Borla Exhaust 2020-2023 Chevrolet Corvette C8 Cat-Back ATAK System with NPP Valves T-304 Stainless Steel

If you're lucky enough to own a 2020-2024 Chevrolet Corvette Stingray, you know that the driving experience is something special. But if you're looking to amp up that experience, let me tell you about the BORLA Cat-Back Exhaust System, part number 140908BC. This isn't just any exhaust system; it’s designed for models with a Gas Particulate Filter (GPF) in the exhaust system, though keep in mind, it’s not available in North America.

The engineers at BORLA faced some unique challenges while developing this system for the C8 Corvette, but they nailed it. They put a lot of thought into maintaining both the integrity of the vehicle and the performance of the exhaust. One thing to note is that this system doesn’t come with Active Fuel Management (AFM) valves, but it does include NPP dual mode exhaust valves, which means you can enjoy a more aggressive sound whenever you want. And let me tell you, the ATAK sound level is something else—it's the loudest and most aggressive option they offer, giving your ride an exhilarating roar without the annoying drone that can ruin a good drive.

What really sets this exhaust apart is the Polyphonic Harmonizer and SwitchFire technology. The Polyphonic Harmonizer uses a clever design with pipes of different diameters and lengths, creating multiple exhaust notes that blend together beautifully. This means you get a clean, rich sound that really enhances the driving experience. Plus, the SwitchFire design eliminates the turbulent center intersection you find in standard X-Pipes, which helps blend the combustion pulses from both sides of the engine for a smoother performance and a custom sound that’s uniquely yours.

Now, let’s talk about durability. This system is built from T-304 stainless steel, so you know it’s going to hold up against the elements. It also comes with 4-inch Black Chrome tips, which not only look great but also add a touch of class to your rear end. If you prefer a brighter finish, there’s an option with bright chrome tips too. And don’t forget, it’s backed by BORLA’s Million Mile Warranty, which is a testament to their confidence in the product.

Just a heads-up: after you install this system, you’ll need to recalibrate the NPP valve controllers according to GM Document ID 5406413. It’s a good idea to take your car to a Chevrolet dealer for that service to ensure everything is set up perfectly.

So, if you're ready to take your Corvette's sound and performance to the next level, the BORLA Cat-Back Exhaust System is definitely worth considering.
