430 Vacuum valves on Ferrari Sport Exhaust

Another F-Chat member had them, not sure where they were sourced from but they are the exact actuators. Tubi would be a good place to start I would think.

No, not the whole butteryfly/valve assembly that’s welded in, just the vacuum actuator itself. From an F-chat member.

Question did you guys have these issues from the time you did the install or did they develop over time? Getting ready to do a install this weekend

 

Mine was at the time of install

I finally got my rattles fixed. Ferrari replaced my complete sport exhaust system under warranty. I was told that if it’s been a year or less since your time of purchase, regardless of where it was installed, the part carries a one-year warranty from invoice date. Anyone with this problem should see their local dealer with purchase documentation. Ferrari of New England took the car in and sent documentation of the issues to Ferrari; they had a new system installed in a couple of days.

Mine had the rattles from the day it was installed. It was embarrassing, and I was driving with the valves open all the time to avoid the rattling, but it drones horribly at low RPM with the valves open. Very happy with it now working correctly. And I should mention that the reduction in engine bay temperatures with this system is staggering.

 

i just put the factory sport exhaust on my 430 that has cap headers and cap 200 cel cats. i literally cant tell when (if) the valves are opening...is it that subtle? on oem muffler its binary - you can distinctly hear when the vales open and close. anyone else notice the same thing our are my valves not opening?

 

TT, unplugging the vacuum hoses will let you know.

 

I wld but the car isnt here

 

ok thanks mike...i will have it looked at...
