Just bought a 2017 Z51 after 500 miles I started shopping around for exhaust systems. You just changed my mind and saved me some money. Thanks broski
Cool! Yeah it gets a little louder after it breaks in too.

Just got my ‘19 C7 Stingray, appreciate all these amazing videos and tutorials you’re throwing our way!!
Thanks for watching & congrats! Glad you found the channel!
really nice camera work. very well thought out. thanks
Thank you!
Thank you. I just got my 2014 stingray today. Thorough video. Kudos.
Thanks for watching and be sure to check out tons more C7 videos on the channel!
Great vid as always keep them coming !!!
Appreciate the support man!!
This is awesome. I have been looking at thousands of $$ after market pikes, but wasn't really impressed for the money, your meal replacement certainly satisfies the hunger. Thank you!
👍
On my 2014 stingray Z 51 it was fuse number 41. Thanks it worked!
Cool yeah it varies based on model year. Hope you check out more C7 videos on the channel!
I did this Mod on my 2014 Z51. Made a huge difference in the fun factor of driving my car. I was thinking of getting an upgraded exhaust from Borla, honestly... no need with with this little mod. Car is nice loud and throaty all the time now. Thank you for showing me this! =)
No problem man and be sure to check out my Mild to Wild video!
I’m buying my first corvette Friday! 2018 z51 , I’m pretty stoked , I’ll sub for tips cheers
Great work..I tried it and love it..the valve actually open when the RPM is over 2500 and when I pulled the fuse off the valve stay open all the time😍
Thanks, yes it makes a big difference!
Cool I just got my z06 and it sounded great but it kept closing now it will always sound great. Cant wait to get off work to home and try it.
Right on enjoy it!
thanks 4 the info. I'm buying a 2017 gs hope it's the same fuse
Nice, it should be!
thx man, just got a used 15 convertible, its a base model without z51 exhaust so its super quiet unless you really step on the gas..its a ton of fun but i find myself speeding to hear it..lol
Time for an upgrade :) You can find aftermarket ones louder than dual mode.
Nice Mod, I've told many of my customers about this. Thanks for sharing
+KCG Motorsports Welcome!
I admit that was a common sense question, but the only foolish question is the one you don't ask. Thanks for the informitive video.
Pulled the fuse sounds great. The drone is barely noticeable. Thanks for the tip. I had the selector set for sport when I pulled the fuse.
+David Thomas Nice! Don't forget Eco mode as well on highway will quite exhaust when running on 4cyls.
CarGuy11 Ok man, and thanks for the videos.
This was the best video I've seen on this topic. It's been so frustrating reading forums and other videos say, "Just use Track mode in the menu screen!" and completely fail to acknowledge that even in Track mode, the valves still close at low RPM. The difference is real though 👍
Appreciate it man & hope you check out more great videos on the channel!
bladed????
Thank you sir.
Thanks for the tip! The wife noticed the difference!
No problem & hope you check out more C7 videos on the channel!
Awsome I will be trying that tonight
Cool!
The 4 exhausts in the middle is so cooool
Yeah and when valves are closed for quite mode, the outside 2 are blocked.
I am doing the mild to wild because you can program stealth default and change to loud using your homelink buttons
Yes lots do this.
Just got a 2014 Stingray Z51 3LT. Thanks for listing the proper fuse to pull for this model year. What a difference.
+Simon Lindsay No problem man! Thanks for watching and congrats!
He didn't. It's fuse #41 for 2014. Fuse #42 for 2015+.
Thank man. Going to definitely try this on my C7. It is Laguna Blue like yours! :)
+FOneFan Nice thanks for watching!
CarGuy11 quick question, is the 4 cylinder mode a lot louder with the fuse pull or does the secondary valves make it near silent? Hard to tell on the video
+FOneFan Yes secondary valves take care of bad sound.
WARNING! The fuse does not just operate the exhaust valves. You will also effect other systems in your vehicle. It will not activate warning lights on your dash because those are only for critical system failures (that's why some people call them idiot lights for those who don't do routine maintence), however when you run computer diagnostics you will see several system errors within the driving components of traction control, differential, brakes, etc.
