However, it not only optimizes sound, but it also improves engine performance. Although its effect on horsepower is quite minimal, it still manages to achieve minimal power increase from increased air inflow.

Like many of the most durable systems, it is made from high-quality stainless steel material for a high durability effect.

One of the things you can expect from this system is increased engine airflow, leading to better engine performance. Also, it’s made from stainless steel material – the most durable exhaust material you can get.

Another striking effect is the sound it produces. It produces drone less, but audible sounds at low RPMs, and at higher RPMs, it produces commensurately loud sounds.

How to Choose The Right Exhaust System for a C6 Corvette?

Picking the right exhaust system for your C6 corvette is dependent on your personal preference and the options available. In addition to collecting and removing exhaust gases from the engine, exhaust systems help automobile engines to operate with minimal noise. 

As the quality of exhaust influences engine performance and sound, you should be aware of a few factors that can help you choose the perfect exhaust system for your automobile.

The Material

This is arguably the most critical factor to consider. Material directly influences the durability of an exhaust system. If you hope to buy a long-lasting model, selecting a relatively strong material is critical. The strongest exhaust systems are made out of aluminized steel or pure stainless steel. There are medium stainless steel options available, but you should know that they are not as strong and are more likely to rust and corrode faster.

Sound

Sound is a principal reason why people buy aftermarket exhaust systems. While they perform the primary function of controlling the engine’s noise, the sound produced by each exhaust type varies. For example, if you want a more aggressive exhaust tone from your C6 corvette, you can opt for an axle-back exhaust system or a cat-back exhaust system.

Vehicle Compatibility

It is important that you choose a compatible exhaust system for your C6 corvette. Attaching a misfit system can affect your engine. You want to make sure that your exhaust choice meets your vehicle’s model’s requirement and the engine type and size.

Configuration

Exhaust systems can be double or single systems. Typically, single exhausts can give high torque and power compared to double exhausts, but they produce more noise. Double exhaust systems are sometimes preferred for the visual effect they have. Nonetheless, they come with double mufflers that make them more effective in reducing engine noise.

Price

Like with all other car components, exhaust price varies from model to model. This is why you should set a budget before shopping for an exhaust system. The most important thing is to get the best quality model you can at a reasonable price. You should know that quality and features will vary with the price. A cheaper model will come with fewer features and have less quality than a high-end model.

Corvette Exhaust Systems: What Do I Need?

Most corvette lovers are well informed about these automobiles and their components. However, if you are new to the corvette world and don’t know much about compatible exhaust systems, here are some things to look out for. Please read this article carefully before going to select a new exhaust system.

Typically, corvette exhaust systems are either Cat-Back or Axle-Back. While they both can produce the sound effects many corvette enthusiasts love, there are significant differences in prices and performance.

When the sound effect is the most critical factor for shopping for an aftermarket exhaust system, axle-back systems are the best. They may not have the most significant effect on horsepower and torque. Still, they can offer a wide range of exhaust volume, tone, and rumble, depending on the manufacturer and model selected.

On the other hand, if you’re concerned with the effect on engine performance as much as you are about the sound, cat-back exhaust systems have a more inclusive set of features to deliver both. However, they are usually more expensive, as they come with more parts.

Why Change a C6 Corvette Exhaust System?

There are two primary reasons people opt to change C6 corvette exhaust systems, and they are customizing the vehicle sound and maximizing the vehicle’s performance. Factory-fitted corvette exhausts work just fine, but the beauty of owning a corvette is in being able to make tweaks to the sound, engine, and body. This reveals the style and personality of the car owner.

Aftermarket exhausts do offer more power and sound effects compared to stock exhaust systems. Nevertheless, the most important thing is to have a valid basis for buying an aftermarket model. Depending on the manufacturer and type of exhaust, they can also perform the added functions of ensuring efficient energy consumption and torque maximization.

How to Remove a C6 Corvette Exhaust?

While it is pretty straightforward to remove a C6 corvette exhaust, we don’t recommend a DIY approach if you don’t have experience in related automobile work; nevertheless, if you feel confident in your ability to carry on, here’s how to remove the exhaust.

Locate the bolts connecting H-pipe to Cat. Remove them. Next, disconnect H-pipe and the over-axle pipe by removing the pipe connection and pushing the H-pipe forward. Release the hangers by shoving the mufflers forward.  Now, you can separate the axle pipes and axles.

Will a C6 Corvette Exhaust Fit a C5 Corvette?

Ordinarily, a C5 corvette is not a match with C6 corvette exhausts. The ports on the exhausts are not designed to fit those on the block. However, certain modifications can be made to the exhaust to make it fit. All in all, buying and attaching a mismatched exhaust system should be avoided.

Will a C6 Corvette exhaust fit a C5 Corvette?

The two Corvettes have a similar shape, so they’ll likely fit one another. However, the C6 has different mounting holes than the C5, and therefore the exhaust system may need to be modified slightly. To make things even trickier, the C6 Corvette was made available only in a coupe and convertible form, while the C5 came in coupe and roadster variants.

What is the downside of owning a Corvette?

The most obvious downside of owning a Corvette is the cost. Even though it’s more affordable than some sports cars, you’re still looking at sticker prices in the mid-twenties for a new car. Another drawback to consider is that these are high-performance vehicles, so they aren’t the best choice for long-distance driving. If you’re looking to commute to work every day, a less expensive car might be more practical.
