Quiet sound at idle/low revs

Forza Componenti "B1" exhaust bypass controller. He's a vendor on Fchat too... great product at a great price.

Forza Componenti - Home

Far cheaper than a full aftermarket exhaust and achieves exactly what you're looking for.

 

I just bought one from them, haven't fitted it yet as the car hasn't arrived, really nice company to deal with though I can recommend, delivery was quick considering I'm UK based too.Part looks decent quality.

 

Leaving it in for servicing should be fine, if you're making a warranty claim on anything powertrain it might be worthwhile to remove it before taking it in. Of course it's all dependent on how mod-friendly your dealership is.
I haven't heard of anybody having issues directly stemming from the valve controller however.

Just buy it direct, I don't think he has any resellers at the moment. Capristo does offer a similar product, albeit at a much higher price point- that would likely be available through a UK reseller.

 

I recently installed the remote exhaust valve bypass on my 458.

 

My car has the valves open , it took 15 minutes at the Ferrari dealer and sounds much better.

 

20 minutes In the garage dropping the diffusor will be enough to take the lines off the exhaust valves and it sounds much better. No more on and off of the valves.

 

Yes. You can remove and plug the vacuum lines if you want the valves open constantly. With the kit, you can have the car act as stock also.

 

My dealer installed for me the Capistro version. It works great.

 

Doesn't require any parts. Just pull the diffuser and pull the vacuum lines so that the exhaust valves are open 24/7. I did this on my California and it was night and day. My Spider is so loud already that I've had 2nd thoughts about pulling the lines. Honestly, with a heavy right foot in Race Mode the majority of time and the top or rear window down, I can barely hear myself think.

While listening to CME lectures on my daily commute, I sometimes drive in Sports Mode with all the windows closed so I can decipher the medical jargon

My Ferrari master technician pulled the vacuum lines and left no paper trail to keep it on the DL from FNA. Free of charge. Surprising considering my dealership is mod-unfriendly. For example, they discourage aftermarket rims while OEM warranty is in effect.

 

Ferrari of Palm Beach did mine while I was purchasing the car last week. It's a 15 minute operation and sounds 100 pct better.

 

I asked my dealer to do this and they you lose low end torque and can cause intermittent stalling.

The low end torque loss I understand and it is quite negligible but I was surprised with the statement about intermittent stalling.

 

No noticeable loss of torque or a single stall with Cali over 2 years of driving with pulled vacuum liines.

 

The car will not stall w the lines pulled. As long as they're plugged. That's a joke.

I've read a lot about people saying there is "torque loss" with the valves open. What's funny is that the valves open at 2500rpm anyhow. Who measures torque or need torque from 0-2500???

The way the car is from the factory you drive along sounding like s complete goofball in town with the valves opening and closing.

 

Same here with ~ 9,300 miles driven on my 12 Italia with the Capristo remote valve opener.

 

Forza Componenti installed on my 458.
I attached it to the back side of the air box.

Indeed, and even a monkey can do it . Easiest way is with a pair of $0.10 golf tees ziptied away from the exhaust. Fully reversible in a minute. I MUCH rather do it this way than modifying the car with any aftermarket product, but to each his own. Good luck.

 

I had removed the plugs on my 360 Spyder. Someone had posted a very detailed step by step. The sound was a bit annoying though. The droning sound didn't sound "nice" I was loud but not good. I reconnected the hoses and bought a tubi. That was music. Does anyone have some detail on how to disconnect from a 458? I'd like to try it. I'm not very mechanical without pics. Thanks.

 

just remove rear diffuser, think it is 14 screws, will see vacume line at the back of frame going into a line that splits, and goes into the two valves, disconnect at that point, plug the two ends, and put diffuser back on. Makes so much different in sound and takes about half hour.