Where do you get your information?
Somebody betta' tell 'em...
That's not a good idea just to have a good sound. Stop being cheap, Get an exhaust mod, they're not that pricey....especially for a car like that...🤔
@CarGuy11 these guys are idiots 😂
Ur the man
thanks man
Ahh I can't get over how good the C7's sound. I hope to be able to buy one pre-owned when I graduate from college 3 years from now (presumably with a good job). I'm hoping they'll have depreciated by a good amount by then.
Yeah the mid-engine C8 will be out by then and C7s will be decent priced :)
CarGuy11 yeah I'm really not happy about the mid-engine decision for the entire C8 platform. I was really hoping that only the special edition will be mid-engined. I made a vlog talking about my thoughts on it
I know I watched it. I have mixed feelings, if they are going to price it close to C7 I'm ok with it. If not should be Caddy to compete with exotics.
CarGuy11 I agree although I doubt it's going to Caddy because they just invested so much money into the Chevy factory at Bowling Green. If the price stays around 60k for a base Vette then I'll be happy
Mine went up
Thanks man!!!
Welcome!
damn... you can actually see the torque
Haha
If you go to sound engine management and you just have to switch it to track and it opens up the exhaust so it is at its loudest at all times
+Roman Angelo As shown in the video flaps still close at times even in Track.
I just removed the fuse today and wow what a difference
Great! Just but back in for a long highway trip.
I enjoyed your video. Thank you. Now If you can make one on how to afford a C7 in todays market. That would be awesome. 2014’s are asking $60-55k. CAD
Hi
Thanx for a great video as usual.
I have 2 questions
1- how did you add those gauges on video ?
2- how to disable eco mode
I have 2019 z06 MT
Thanks for watching! I use TrackAddict app on phone for gauges. 4 cyl mode is disabled in all driving modes except ECO with manual. ruclips.net/video/yIqUHl__Ric/видео.html
@@CarGuy11 You are the best bro. Keep posting we love your videos
Thankz Mucho for that! never liked the way the exhaust note goes away at low speeds ... love the sound of V8 rumble! maybe now I won't have to go so fast just to hear it...well...maybe 😏
Haha glad to help! Thanks for watching and hope you check out more C7 videos on the channel!
awesome vid,,damn you must get tired of answering the same damn questions cause ppl just dont listen or read replies,,lol
Haha yeah no one believes the valves close in Track mode.
I was able to keep mine open all the time on my 2015 Z06 through my tune, but good stuff if your C7 is stock!
+OG Kronix That's awesome you can control with a tune! Good to know in the future! Can you still put on quite mode if you want?
No quiet mode with my tune, but I'm putting down 900+ rear wheel HP. Headers, cammed, bored, new pulleys, exhaust, the whole 9 yards. But on my first wave of mods when I still had the factory exhaust, that's when we did the override for the mild to wild exhaust.
42. The answer to everything 😂😂😂
Hi, great video! Will this work for a base 2019 stingray 1LT with no performance exhaust option?
Thanks unfortunately no it won’t work on standard exhaust.
Hey great video, just pulled my valve2 fuse 42! Question the manual of my 2015 basic says valve 1 is fuse 32, so I pulled that one too. Can't wait for the rain to stop so ai can test the sound...
+Jim P Valve 1 is the 4cyl mode valve and it will cause check engine light with that fuse pulled.
I think there is a setting that will allow the loud exhaust all the time without pulling the fuse. It is in Settings, Driving Mode, Engine Sound Management, click it off. Loud all the time.
No still closes at times as shown in video.
ok thanks
that’s funny. i did the same thing on my c6 and ran it without incident for ten years that way. on my 2014, the fuse is number 41. not 42. fuse 42 in my car is a 10 amp fuse for the reverse lockout and #41 is the 20 amp exhaust flap fuse. perhaps the legend printed on the inside of the fuse box cover was printed wrong. or maybe they made a change. my car is an early 2014 premiere edition.
