That's a good approach but I'm still happy with the forza

 

try this one

Has anyone tried just unplugging the solenoid to leave the valves open all the time? Does it or does it not throw a check engine light?

 

I think a few have removed the vacuum line and capped it with no codes or I'll effects.

 

Based on my experience with my Ferrari, you could probably get away with with unplugging the solenoids as I did on my 360. It does not throw a light. The valves will still be "connected" to vacuum though and you may hear some rattling until the valves warm up. But they should remain open since they do not get a vacuum supply when solenoid is "off." They have to be closed electronically afaik. But the ecus and software may have changed since 2004.

 

As long as you disconnect the vacuum hoses from the vacuum solenoid valve to the actuators on the bypass valve ... you will not get Check Engine Light or a trouble code logged. But, when you do this, plug the vacuum hose end ... don't leave it open or you will have a massive vacuum leak. Also, suggest you get a small bit of vacuum hose to leave connected to the nipple on the bypass valve actuators. Plug this bit of hose as well. This will keep road debris from getting in which could damage the actuator diaphragm over a long time. For plugs, you can use a golf tee, a threaded fastener or ... the best thing going ... a small plug from Home Depot used for plugging 1/4" drip irrigation lines.


BTW .. DO NOT disconnect the electrical connector from the solenoid valve. This will cause a check engine light. Not on the Ferrari 360 ... but it is an older car.


The down side of this ... the valves will always be open ... and no ability to toggle between open and closed.

Forza Steve shipped me the new E3 controller for my QV. Installed and works amazing. So nice to hit the homelink button at any time to open this bad boy up!!!!

 

My experience as well. I have never regretted this mod. Because of lack of time I had my local muffler shop do the install. The said it was a b*t#h and charged me $160.

 

look at the post above, just cap the vacuum lines. I did on mine and there are no issues of any kind, and just simply plug the lines back in to return to stock. just cap the hose as well as the solenoid to prevent any moisture from entering. Took me all of about 10 minutes to do.

 

Although I make and sell the Forza controller for the Alfa, I always recommend that owners try the method of plugging the vacuum lines to see if that easy mod suits your purpose. If you are happy with the valves open all the time and would never anticipate reverting back, then that is a good way to go. Only get the controller if you want to toggle back and forth.

I love the Forza, and am glad to have the option to turn it off should a passenger nag me enough into doing so, but my only worry is that a large enough bump on the road, coupled with a firmer suspension on the qv could knock it loose.

My installer was able to file down the cross pattern under the fuse box so all of the adhesive pad (and it is a large pad, looks about 10x the size of an ezpass one) sticks to the bottom of that compartment, but I still worry it could come loose. @forzasteve have you encountered any issues or heard of anything?

 

I have not had anyone get back to me stating that this occurred. The specs for the 3M Dual Lock fasteners is that it will hold 20 pounds per square inch in vertical force (much higher in sheer) and is temperature rated up to 220 deg F. With your kit you have about 4 square inches. So, even with somewhat uneven surface, I expect there should not be a problem. I have Ferrari 360 and have secured the controller, to the underside of an engine bay panel ... been there for over 3 years and no issues. That is a more severe environment than on the Giulia.

I have some people give me feedback that they used cable ties or other means to wrap around the controller body and then secure it to something. Not on the Giulia, but on other cars such as Ferrari. If you have a concern on your Giulia, I expect that you could use this technique or perhaps a long piece of stainless safety wire to secure the controller in place. Safety wire might be good as it is very thin and would only require the smallest of openings to thread it through a panel.

Best regards,

Steve

Had the Forza Exhaust Controller installed today! Love having that sweet exhaust note while still having traction control.

 

I think the only issues a dealer could reasonably argue the controller damaged is possibly the exhaust valve solenoid failing itself or if something got shorted out during install. They can’t blame it on much else realistically...

 

I have a June 2017 Build date but only 1700 miles. No mods no track hoping that I don’t see the same result. How many miles and also what are you pursuing replacement or buyback?

 

I have 16K miles on her, but the issues started at 4K miles.

 

So for the buyback do they put you back whole or if you go for replacement find you a comparable car with 0-4000 miles or a 2019? Not sure how they do that. Should be interesting.

 

in my case as the car had under 500 miles when this all happened I was getting a check for the full purchase price & sales tax. They could not get me another RC/Blk QV as there were none in country at the time and I didn't want to order one and wait.

 

The stock Quad muffler has two pipes routed into the can; the vacuum-assist only opens the outboard pipes in Race mode. The Stradale system is a legitimate straight pipe set-up in Race mode.

 

Hey everyone! Bought a 2017 QF 2 days ago and loving it. I’d like to open up the exhaust sound. I bought a drip irrigation 1/4” valve at Home Depot. Now I need that silicone 1/4” line right? Can someone point me in the right direction please? HD and Napa were no help.

 

The controller really works well but since you sound like you're going the manual route, try this link

BOM that I'm going with to do two cars.

 

Thank you! That helps. I’m in the San Diego area. If anyone used a shop here to do this on their lift lemme know.

 

I think I'm going to try this mod this weekend.

 

It's a must have for the qv!

 

Just got my from Forza, will put it in next Thursday at the Dealer.

 

Hope the mountains hold their ears....

 

All right ladies and germs, I had my local dealer (SD Alfa) install the 50 cent irrigation valves K01N told me to purchase on amazon. They didn't even need zip ties or silicone tubing - they used the factory tubing they had laying around instead. And they charged me $0.00.

I can't understand why didn't Alfa just build the car with the flaps open? It's not too loud. It doesn't drone. It's wonderful. Go get it done! No Forza needed!!!

 

There are a few countries that require whisper quiet cars. It's easier to have a one-world car. I think Switzerland is at the top of this list.

But, the other differences between Euro cars and USA cars don't support this one-world car theory.

 

Yeah I just started to use the Forza after getting it installed earlier this week and find myself just opening up the exhaust all the time. That said it’s nice to be able to quiet it down when you want to drive through some sleepy towns that like to pull people over and to quiet it a bit when on the highway cruising. Having the Homelink programmed to open and close it make it super convenient and always just a button press away!

 

I just bought this but it wont start up in open mode. Anyone know how to fix this? everytime i start the car I have to manually switch it to open mode to hear the full exhaust

 

I think you have to enable it every time you use it. The new revised model does remember your last setting I think...

 

Which one is the revised model? I have an e3 model I just bought it from madness

 

The E3 should be the most current ("best" on Forza's chart). http://forzacomponenti.com/faq_compatibility.html

It seems the B4A allows you to set it always open.
.

 

From forza’s vender thread:

Model B4A Exhaust Controller. This controller has the enhanced function of having a user-defined default state ... that is, the use can configure the controller so that on engine start the controller will be in Normal mode (the car's ECU manages the bypass valves) or Always Open.

The Model B4A cost $360.

The Model E3 controller does not have this option, however, it cost $295.

Now Alfa Giulia QV and Stelvio QV owners have a choice of controllers.

if you don't want to add the valve or cut the hose, you can simply pull the tube off the actuators and cap those and the tubes and then zip tie the tubes so they don't dangle

Thank you! Exactly what I was looking for.
