2014 engine sound management vs. 2015/16

I'm referring to my 16 with NPP.
I don't want to hear what it sounds like driving by me, because no one else is driving it!
I'll try pulling the fuse, because I'm unimpressed with NPP so far, especially for the 1200 it cost me.
I want to hear this bastard from the drivers seat.

2014 has three settings for sound management
1) off. Modes don't change tone but Rear flaps still close under certain rpm/load conditions to prevent drone
2) on. Changes with mode.
3) fuse pulled. Rear Flaps completely disabled.
Front flaps are for v4 and will trigger an engine code if unplugged

UM, they've been "tame" sounding since they have been in existence...GM is very late to the party with the so so NPP exhaust they introduced a few years ago. In my opinion,it's not worth 1200 bucks when there are so many better sounding ones on the market... Don't know if they figure everybody who drives a VETTE is old and doesn't want a loud exhaust or they are just to cheap to ad a little gusto to the sound.... NPP is better then nothing,but not by much..lol. If you want a real kick,take a look at the stock C5 exhaust tips...there's a laugh ....
OP,are you referring to the dial settings?? My 14 3lt has T-E-S-TR....W...

I did extensive testing to document this. See posts 248 and 252 here: https://www.corvetteforum.com/forums...post1589742949

You can always just have an X pipe installed for a little more sound w/out doing headers or a tune. I loved the NPP sound (14, M7) and just ended up getting used to it and wanted a louder sound. I put on headers and an X pipe and had it tuned. Picked up a ton of hp and got the louder sound. The LT1 sounds quite a bit different imo than the LS3 did w/ headers. Maybe its the direct injection, I don't know but mine has a bit of drone in low rpm's (I did not have that on the C6) but is a very aggressive sound. If you want to wake yours up, you can go that route. An X pipe would be a fairly inexpensive way to get some more sound tho if that's all you are looking for.

Put LT headers on. That is what woke up my car. Like you, I found the C7 exhaust too tame. After headers, it is seriously loud even with NPP closed.
I had to pull the hatch carpet out to get some stains out. I drove it to work today and it was so loud, I got a headache. Carpet going back in tonight