Yes 2014 is fuse 41. All other years fuse 42.
CarGuy11 thanks for the clarification!
Very helpful vid, CarGuy11 and very helpful info, Mark Morse. I have a 2014 Z51, so you just made my life a little easier and my fun more funner --- Thanks!
Glad it helped!
Pulled the 42 on my 2016. Much louder and with with the Range AFM defeat device on, valves never close as the 4 cylinder mode is disabled. Love it, makes a racket but still pretty quiet when you’re not on it.
Hey CG11 just watched a video that shows you can go into settings and set exhaust on track sound at any drive setting. Is this different than what pulling the fuse does. Doesn't look like it.
Yes, even in track mode the flaps close at certain Speed/RPM as shown in video. Only pulling the fuse keeps them open 100% of the time.
I'm assuming this will work in my 2016 Z06? I hate when it gets quiet! I drive it in Sport mode only.
(If it will work, is it still fuse # 42 on mine)
Just FYI: My dealer told me (for whatever it's worth) that Track mode is reserved for the track only. Driving it Track mode can "damage" it if it's driven on the street...Don't know if it's true, just what he said...
Yes should work the same in Z06. Dealer was talking about track suspension mode since its possible to bend a rim with the stiff suspension going over pot holes.
Do I get lower mpg when I'm using track mode exhaust even when I'm driving in your?
+Roman Angelo Not when you just turn sound setting to Track and not drive mode.
Good, thanks ..:)
Welcome!
Really work...:o)
My question is is there more crackle/ burble in the lower gears when you accelerate and then let off? I drove a C7 with the AWE touring exhaust and it did this and it sounded so nice… If this doesn’t do that I’ll have no choice but to just swap out the axleback… I’m my opinion that’s how a corvette should really sound like
Yes you will hear more burbles when the valve is open.
Great find! Will this work on the 2014 C7 with performance exhaust?
Yes but it is Fuse 41.
Yes its fuse 41
Pulled fuse 41 on my 2014, didn’t notice any diff. It still closes and opens. Going to try and unplug the valves at the rear next.
Might be different fuse on 2014.
So do the valves only stay open when in Track mode? The valves won't be open in touring mode right?
Track is mostly open except for times shown in video. Tour opens up at higher RPMs.
Good sir, do you know why my flaps are NOT opening whenever I pull the fuse…that should default them to stay open always. I have a 2013 Grand Sport. Thank you!
It’s likely a different fuse # on the C6 so you will have to look it up.
Have a 2014 C7 , it shows 2 fuses , left and right exhaust and I want to install the mild to wild kit , what fuse to replace
+thomas goellner On 2014s its fuse 41.
I did this pull the fuse trick on a standard C7 exhaust a later on a had a code appear. Took it to GM dealer and they said the fuse also involves the emmisions system. Reinstalled fuse and no more codes.
That's because those were the 4cyl mode valves. Those will cause CEL. The dual mode valves will not.
i have the same car..pulled fuse sounds louder. lots of carbon on the outside tips. but nothing on the inside ones as if they are not working lol... is there another fuse or somthinf i can
The inside tips are used when the valves are closed because they go through the muffler which is more restriction. So not much comes out of them when the valves are open.
I know I am late to the party but I just got my 2017 GS. Can’t you disable this in the settings menu as well? The setting is called “Engine Sound Mangement”
Yes but even in Track the valve still closes at certain times as shown in video. Welcome tons of C7 content on here for you!
On a 2016 Stingray when do the valves close if in Track Mode?
As shown in the video, valves close at certain RPM/speed even in Track Mode.
Hello! Thanks for the great video. Was wondering if this works for 2019 Base model stingray 1LT
This will only work with the NPP performance exhaust option. Thanks for watching & hope you check out more great videos!
Regardless of the fuse being pulled the exhaust varies... Values don't stay always Open
With the fuse pulled, the only valves that can close are the secondary values when running on 4 cyl mode.
