[VIDEO] Comparison of the 2020 Corvette's Two Different Exhaust Systems

Chevrolet’s 2020 Corvette is available with a number of performance upgrades, and for new Corvette buyers, it can be a challenge in deciding which of those options to add.

Case in point is the Corvette’s NPP dual-mode performance exhaust system. If you check the box for the Z51 performance package the NPP exhaust is added with the package. Non-Z51 buyers can add the NPP for an additional $1,195.

But that still doesn’t tell you whether or not you need it. With the C7 Corvette, the NPP added an additional 5-horsepower to the car but as the SAE tests of the C8 showed, the NPP only ads an extra 1.2 hp and 0.8 lb-ft of torque. So what you are really paying for it the ability to adjust the sound. The NPP is tuned in such a way to offer a different sound depending on the Driver Mode selected. With a twist of the knob, you can select Stealth, Touring, Sport, and Track.

Our friend Jake who runs the MidwestRide YouTube channel is back in business following his well-publicized engine failure and warranty replacement, has a new video out that allows you to hear the difference between the two exhaust systems:

Sound comparison between the Performance Exhaust (Z51) vs. Stock Exhaust (Non-Z51). Both filmed on same camera (Canon M50) AND same Microphone (Rode VideoMic Pro+) Let me know in the comments if you’d like to see anymore comparisons on a stock 2020 Corvette vs. the Z51!!!

While the non-NPP exhaust still sounds great, unless you are planning to go with an aftermarket system, it’s our recommendation to add the NPP to your Corvette. It’s covered by the Powertrain warranty, it’s adjustable, and it will add to the resale value of the car. For more info on the NPP, here’s a previous post that details Tenneco’s C8 Corvette Exhaust System.

  1. Some dealers have played greedy on the first 2020 allocations and placed their stock orders ahead of customer orders. I canceled my order after my dealer would not give me a order status. I learned from the C concierge that my order was still at 1100 status. The dealer would have their stock order 2020 cars at a $20K “market adjustment.

  2. Just like jog pointed out, I don’t think this was quite a fair comparison. I have a C7 with NPP exhaust. I can tell a noticeable difference in sound when I start the car in my garage versus starting it out in the open. I keep my exhaust set on track all the time because I like the aggressive sound.
