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.

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.

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.

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.

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.

Apart from this, you can choose which exhaust chooses your style best, based on its features.
You can choose how loud you want it to be or if you want to be lower at lower speeds; there are many options to choose from.