Did anyone else notice fuse 32 said exhaust valve 1?? What’s that one for
That’s the 4 cyl mode valve before mufflers.
So after you pulled the fuse in economy it will still be quiet? the same for tour and weather mode?
+Okaythen001 Yes when it goes into 4cyl mode.
just found out about this, any issues come out yet since this was a year ago
Nope no issues.
All C7 owners, read your manuals. #42 is a blank on 2019 . It is fuse 87 for the 2019 model!
Thanks for the update!
fuse 87? forsure?
My 2014 Z51 had Borla Attax already installed. Do they have the Fuse 42 connected as well?? Thanks
If it has a valve that opens & closes then yes.
Hi! Do you still drive without the fuse? Any concerns about not having the fuse in the fusebox? I have a -17 GS M7.
Yes I use MildtoWild switch. No issues running no fuse. ruclips.net/video/PYgidQ2Xke8/видео.html
@@CarGuy11 Thanks a lot for quick answer. Have a great day Sir!
I feel like what’s more important about this “mod” is that before, when you start the engine it sounds very dull and after when you start it, it sounds much better
It will stay in Sport Mode even after you turn off so that’s how you get loud start stock.
Will it stay in track mode? If so how? Because mine goes back to touring every time
@@nightghost7755 No unfortunately just Sport. Also you can manually set exhaust mode in settings & use M2Wild switch. ruclips.net/video/PYgidQ2Xke8/видео.html
So I can set it sport in the sound management so when it starts, it will start in sport??
Is that correct?
I have a 2016 z06. Didn’t seem to do anything for me. Sounds the same as it did in track mode.
There are times the valves close even in Track mode as shown in video. It doesn’t get louder just keeps valves open all the time.
Will you still be able to use 'stealth' mode after pulling the fuse? Worried about neighbors when parking at night
No but you can use Eco Mode which will close afm valves in 4cyl mode. The other option is get a Mild to Wild switch like I installed. ruclips.net/video/PYgidQ2Xke8/видео.html&t
Can this be done without pulling the fuse? What about Sport mode & the engine sound management settings or is this only for Track mode purposes?
No the valves still close as shown in the video. Another option is getting a MildtoWild switch as I installed in this video. ruclips.net/video/PYgidQ2Xke8/видео.html&t
CarGuy11
Ok thanks. Good info. 👍
Just bought a 2014 Z-51 3lt white red interior with 5400 miles on it was wondering if pulling fuse 42 is still safe for car for better sound?
It is. However, you need to be pulling fuse #41 for your year.
I'm confused, you said you were in Track mode, but it looked like a white T with blue background, meaning Touring mode.
You can manually select the exhaust mode in the settings menu regardless of driving mode. ruclips.net/video/Mk1DX2M2iG8/видео.html
will the valves remain open after i do this , and im on tour mode? i dont like driving on track all the time lol
Absolutely the values will be open at all times.
hello, just saw your video. What is your opinion on muffler delete instead. I am not sure which way I am going. Thank you
Wow that’s really loud. I wouldn’t because of the drone.
Thanks for reply. I am going to pull the fuse.
Looks like you have it in Touring Mode not Track Mode? In Touring Mode the Valves will favour being closed more then open, I drive around in Track Mode when I want a more audible permanent exhaust note.
I show in the video how the valves still close at times even in Track Mode.
What happens if i remove the fuse for the secondary value?
That will cause CEL. Also it won’t improve the sound since only active in 4cyl mode.
Thought you could do this under Settings?
No even in Track mode it closes the valves at certain times as shown in the video.
hey man there is a feature in settings to set it up to run on track valve settings without pulling the fuse. Is that the same thing?
+Derek Isakson No they still close at certain gear/speed for noise regulations.
+CarGuy11 yeah I got it now. I did it and noticed it. Cool tip my mans.
Hey CarGuy11, in the video your Corvette symbol is on the media screen the whole time....how did you set that up?
It’s the screen when radio powered off (press and hold power button). This was a 2016 change.
