FAB-B Yeah they’re facing the right way, honestly it doesn’t matter which way they are facing. The pistons in you’re engine force the exhaust through your headers there’s no way air is going to go up you’re exhausted into your engine because the only valve open is the exhaust valve on that piston stroke and it closes once that piston reaches full extension. These people in the comments have no clue. Good install bro. 👍

You right exhaust has a flow

I guess it's pretty off topic but does anyone know a good website to watch new tv shows online?

///M !!

Thanks, did my best.

You're welcome ! Great choice of a car the 1971 Riviera, and great choice of engine as well !!! A coupe of valves will make that monster sound awesome. I'd be very happy if you could show me how it sounds when you'll have done it ;).

MakeFix fuck yeah boatail

MakeFix if u put flowsmaster do it right after the flowmasters so it will be like a turn down it will sound fuckin good and that muscle tone

Haha, I see exactly what you mean ;¬) !

Thanks Paul ! Glad you appreciate the video, it was a friends' car and I miss that V8 !!!

Thanks ! Yeah the sound was fabulous !!!

It's a great solution in my opinion, and should sound awsome on the XFR but not sure there is enough space to install this model.

Thanks, glad you enjoyed it ! It's not easy to share that awesome sound, especially when you don't have great material to film all that... I did my best though ;).

Thankyou, glad you appreciate it ;¬).

FAB-B 👍👍

Hi, great ! If you make a vid I'd love to hear that ;¬) !

Thanks Danny ;¬).

Cool, thanks ;¬).

Thanks ! You're not the first one to tell me that but they are not facing forward, I put on the right way but it's not easy to see where the front of the car is. Look at 12:03, you'll see they are open towards the rear ;¬). They were a little more expensive in France, like 80$ each.

I passed the wire through a small plastic funnel to avoid any wear and taped the wire so it wouldn't move, but thanks for your advice anyway ;). Indeed, it's not the most practical if you have to bolt and unbolt the cutouts to change the sound ^^, especially if you're in a hurry to hush up the exhaust ^^ !

Thanks 😉 ! I think you can probably fit it on. better to weld it nicely though, not how I did.

I made a video on my french channel to show more or less how I built it kzfaq.info/get/bejne/eK6elJiksLG3e3U.html 😉

I've added2 cutouts to my vx commodore before the cat,hoping nothing catches on fire

You're welcome ! It's the best of both worlds, the cops should leave you alone as soon as you close the valves ;). If you want to see how I did that pit I made a video about it, it's in french but at least you can see what it looks like : kzfaq.info/get/bejne/eK6elJiksLG3e3U.html

open exhaust on a V6... oh man, people are gonna hate you. lol in my high school days and a few after, I had a friend with a little ford ranger and he cut the muffler off. it was so annoyingly loud. but it was never difficult to find him when he was driving (pre cell phone era). his favorite thing seemed to be to wind that sucker up in second gear and then just let off. you'd hear the loud scream of his little 4 banger all the way up to, and just a little past the redline and then followed by a long crackling and popping of that exhaust. it was so damn loud and he just loved it. another friend of mine had ridden with him out of town some where, and it was late and the unsuspecting passenger dozed off. he woke up to the driver screaming about the semi coming at them, but couldn't see it from the disorienting tailspin they were in. it was all a joke. he had driven out to the old abandoned road where we'd raced the 1/4 mile to see how fast our parents' cars weren't. anyway, he noticed the guy sleeping away peacefully and thought it would be funny to scare the piss out of him. so he got up just enough speed to spin his little truck around and it worked. my friend, the passenger, said it literally scared the piss out of him, but he took it all in stride. it was pretty damn funny.

HAhahha ^^, great story :D ! I can really picture the seens ^^ !

Hi, thanks 😉 ! It was on a friends car and he sold it a few years ago but he didn't have engine light or other issues. I'm no expert but I would say that the further back you put them the better for reliability and confort, but I'm no expert. Depends also how much noise you want, the closer to the engine the louder it wil be 😅.

@@fab-b9818 thank you!

It doesn't block the flow to the mufflers but exhausts will mainly follow the quickest way out. I can't tell you how much gases come out of each exhaust but you will have 4 exhausts with the valves open.

I live in the south of France. You should maybe try and do it yourself, I had never done that before !

Thanks a lot ! Don't know how much space you have under the 2015 Mustang but you probably can, especially if you install them instead of the resonator.

