While already a powerhouse, Chevy’s popular Corvette sports car makes a fantastic platform for gearheads and automotive enthusiasts looking to take their rides to the next level. One such aftermarket upgrade is installing performance headers to boost engine efficiency and power.
To help you shop with confidence, this article explores how to choose the best Corvette headers for your needs, specifically focusing on sixth-gen C6 (2005-2013) and eighth-gen C8 (2020-present) models.
But first, we’ll provide a quick catch-up on what exhaust headers are and what they can do for sports cars like the C6 and C8 Chevrolet Corvettes. Finally, we’ll reveal some of the best exhaust header options currently on the market, from respected brands such as Flowtech, JBA, Billy Boat, and Corsa.
Let’s get started.
How Headers Work and What Exhaust Headers Do on Corvettes
Simply put, headers are a type of exhaust manifold. Unlike the traditional stock manifolds, performance headers are designed for optimized exhaust gas flow. They consist of individual tubes for each cylinder that merge into a larger pipe, known as the collector.
The primary function of headers is to make it easier for the engine to push exhaust gas out of the cylinders. In standard manifolds, the exhaust gas from different cylinders can clash, causing back pressure, which is basically wasted energy.
Adding C8 or C6 Corvette headers resolves this problem by providing each cylinder with its own mini-exhaust pipe, which means the gas from one cylinder won't interfere with those from another. This efficient expulsion of exhaust gas provides several benefits, including a noticeable increase in horsepower, improved torque, and often, a more aggressive exhaust note.
By reducing back pressure, your Corvette’s engine will breathe better and perform more efficiently. This makes headers a must-have upgrade for C6 and C8 owners looking to unlock their car’s full potential.
Best Exhaust Header for C6 Engine
The sixth-gen Corvette C6 boasted a variety of engines, including the LS2, LS3, and the formidable LS7 in the Z06. Selecting the right exhaust header for these engines can further enhance their performance.
Whether you own the base model with its robust LS2 or the track-focused Z06 with the LS7, upgrading the exhaust system is key to unlocking additional power and efficiency.
Below, we'll explore some top exhaust header choices for the C6 Corvette, including options from Flowtech, JBA, and Billy Boat:
