The 2023 Chevy Corvette Z06 stands apart from the Corvette C8 Stingray for a number of reasons, not the least of which is the Z06’s revised exterior and extra-aggressive styling. Notably, the new Corvette Z06 is also equipped with four centrally placed exhaust pipes, whereas the C8 Stingray features outboard exhaust pipes. Now, however, GM says that the 2023 Corvette Z06 will in fact come equipped with an outboard exhaust treatment for some foreign markets.
The reason behind the revised exhaust location for some foreign markets is due to the required installation of a gas particulate filter. For the moment, it’s unclear which foreign markets will require the gas particulate filter and outboard exhaust treatment, as GM says it’s currently “focused on the Corvette Z06 for the domestic market.”
According to a Chevy spokesperson, the brand will “communicate details referring to export versions later in due time.”
GM unveiled the C8 Corvette Z06 in October, showing off four centrally placed exhaust pipes with a series of official photos. However, GM Authority has also spotted examples of the Corvette Z06 equipped with outboard exhaust pipes. According to a GM spokesperson, as GM Authority reported last month, “The outboard exhaust was our original design, the center exhaust is the latest – there will not be a choice available.”
As for what those exhaust pipes are connecting to, the 2023 Corvette Z06 is motivated by the naturally aspirated 5.5L V8 LT6 gasoline engine, which is rated at 670 horsepower and 470 pound-feet of torque, and can spin up to a 8,600-rpm redline. Output is routed to the rear wheels through the revised GM eight-speed dual-clutch automatic transmission co-developed with Tremec.
Under the body panels, the 2023 Corvette Z06 rides on the GM Y2 platform. Production takes place exclusively at the GM Bowling Green plant in Kentucky.

Any country that follows Euro 6 emissions will need a GPF. That’s EU/EEA and the UK. It will also have it if it does to go to China, which has their version (China 6). Japan generally follows US emissions and won’t need one.
Australia/NZ does not currently require it as they are on Euro 5 and also accept US emissions, but there is ongoing debate whether they will adopt Euro 6. (The holdup is that they allow 15x the sulfur in gasoline as the US and EU does) The GCC countries are the same since they have the same sulfur issue.
Excellent explanation, thank you
Additional info:
In EUROPE the fuel is sulphur-free! That is why the particle filter is also possible for petrol engines!
And a note for the EPA:
Particle filters at ICE save lives, whether people or animals, and improve the air we breathe!
The GPF is needed for the Euro 6 particulate number requirement. Gas cars meet particulate mass requirements without a filter. The Europeans are scared about ultrafine particulates, hence the standard. The major reason why you shouldn’t use a GPF is it drops fuel economy.
The fact is that there’s no “one size fits all”. The US, particularly CA Emissions, is much stricter in smog-forming NOx emissions over Europe: that’s why diesel cars were effective banned until VW, Mercedes, and FCA cheated. The US has much more sun but not much dense cities. Particulate pollution is less of a problem in the US than ground-level ozone which is caused by NOx emissions.
The other thing where Europe lags is that they haven’t banned MTBE yet, whereas the US has replaced it fully with ethanol 2 decades ago.
Of course, the elusive MSRP is still not being disclosed. Although I am beginning to suspect that certain wealthy people are being shipped their Z06′ for private collections.
Your wondering is not elusive. Haha… It’s happening and it’s none of our business.
Just count on it starting at 92k and if it’s less …. Merry Christmas or Happy Anniversary
Unfortunately… does it even mater? These won’t sell at close to MSRP for 1-2 years.
Big mistake, the inboard exhaust is much cooler than the outboards and what is GM doing? Did they ever consider America first? They should fill all the US orders before exporting the Corvette to any other country.
GM needs to fix the C8 adding grills. It is beyond reason why apparently now it is ok to install them obviously due to radiator damage. They may face a recall but should step forward now and show loyal customers that they are willing to fix this issue. From can’t use them due to reduced airflow and damage ok to hey pay to add them is absolutely ridiculous!
I added front radiator grill screens on my ’21 Z51. Never ever noticed any negative effects on engine cooling even in 100+ temps – both on the highway or sitting in traffic. Thankfully, my dealer didn’t balk at the addition. In fact, my dealer would even install certain after market grill screens.
Great but GM should be putting them on at no cost to fix a clear design defect
So here is my question to the Corvette Gang….does the center mounted exhaust add or subtract (or leave identical) the horsepower and torque figures for the new Z06 engine compared to the side exit exhaust? I find it somewhat odd that they’d produce the same HP and torque as Chevy has gone to a lot of trouble to produce the exact HP and torque figures touting them as “best in the world for a non power added engine”. Will those foreign delivered C8 Z06’s produce worse performance figures, or better than the ones delivered in the USA? Probably won’t make too much of a difference, but “enquiring minds want to know”! So what does everyone else think…same or better horsepower & torque figures with the “old exhaust”?
Let’s see how many more times the Fed raises interest rates before the Z06 comes out.
The standard exhaust looks so much better than the goofy ricer inboard setup. Next, remove the hideous airfoils and you have yourself a very attractive car.
