• Headers and muffler systems are two items you should consider for your Corvette's.
• Backpressure is definetly not ideal.
• Choose the Muffler Wisely.
• Same with Overall Exhaust Systems

Something restrictive does not sound like an appealing aftermarket part to be putting on your Corvette, considering the term restriction in the automotive world is a bad thing. This is the same with exhaust, the last thing you want to do is restrict the exhaust gases from exiting your car. This is for two reasons, first because if the exhaust gases don't leave your engine in a hurry it will create backpressure and not allow the exhaust  gases behind it to escape causing your Corvettes engine to rev slower and this is definetly not ideal.

The second reason is based on the scientific theory of thermodynamics which essentially says that hot air rises and cold air sinks. What this means is the hot air in your exhaust is less dense and thus light while cold air is more dense and heavier. OEM Corvette exhaust systems are the most restrictive systems you will find on the market and any replacement muffler and cat back systems will release lost horsepower.

A muffler designed to use acoustics to eliminate sound traveling through the Corvette exhaust. This is done by creating interference of the sound waves within the muffler, in this case deconstructive interference. Muffler designers do so by creating partitions within the muffler that reflects certain segments of a sound wave from your Corvette's exhaust, that will cancel out another sound wave coming into the muffler. This is great for dampening the sound of the exhausts muffler but isn't as free flowing as an absorption style muffler.

In summing up, the importance of the exhaust systems and why replacement systems are essential to overall performance gains for your Corvette is probably the reason why you're here. So, let's keep a few things in mind when selecting a replacement muffler or exhaust systems. First, and foremost, by changing to replacement exhaust systems no true horsepower is made it is only freeing up lost horsepower from restrictive OEM systems.

Secondly, when making an exhaust selection of header systems and or crossover pipe, you must consider both for your Corvette because if you have long tube header systems you will need a short crossover pipe and vice versa. This shouldn't affect your cat back since a crossover exhaust pipe and muffler, both short and long, are designed to match with almost any cat back kit.

Lastly, since your Corvette is already a high horsepower machine upgrading the muffler and exhaust systems is not a bad idea, but if you intend to upgrade other parts of your bowtie like the exhaust manifolds and intake or add some form of forced induction or power adder then upgrading your exhaust is essential to optimizing the potential of your Corvette. Think of it this way: if your Corvette still has the OEM muffler and exhaust systems and other performance modifications have been made, the exhaust will not properly reflect the results you should have. By upgrading the muffler and exhaust systems it compliments other performance mods, or preps your Corvette for other future modifications.