CarGuy11 Thanks so much, I have a 2015 so no luck for me lol
Will pulling the fuse out void your warranty in any way?
No it won't. Plus you can put fuse back in when taking to dealer.
Would this work '17 grand sport?
Yes it will!
Will it work on a 2019 z06?
It should. May want to check fuse block to be sure correct number.
does the car have to be warmed up in track mode before I pull the fuse haven't drove mine in a while here in ohio with bad weather I'd like to pull the fuse out right now will it open automatically one it starts
+15blkRR Yes make sure valves are open in Track or Sport mode before removing fuse.
Have you ever driven a Z06?
+Connor Pitisci No but I need to.
What does this do to the car does it affect it
Prevents exhaust valve from closing. It’s safe to do.
what year is that ? i have 2014 the fuse box different
+Joseph Kidd On 2014s its fuse 41. Mine is a 2016.
FYI, You reinstalled the fuse box cover wrong, need to flip it 180*
He’s a Putz’
Is the code still 42 for a 2019 model? Or is it different?
Someone posted fuse 87 on 2019.
Hi bro there is another exhaust valve fuse which is 32 why didnt you pull that one ? My cts v has 2 exhaust valve fuses but which one do i need to pull ? Its 35 and 38 and im confused actually maybe its the same way you used to choose and thanks
That is the 4cyl mode valve only used during 4cyl operation which wouldn’t help sound. Plus you will get CEL by removing it.
CarGuy11 thanks man
how do you put the corvette flag on the stereo like that?
Just press and hold power button until completely off. It may be a 2016 change though.
hey what will happen if you leave the fuse pulled out too long? any negatives ?
No but may want to throw fuse back in every few months to keep the exhaust valves moving so no chance of sticking.
0
i have a 2014 z51 with nav....can u change picture on nav screen?
No this was a 2016 change.
Damm.so no way to customize?
How do you keep the corvette logo on the screen ?
Thats with stereo off (press and hold power button). It was a 2016 change.
My 2013 Grand Sport will run the Cross Flags on screen too when I shut the radio off.
Our '14 has the option of a blank screen or the clock...and its a BIG clock lol!!
Or add the Mild to Wild switch
I'll
Just put you exhaust
In Track Mode and use Sport Mode steering.
Great videos! The vehicle you are showing has dual mode exhaust? Suppose we have standard exhaust (not dual mode) if we take out this fuse will it greatly increase the sound of a standard exhaust?
+The Man The standard exhaust doesn't have those valves so already full open :)
can we pull the fuse those and make the standard even louder or can pull it? also what is your opinion of the standard exhaust, not the dual mode. Is the standard pretty rocking also? or dead?
No there is no fuse for standard exhaust. It sounds like performance exhaust in Stealth Mode. ruclips.net/video/Mk1DX2M2iG8/видео.html
Thanks! Do you personally think as many others indicated the standard exhaust in Sport or Track mode is pretty nicely loud and intense?
The standard exhaust does not change sound in Sport or Track modes. It's like driving the performance exhaust in Stealth mode. So quite all the time and I don't like that. Get the performance exhaust or plan on getting an aftermarket one.
I wanted to do this. But the grand sport 2019 doesn’t have this...
It’s probably just a different fuse on 2019. Just look under lid to find exhaust valve fuse.
whats the fuse # for a 2017?
Should be same as 2016.
Does this fix the v8 to v4 problem?
No it will still go into V4 if you have an auto.
When i removed the fuse on my z06, the car wont go in drive. I tried multiple times and it still stays in park. Do you know the problem
It may be a different fuse # on your car. Check the map on lid for correct fuse.
What would happen if you unplugged valves? they would stay open always?
That is what pulling the fuse does. Valves stay open always.
NOT TRUE ..... they still open and close. I want the valves to stay open always 100%
No the only valves that still close is the one for 4cyl mode. The rear valves stay open as shown in the video.
Question: Does this mod work on a 2017 Camaro SS? Same fuse?
Yes it should but didn’t know fuse #.
@@CarGuy11 OK, Thanks.
