F430 headers

Sounds like a great deal. I have fabspeed headers on my 430 and have no complaints. Of course I'm not as technical as some of the gurus so I can't testify for gains brand versus brand. Just a happy customer.

 

Having just read back through this thread I can now see why the difference in Dyno results... although can anybody explain to me what exactly is meant by "disconnecting the valves"?
Does this mean they're permanently open or permanently closed? If closed then that doesn't quite explain how the 1st run still achieved the same power at maxxy whizz?!?

Anders, I can see that you had the Fabspeed headers fitted before changing to the capristo setup, what led you to that decision? I'm highly interested in buying those off you right now but obviously I'd like to know what made you decide to change and how long you were using the Fabspeed ones...

 

Aaron - disconnect valves means always open exhaust. Just take the tubes of the valves and seal them with a screw or something. Now you will have a louder sound even at idling.
The exhaust is now not going through any silencer at all. Just the pre-cat in the manifold and then the head-cat.

I send you a PM tonight and discuss the exhaust parts I have for sale.

Ah. I see. Well I intend to leave the setup just the way it is, I'm only changing the headers to sort this cracking problem out anyway as a preventative measure so that's all I'll be doing... Oh and I'm now doing those Diode light upgrades from Ikea... haha they look fantastic I, along with everybody here I'm sure, am well impressed with the result and intend to get right on it!!

 

Has anybody just installed the upgraded brackets (Capistro or Fabspeed?) to the stock exhaust to avoid future breakage? How much are they and how involved is tha swap? Curious. Although any such failure seems to be covered on 430s for 8 years, but it sucks for owners with no Ferrari dealership anywhere near. Thx.

 

I had done that. The Capristo ones. Expensive, but clevere engineered. Recomend to do that if you don´t do anything else.
Have this set for sale since I got a second one when I changed all exhaust parts to Capristo.

/A.

 

I've got the capristo mounts on my 430. Superb stuff. Won't cost yuu more than usd$350 to get them. Cheap as chips and well with the money.

 

The Capristo mounts is a "must have". The stock brackets will make your headers fail as they are holding the entire exhaust line too tight. I just discovered that my stock upgraded headers start leaking a little bit. When you start seeing a typical metallic dust on the rear window or on the upper engine parts, it's the first sign that the header internal insulation material starts getting away. At the cost of the headers (which isn't under a 8 years warranty in Europe), 350$ is bargain

 

Is the same true for 360s?

 

Stupid question from me and might have been asked a gazillion times before...but are the o2 sensors at the cats where most replace with a test pipe a narrow band or wide band sensor?

 

How do you know if you have a problem?

 

PM sent.

Thank you both for your help; greatly appreciated.

 

You had my PM plz......Thanks

 

Anyone have the part number or reference for the Capristo mounts?

Got em, thanks!

 

I just ordered the capristo exhaust brackets... I still have the stock headers I will see how things go with just the brackets then decide if I want to do the headers later on. But if I do decide to do the headers I will do the capristos I have heard so much about them and I really like the heat sheiks blankets that they offer. Has anyone on here don't just the capristo headers with stock cats and muffler? If so what are your thoughts?

 

I might have misunderstood the question, but I will be doing just the headers and leaving the factory cats, silencer, and tips. Getting rid of the factory headers will:

1. Increase horsepower by a small amount (not a primary reason for me, but I will take it)
2. Increase the volume of the exhaust by removing the pre-cats, the increased diameter of the pipe and collector style.
3. Change the exhaust sound toward the F1 tone, per comments in (2)
4. Reduce the chance of catastrophic engine damage in the event of a header failure. Mostly because the removal of the pre-cats will allow any debris to be blown downstream where it will somewhat harmlessly be trapped on the hot side of the main cats.

 

Don't they also give you a very significant increase in torque at low RPMs? To me that is the most compelling reason to do it if it's true. Anyone have first hand experience?

 

Feel free to review the dyno graphs from fabspeed and capristo. [both appear to be base 430s]

But yes it looks significant in both cases. @ 3750 RPM Fabspeed is showing +88 TQ, Capristo is showing +~50 TQ. I dont wish to discuss the delta between capristo and fabspeed, but will agree that at low rpm (untuned rpm range) both show a significant and probably butt dyno perceivable increase in TQ.

What would you do if ferrari gives you the new headers under warranty? Keep them and get new exhaust or get new headers and sell the new headers ?

 

Install them along with Capristo exhaust brackets.
