One of the things I truly love about the new ZR1 is the exhaust sound. It has the "pops and crackles" on downshifts like my Jaguar F-Type and it just sounds meaner than the stock exhaust on my Z06. I'm wondering if there will be any way to put a ZR1 exhaust on the Z06 or is this system designed to where it will only fit the ZR1. Any info would be appreciated.

I'm sure it will bolt on and fit the same as the Z06 system. Not sure if it is the exhaust system or the difference in the tune that makes it pop and crackle like it does.
It does sound way awesome!

You know the ZL1'S do the same thing. Noisy little monsters! wonder why the ZO6's are toned down.

I have a 2018 Z06/Z07 A8 which pops, snorts and farts on decel as I downshift approaching a traffic light. That said, you've got to be in Manual mode, paddle shifting. Reminds me of my racing days. My wife loves the sounds, as do I.

Just happen to think, I have my exhaust in track mode at all times, regardless of the mode setting. In many populated locals running in wide-open exhaust will get you a ticket.

ADDED: My car is "bone stock."

Yeah, I was wondering about that as well with regards to if the tune was what made the ZR1 exhaust sound more aggressive. I'm guessing we'll learn more about this in the coming weeks or months as someone on here is bound to bolt the ZR1 exhaust onto their Z06.

MontanaBob

Z06s are not "toned down". See my response to the OP, BMadden.

Question, do currently own or have recently had any combination of the three (ZR1, ZO6, ZL1 )? The ZO6 does sound different. If you do, then you would agree.

Pulled the fuse on my Z06 (#87), and it definitely has a more aggressive sound plus the valves are open 100% of the time.

3rdgrey,

As I indicated in first post on this thread, my car is a "bone stock" 2018 Z06/Z07 A8 which pops, snorts and farts on decel. Here is my original post:

Dvilin,

Not necessary to pull the fuse. In your DIC, go to "Settings", "Driving Mode", "Engine Sound Management" and place the check mark adjacent to "Track". Exhaust will be wide open regardless of which Driving Mode you select.

DavidC83,

Assuming that you are correct, I've yet to hear the valves close in my car with the DIC setting that I suggest. From the moment that I light it off until killing the engine, my exhaust is wide open. Living where I do, one is not bothered by gendarmes issuing tickets for excessive noise, so I have my exhaust set in Track Mode 100 percent of the time, whether I'm in town or on the highway.

The advantage of using the DIC method is that, one can quiet the exhaust down quickly, without having to open the fuse panel to re-insert the fuse. All that is necessary is to reverse the process that I suggested.

U can hear the ZR1 and ZL1's on YouTube vid's. The stock sound as they track is comparitively different then the ZO6. Strange. It's possible individual vehicles have different sounds apart from the variable differences between LT4's and LT5's.

This is neat! I have not tried this particular fuse pull as of yet. I have pulled, I believe fuse #42, and notice a remarkable difference; however, #42 only keeps the last exhaust gates open. Therefore you can here when the vic goes to 4 cyl mode. I will have to try it out.

3dgrey,

As I've mentioned a couple of times, my car is a "bone stock" 2018 Z06/Z07 3LZ. It happens to be a coupe, which, according to several other threads bemoaning excessive noise in the cabin, I can't believe that I wouldn't notice the valves closing, even briefly, particularly if the exhaust sound suddenly changes from quiet to loud, or the reverse. That, in my opinion, would be very noticeable. One other item of note, mine is a very early model 2018, number 12, to be exact, but has been in the dealership a number of times providing many opportunities for the ECM to have been updated. Although, it is totally unrelated, I've had the MRC upgraded also.

FWIW, for the life of me, I cannot understand why someone would want to be mucking around in the fuse panel when the same results can be accomplished by changing a few settings in the DIC without leaving the drivers seat, but "whatever turns yer crank", as goes the ole saw!

Maybe to eliminate some confusion... I have not pulled the fuse, But...
There may be some truth to the fuse pull by many on this forum. My A8 in Track exhaust mode while in drive does go silent on occasion and my understanding is it is not the exhaust valve that closes but a flap or valve at a catalytic converter that causes the quietness and pulling the fuse eliminates this.
i am open to a better understanding.

Tort

If you don't pull the fuse, valves close at certain points under 2k rpm. If slowly rolling along, you'll hear the valves open at 2k and it's a noticeable difference. I run either with the fuse pulled or track mode for the engine management. 100% it is louder (at all times) with fuse 42 pulled.

dvilin

Just a quick note on the 2019 Z06 the fuse # is 87 on my 2015 Stingray it was #42. Not sure what it is for other years/models.
And one more last time no matter what mode you have your exhaust set in at certain RPMs the valves will close. Only by pulling the fuse will they stay open 100% of the time.

Thomasmoto

You should assume that he is correct because he is. Even in track mode/setting they will close at certain times.
You have to pull the fuse, or add a mild/wild switch to keep them open 100% of the time.
