Make sure the exhaust setting is not overridden in the driving mode settings

It’s quiet in there for sure. Until you go WOT!

long tubes will change your mind significantly.

Long Tube Headers will require you to tune, and once you're tuning, you might as well do an intake and pulley. And at that point, a serious pulley upgrade will require Meth or E or both, so might as well do that, and now you're looking at possibly Heat Exchanger upgrades and hey the blower's off might as well port that and the snout too. That's certainly a way to get your exhaust louder, but it's a different path than a typical axle back/cat-back system.
I personally would recommend a cat-back change. Have you seen how ugly, big, and heavy the factory Cat-back is on these cars? I dropped mine off in one piece and replaced it with a Borla 60606 X Pipe and Corsa Xtreme axle-back and the sound is to die for. MUCH louder on start up and wide open throttle, ear splitting in the tunnels/next to concrete structures, but calms down and cruises nice and quiet. But as soon as you drop a gear, it screams. I started my C7 Z06 and ZL1 back to back when both were stock, the ZL1 is loud and is a bit sharper on initial start up, but the C7 Z06 is just a bit louder on startup and stays louder once idling. By the way, the fuse pull is really a dumb idea on these 5 mode NPP systems. You might as well put it in track mode and at least be able to show your buddy how you can change the exhaust 5 different ways. |

Yeah, I think the ZL1 stock is actually a lot louder than many realize if you are only hearing it from the driver's seat most of the time. I've been outside and had my wife drive my car down our street and a few blocks away with some decent pressure on the GO pedal...and I can hear the car 2 blocks away! It really does sound pretty darn good outside the car stock. I know several on here have mentioned being flagged at certain tracks for being too loud stock as well.
That isn't to say that going even louder or changing the tone is a bad thing! Just trying to say that the car really is fairly loud stock. And as others have said, pulling the fuse does net you a bit more of the track model exhaust goodness more of the time. It doesn't make WOT any louder or idle any louder...but cruising and light acceleration is more noticeable for sure. I also get more popping and cracking from the exhaust during deceleration and downshifts. I pulled my fuse a couple weeks after I got the car and its been great. An added bonus is you only have to clean 2 of the exhaust tips...not all 4!

After years of having to wear ear plugs when I drove my track car I rather enjoy the exhaust!

My 6th ZL1 didn't crackle on decel like my 5th gen ZL1 did, maybe that's because of the Auto trans vs manual trans though. So there's not really any crackles now either, only once in a while if you're in manual mode. The downshifts are nasty. That said an exhaust change isn't going to make crackles stop or start. It comes from excess fuel in the exhaust. Change the exhaust and it still pops. It just might be louder or quieter.

A question of taste...

I think those that can't hear the stock ZL1 exhaust at all are stuck in Stealth mode or have some hearing loss. In Sport it is hard to miss. And I already hear the blower. I wouldn't mind ramping that up a bit.
I would not mind ramping up the sound a bit also if it can remain tame in Tour and 100% for sure no drone. It is just so silly expensive. $2K for a good 3" catback. Been there done that with LTs on the CA6 SS. For the HP it is hardly worth it unless you are going for big power. And the loss of easily going back to stock is a big one for me.
