Coming in number 1 on the list is the SLP 31077 Lord Mouth Exhaust System. It is a hand-crafted item made from 304 stainless, providing strength and long life durability.

This, combined with the additional 12 horsepower your Corvette gains, ensures the build quality.

Not only this, it has a modular design, so you can now change the muffler to an SLP bullet-style muffler. It is a wonderful idea for someone who desires to personalize their car.

The unique point of the Lord Mouth is its sound, a very loud rumble, so now you can drive your Corvette feeling like you’re driving an actual sports car, grabbing the attention of everyone around.

Therefore, it is perfect for those who love to listen to the car’s sound, regardless of what speed they’re going at.

Comparatively, the 31077 Lord Mouth is not that expensive, so it is the perfect package for someone who wants a new sound for their sports car without draining their pockets.

However, the aggressive sound that this exhaust produces might not be preferred in some conditions

  • Additional 12 horsepower
  • Modular design
  • Aggressive noise (perfect for a sports car)
  • Easy to install
  • Comparatively lower price

Another interesting sound for your engine might be the Borla 11815 S Type II Exhaust Rear Section.

This model has 4.00” Dual Round Rolled Angle-Cut Tips and is made of 300 stainless steel. Not only this, it has been Dyno tested to increase Horsepower and Torque.

The stainless steel gives stability and optimization, whereas the horsepower also increases by around 7 – 10%.

It has a great, high-frequency sound, and the exhaust is even legal in 50+ states.

What more do you want?

The noise depends on the RPM. Thriving best at higher RPMs, over 3500 RPMs, it sounds the best. So you won’t be disturbed by any loud sounds when going at lower speeds.

However, when you’re racing, you’ll experience a very attractive sound, which becomes loudest when pushing the throttle.

According to Borla, the design is for zero drones, hence better performance due to high flow technology.

It is a world-renowned product, and Borla even gives a million miles’ warranty.

Isn’t that amazing?

A million miles can last a lifetime. But the best part, I would say, is the fuel economy, the cherry on top.

Combined with the high performance, the Borla 11815 allows you to run more miles using lesser fuel, owing to Borla’s award-winning technology.

Lastly, you may experience very little sound performance when you newly install this exhaust; the problem will be fixed by sometime of usage.

A major problem is that it doesn’t fit the 2005 Corvette very well, so you may have to think accordingly.

  • Horsepower increased by 7 – 10 %
  • Street legality in 50 + states
  • Million miles warranty
  • Fuel economy
  • Sound quality
  • It doesn't fit the 2005 Corvette well

This exhaust has the advantage of having different noises at acceleration and cruising.

The fuel economy just gives it an edge over any product in the market, so if fuel economy is your thing, then this product is for you. Besides, the sound quality is wonderful.

Designed, engineered, and manufactured in Berea, OH, the USA, the Corsa 14169 is made for those who want both an aggressive sound and high performance.

However, I have to inform you that this model is made for only the 2005 – 2008 Corvettes; if you have a different model, this is not for you.

It is made of stainless steel and has a premium clamp-on tip design, a 35% airflow increase, a 13 ft. per lbs more torque, and, yes, a 12% increase in horsepower.

So when you’re cruising, you can choose not to have that aggressive sound that might be found annoying.

The voice is generally a bit deep and aggressive but not too much; if you need something similar, then here you are.

The best feature of this product is the double-walled makeup to protect against heat.

It improves performance and the durable design; the lifetime warranty ensures that it is here to last. This product is also customizable due to the clamp-on-tip design.

You can change the exhaust tips, changing how your exhaust looks and sounds, according to how you want.

Borla 11822 Rear-Section Exhaust System is focused very much on sound, giving the best sound quality possible.

This is actually because of the Acoustically-Tuned Applied Kinetics, which is a technology that helps boost up the noise of the exhaust to the maximum level that is allowed by law.

You will enjoy the best sound you desire with this engine. If you listen to the sound and like it, then definitely buy it because Borla ensures their products’ quality.

It is actually known in the market for the best sounding exhausts, telling everyone around about your car and its ear-catching sound, so it is worth a try if you were initially looking for an exhaust primarily for the noise feature.

The voice is increased without distorting voice clarity, and it also controls resonance on the highway.

It is the perfect solution for those who love listening to their car more than or as much as driving it.

It has been dyno tested as well to increase horsepower and torque and also removes exhaust gases pretty efficiently, a lot better than the rest of the exhausts in the market, as a matter of fact.

Borla actually designs different exhausts for different versions of Corvettes instead of trying to fit all of them, ensuring excellent quality and performance because they are made to fit certain models.

For example, the C6, C5, and C7 exhaust cores are all different from each other.

Being the loudest isn’t the only good thing, however. It even increases horsepower by up to 10%, all while lowering your fuel consumption.

The downsides to this one are that it comes with welded tips and is very difficult to install by yourself.
  • Loudest noise
  • ATAK technology to give the best sound quality
  • Increases horsepower by up to 10%
  • Lowers fuel consumption
  • Welded tips
  • Hard to install

Improving sound quality is one of the primary functions of a race car exhaust, and this model covers that really well.

I would say it is an excellent quality exhaust in terms of sound while not even compromising on performance.

It still gives a remarkable performance. So if you really prefer the best sounding exhaust for your C6 Corvette, get the Borla ATAK.

Next up, I have the NXTSTEP PERFORMANCE Axle Black Exhaust. It is basically best if you are on a budget wanting to improve your engine sound.

This exhaust is louder than the stock Corvette exhaust but not too much; it might not be as good as the other exhausts in the market in terms of its sound, but let’s say that compromise is due to the fairly low price.

In fact, it isn’t bad, though. Let me tell you the good features!

This one, compatible with the 2009 – 2013 Corvette, is made of stainless steel, which is highly polished, and T304 quad tips, 4’’ wall tips that are dual.

Moreover, these have direct bolt-on installation with Factory Hangers and come with clamps.

Moreover, it is legal in 50+ states and comes with a lifetime warranty. The TIG is welded for better strength and visual appeal, along with the T304 mirror-polished tips.

Despite being better than the stock exhaust, it has a slight drone when idling or cruising down the road.

It claims to improve the performance, but just fully, it doesn’t really improve the performance much in reality.

Due to higher airflow, the power must increase, but that is not actually the case with this product.

  • Improves sound performance
  • Lower price
  • Lifetime warranty
  • Sound not too loud
  • Performance not really improved much

This model may not look like the best-sounding exhaust for your Corvette, but it literally comes in around half the price and the other ones in the market.

I would say if you’re on a budget, that this is not too much of a bad idea, the sound quality is better than the original stock exhaust, so you can improve that by not spending too much, that is, if you’re not deliberately looking for something quite extra, this might not be a bad choice for you.

This one is for those on a budget!
