An overwhelming majority of 2020 Corvette buyers selected the optional Performance Exhaust (RPO code NPP) when ordering their car.
According to statistics that were recently released by the C8 Corvette sales team, a whopping 89% of 2020 Corvette buyers selected the RPO code NPP Performance Exhaust option. The Performance Exhaust is a $1,195 option and increases power and torque from 490 horsepower and 465 pound-feet of torque to 495 horsepower and 470 pound-feet. The exhaust is standard with the available Z51 Performance Package, but is also available separate from the Z51 package. In addition to the Performance Exhaust, the Z51 package also includes an Electronic Limited-Slip Differential, a different rear axle ratio and Brembo brakes.
It’s no surprise to see that many 2020 Corvette buyers are deciding to check the box for the optional Performance Exhaust kit. Not only is this kit a relatively cheap way to get an extra five horsepower and five pound-feet of torque from the already powerful 6.2L LT2 V8 engine, it also gives the mid-engine sports car a meaner and more defined exhaust note.
The aftermarket has begun to offer some alternatives to the factory Performance Exhaust kit. Hennessey Performance recently debuted its new exhaust kit for the 2020 Corvette, which boosts engine output by 21 horsepower and 19 pound-feet of torque from stock. The Hennessey exhaust is also 10 pounds lighter than either of the Chevrolet factory exhausts. Hennessey plans on making just 1,000 units of the exhaust for all of 2020 and 2021 and prices will start at a fairly steep $3,495.
While the aftermarket is beginning to come through for the 2020 Corvette, many owners are still limited on the modifications they can perform on the vehicle for a variety of reasons. Until then, the Chevrolet Performance Exhaust remains a very popular way to give the mid-engine sports car a little bit more presence and personality.

This just speaks to how cheap people really are! Why would you buy a performance car and not select all the performance options? These are normal upgrades weather you track the car or not!
I wouldn’t, I’d wait for aftermarket to make a better system
The MPG will probably increase by at least 1 MPG with the factory performance exhaust option. The aftermarket units may increase it even more MPG than the factory optional unit. For over $3,000 for the high end aftermarket units, i would deal with a local muffler shop that has the computerized tube bending equipment. I’ll bet the local high tech muffler shop will only charge a few hundred dollars to make a more open exhaust system, if only some part of the factory unit are replaced and not the whole system. It will probably be too loud to pass state noise regulations so a remote exhaust cutout, that are controlled from inside the car, will solve that issue. Open it up wide on the highway and use it half open in the urban areas where more people are around, then close it driving in your own neighborhood.
The high-performance exhaust options from the aftermarket seem to be growing, Beside the Hennessey system, I’ve seen about four others offered on YouTube Videos, including one made by a Hi-Perf shop, in Alberta, Canada, that is made totally out of titanium, and weighs about 25 pounds, compared to the factory system that weighs about 100 pounds. Whoever thought that someone would develop a cat-back exhaust system that could save about 75 pounds, in one step? So, it’s likely more aftermarket systems are on their way.
The performance exhaust option is like the Z51 package, it offers so much more than the expense that it makes sense to check this box instead of trying to get the C8 Corvette out the door for as close as retail as possible to save money.
Love the articles/videos of aftermarket efforts for the C-8. It would be helpful to know which of these aftermarket systems will negate the factory warranty, and specifically which assemblies would be excluded from the warranty. Thanks!
Aftermarket anything to your new C8 could possibly invalidate the original Warranty. I know for sure if you add anything to a Porsche, not manufactured by Porsche. The Warranty will be terminated. I was speaking to a Porsche Sales regarding a 1 year old 911 and asked about the remaining Warranty. Sales person relayed NO Warranty because the previous owner changed the Radio and added speakers.
But perhaps GM has a different point?.
