Engine sound management chassis control module not installed
I have a new 2017 C7 Stingray with the 2LT and Auto transmission. The engine sound management on my car doesn't work. I've taken it to the shop. They just told me that it's not installed on my car. The "chassis control module" isn't there.
Correct me if I'm wrong, but I thought this was standard on all corvettes. My software even has all the menus and choices for the Engine sound management but it obviously doesn't work.
Do I need to send this car back to the factory and have them do it right? I'm kind of upset about this...

^^ I don't remember that being an option. I ordered a stingray (my first corvette) with the 2LT. the exhaust wasn't discussed. It was demoed to me that this was on all the cars so I didn't think to ask about it. They made it sound like it was standard.

No NPP, No performance exhaust. No need for a chassis control module to control what's not there. Sorry, the car is fine. The missing module is because the NPP was not selected as an option during the ordering process.

It's a shame that you didn't get it. Obviously a misunderstanding. I'm not sure but the aftermarket, like Borla, Corsa etc, make really good systems which are quite until you mash the gas then they actually sound better then the NPP. Much less expensive then retrofitting the factory system.

Sorry your order got messed up. Not having NPP is not the end of the world. The standard
exhaust system sounds the same as NPP with the valves in the silent/closed position. After accomplishing a test drive to sample the NPP system, I ordered another Stingray without NPP so I am ahead $2,400. I like the look of the standard system better than the large horns on the NPP (subjective).

OP, The NPP (Dual Mode Exhaust) is an extra cost option of $1195 on the Stingray Coupe and Convertible. It is standard on Z51 equipped Stingrays, Grand Sports and Z06's. Stingrays equipped with standard exhaust will still have the sound management on the screen but it is non functional. There is nothing wrong with your car!

My '16 Stingray Convertible had the standard exhaust and I had a Borla ATAK axleback installed. It actually sounded better than the NPP exhaust! The Borla ATAK axleback was $1250 with free shipping and $130 to install.

Thanks for all the replies. It turns out it wasn't ordered and it's not on the car. I'll deal with it... :-)
The part that really upsets me is that the sales person told me it was standard on all cars.
The part that really really upsets me is that the service tech that first looked at this problem, told me it needed a new chassis controller. They actually ordered it. I went back and they tried to install it. Says it's the wrong one and they'll order the other one. Tries to install that this week. The lead tech went over and looked at the pipes and looked up the build order and said it wasn't installed.
Enter one pissed customer. They had my car for a total of 4 days to fix a problem that didn't exist. Calls from the service manager and the sales manager apologizing immensely helped. They said they would actually look to see what they could do. I'm guessing nothing...

1st mistake...you believed the sales guy
2nd...you trusted the service techs
sorry to say unless you have a real Corvette enthusiast selling the cars or handling service you need to educate yourself or you will be upset more than not
thankfully there is Corvetteforum

The OP should listen to the sound clips on the websites from folks like Borla. I like NPP and had it in my C6, 2014 and now my Grand Sport, but IMO some of the Borla options sound better! The OEM NPP is designed for low restriction but the straight through Borla's in my street rod sound better. So did the Flowmasters I had in my modified S10 truck when between Vettes! They also did not drone at highway speeds like pulling the fuse on NPP.Would not waste my money trying to retrofit. Borla systems are not cheap but will sound better IMO. In fact if the dealer is really upset they should install the Borla systm free (assuming the OP buys it.)

If you want louder without spending big bucks, get a new X pipe with the small cat delete. Might be just enough to satisfy and it's only $400ish. I think there's options where you can buy the npp mufflers and manually turn em on or off with an aftermarket control module, at least there was with the C6.

I am sure that is frustrating. Some of the dealer I talked to that knew Corvette stressed the NPP option and told me not to order a car without it.
I think there are some good aftermarket options out there but you won't get the OEM integration with the sound management system. I am sure they could fit an NPP system into your car but I doubt the dealer will want to due to cost and complexity.

NPP exhaust is an option that your sales person did not explain to you. Sounds like you need to stay away from that dealership unless they are willing to buy and install an aftermarket exhaust for you since you were lead to believe one came with your car.

I read all the comments. Not sure where you live, or if you have more choices for dealers. But, besides at the very least two calls to you to apologize which is the right thing to do, it seems very clear to me this dealership is incompetent in both sales and service. I doubt very seriously you would have gotten that kind of rotten info from a salesperson who's one of this Forum's vendor/dealers. And as to the service dept/techs, the reason I wouldn't go back there is this isn't what anyone would term a simple mistake. They took in your Corvette to work on and had absolutely no idea what they were working on.
As to remedies, I'd suggest you look at the Borlas, Corsas of the world as your best and least-invasive alternatives. There's a ton of info on this forum in C7 General that will indicate where to find it, sounds, etc. Plus, there are some excellent vendors who will sell you the right parts and you can then begin the process of finding a good, indie shop to do the work on your car. Good luck.
PS I hope you find another dealer even if it's a bit farther away. Or we may see another story/recounting from you of dealer mistakes.
