w/ HPtuners
Now that your C5 Corvette can breathe properly without any restrictions, tuning becomes the next essential component to be able to unlock the true potential of your C5 Corvette.
With HPtuners MPVI3 and (2) Universal Credits you or your tuner will be able to maximize the power out of your C5 Corvette while making it as efficient as possible.
Estimated Cost: $1,500
Estimated Total: $9,000
Upgrading your C5 Corvette with performance parts such as a cold air intake, larger throttle body, intake manifold, longtube headers, and a tuning solution like HPtuners can drastically elevate the power, performance, and overall driving experience. These modifications unlock the full potential of the 5.7L V8 engine, improving airflow, increasing horsepower and torque, and providing a more responsive throttle. Whether you're looking for better acceleration, quicker throttle response, or a more aggressive exhaust note, each of these enhancements will take your Corvette from mild to wild, ensuring it performs at its absolute best on the road or track.