FAB-B , the resonator is big and there a lot space, but my concern is that there will be excessive pressure in the center of the exhaust system, which might damage the cutout valve motor

Why would there be excessive pressure ? I don't think the motor will be damaged as the exhausts will always choose the easy way out, so if the valve is closed they will come out naturally by the rear muffler without much strain on the valve. That's how I see it but I'm not an expert.

Valves that I found on Aliexpress. One motor failed after 6 months but was replaced buy the seller.

Thanks, yes, with this system you can have them open anyway you want, although you don't have a precise indication of how open they are.

I put them correctly, but at some point it's hard to tell the front from the back😉.

It's not easy to see but the front of the car is behind me, so the exhausts are facing the right way (towards the rear).

Probably, I would'nt install them that close to the headers, you lose a lot of back pressure doing that and it's robably not good for the valves, but I'm no expert.

I didn't notice any leaks. Maybe you can put some high temperature grease on the sides of the actual valve so that it seals a bit more when closed, but I don't know if it will be enough.

I used empty spray cans which I cut, sanded and painted with high temperature paint ;).

I should have used some thread lock on the colar screws, and one motor stopped working after a few month but was replaced buy the seller. I found them on Aliexpress at the time.

Rae L what new California muffler law? I’m want to do this too.

Good question, it's more splashproof than waterproof I would say. You would have to find a way to seal the connections, maybe with a glue gun (but will it melt with the exhaust heat ?). The gears themselves won't really be a problem, although if flooded I would check them out and maybe clean and grease them again...

the electric motors themselves should be fairly waterproof, given the environment in which there intended to be used in. just water from road spray shouldn't be a problem, but a periodic check and a little spray of lubricant on the rotating shafts would be a good idea. now if you're talking a full blown immersion underwater, it might be wise to give them an inspection afterwards. should be OK as long as everything gets dried out. I'd definitely give them a shot of lubricant after an incident like that. you'd also want to check all the joints and make sure everything is still where it's supposed to be. I had a 1990 Chevy shortbed truck in high school and one night after a flash flood hit our area, I came around a corner and hit a lake where the road used to be. it was like hitting a soft wall. I was probably going about 50 mph and decelerated to about 10 mph in an instant. the force of the water hitting the Y junction where both exhaust pipes combined into one pipe right before the catalytic converter separated. the catalytic converter was yanked back several inches. the exhaust was noticeably louder. I liked it. but my parents made me get it fixed. that was a welded joint that the force of the water pulled apart. so joints that are bolted together will be much easier to break. just something to look out for.

Hi, what I installed are valves which do not modify the sound as such but simply allow the exhaust gases to come out before the rear muffler and that makes the sound louder. They are basically a hole in the exhaust that you can open or close. If you were to install them closer to the manifold the exhaust would be even louder and if you installed them just before the rear muffler it would be quieter (but still noisier than the standard exhaust).

Yup ,Thank you . I got it ! Please May you refer me to the link you have bought from AliExpress ?

The link has changed but you can easily find the same type of valves, they might even come from the same factory so just look for the right size and wether you want a remote or a switch, a part from that they're all pretty much the same.

Thank you very much and wishes you all the best !

You're welcome, thanks a lot :) !

I bought them on Aliexpress, but you can find them else where. It's a very good idea for the 350Z, I already love the stock sound of it but with valves, it will be just fabulous !

Not so much, I was expecting more.

Technically you can install that on any car that has enough space to fit the system. You will need to find the right reducers to adapt it to the car's exhaust.

Should sound pretty nice ;¬)

I can't remeber exactly, but I think I soldered them together.

I used empty spray cans (brake cleaner spray cans in my case). I sanded all the paint off then put 4 light coats of high temperature paint ;-).

+Anyone can do that ! How's it holding up?

With the heavy duty collars.

+Anyone can do that ! I meant like have you had any problems?

Oh, yeah it's holding up fine, and the owner is really happy with it, he drives almost all the time with the valves open ^^.

Thanks !

Anyone can do that ! I have a 2009 mustang GT and want to put the electric exhaust and did not know how, because I don't like is the part, after seeing your video I gave a good idea was brilliant your work 👍🚗

Great, glad to have helped you to see what to expect.

Empty spray cans (brake cleaner) wich I sanded and painted with heat resistant paint.

Haha thanks 😄. Didn't weld because I don't know how to and dont have the tools te do it !

It wasn't my car but the owner added a lot of Shelby features, don't know which are official or not.

@@fab-b9818 He should be happy with the car he has, and stop trying to make people think it's something it isn't. I've never liked people putting incorrect/fake badges on their cars.

Yeah I agree, but he bought it like that, to remove all that would have been probably worst...

I got them on aliexpress.

Clarence you can find these on American muscle

Demetrus Brown Yeah man! any car that has an exhaust lol. you just have to figure out what diameter the exhaust is. I'm planning on doing to to my 94 Ford mustang GT, as well as my 2012 Ford fusion

Exactly !

thanks guys

It's worth the money if you want to have both cars, the loud and the quiet one. Your neighbour qould be even more confused if the noise changed form one day to another ^^ !

Not if you use thread lock or something similar.

You noticed a leak in my video or on your installation ?

At your car when you started it ! 11:28 seconds of the video ....

oh yes, I see, it's a bit of condensation. Water can seep out but not exhaust gases. With time it will stop doing that as the heat shield fabric will sort of "clog up".

Anyone can do that ! It's been a year I think since you got this ...do you still have it ? Still working good? Just wondering since I'm installing the same kit it's 129 usd on eBay ..best regards from Las Vegas and nice video thanx

Yes they're still working well. It's not my car though but the owner told me everything is fine, and he still can't get over the sound ^^ ! PS: The owner of the Mustang is actually on holidays in Las Vegas as we speak, what a coincidence !

Yes, much better now 😀.

On aliexpress

FAB-B oh thank you god bless you

You're welcome !

I bought them directly from China so they were about 180 $ with shipping.

Anyone can do that ! m.aliexpress.com/s/item/32238265931.html?spm=a2g0n.search-cache.0.0.XemOlr#autostay

Anyone can do that ! is this the kit?

Yes, that's it. There are a few different ones but they are very similar, just make sure to buy the one you want, remote or switch.

I probably didn't buy the best quality blades...

The installation ? A few hours but I'm no expert.

Sorry I didn't make myself clear. I was asking if the valves are still working ok or did they last like some months. I hear a lot of people complaining about their durability.

Oh, sorry ^^, one of the motors stopped working after a year or so, my friend bought just the motor and replaced it. It's probaly not the best quality but the rest is ok. I didn't have the opportunity to check myself but maybe it was just a loose wire or something easy to fix...

Thanks for the information! I guess that's the average durability of these valves.

Yeah, it is quite a hot and hostile environment, more expensive valves probably last longer though.

Do that in CA and you get $1000 fine and it must be inspected by DMV to prove it was returned to stock before they will re issue a new registration.

David Anderson how do you know?

J'ai fait la même vidéo en français : kzfaq.info/get/bejne/gJODjLOdypqyiWg.html Ma chaîne française est plus fournie en tutos ;¬).

FAB-B merci beaucoup j'aimerai l'installer sur une BMW série 3 de 2013

Je voulais aussi le faire sur ma 330i mais il y a pas autant de place que sur la Mustang...

J'ai vu des vidéos qui le font même si il y a peu de place mais en faite j'ai peur pcq ça touche presque le sol enfin il est plus près du sol et aussi si ça passe le contrôle technique belge?

C'est ça le problème, parfois on peut les installer mais c'est risqué pour la garde au sol. Pour le CT je dirais que ça passe tant que la ligne est parfaitement étanche.

Not sure you gain something, apart from pleasure 😁 !

@@fab-b9818 hp gains. I’ve seen as high as a10hp gains.. it def feels like we’re going faster. I’ve heRd the exhaust is a restriction on these cars.. I’m considering doing a dyi cat delete.

Non don't worry, I didn't put them on backwards ^^. During the video I'm filming towards the rear of the car ;).

not that I agree with everything he did, but he was using the jack stands to hold the pipe up after cutting. they weren't there to hold the weight of the car.

Lololol

Yep, and it worked 😝 !

Thanks ! Don't worry, I put them on the right way, behind me is the front of the car ;) .

it's been modified by the previous owner but it's a 2009.

What do you mean ?

2003 Cadillac Deville..dual cam, 4.6L V8 not a Prius

George Wuertz laaaamee

Absolutely not, even though you can't see much from underneath. Look at 11:55.

hey, It was my first time !

I know lol I was saying your name
