Hi everyone, UK based Been lurking around the forum, really useful info used and bought my first Ferrari f430 spider in July. The manifolds were blowing so I decided to invest in a set of ap manifolds supplied by vivid. I fitted AP manifolds last week and it sounds awesome! Done a couple of drives since and power had increased. But last night I got and engine light came on and read the code to be this.(both banks were reading same fault) Has anyone had a code thrown up due to manifolds? http://i1102.photobucket.com/albums/...psbdqb7pgg.png I cleared the codes and next day went for a long 25mile drive, no light came on but I read the codes when I got home and it was showing the same fault again on both banks. Does this mean I have to map it out?
My AP manifolds threw the P0430 once about a month after I installed the headers. Cleared it with my code reader and it hasn't come back in about 4 months.
I was hoping it wouldn't come back but after a drive it stored the codes without a light on. Did you plug the car back in to see any codes again?
This is the second report I've received of this in the last month, which is quite odd. On the Vivid Racing side, I show we've sold 20 sets of these headers this year. That doesn't include all the sets Agency Power has sold direct to clients or via their other distribution channels. The majority don't get a CEL. Some get a CEL, and then once cleared, it doesn't come back. And I've now had 2 reports in the last month of the CEL continuing to come back. Best solution would be to purchase the Fabspeed O2 sensor spacers first. That is the least expensive option and they make a specific 2 piece version for the F430 due to clearance issues. If that doesn't get it resolved, then tuning or O2 simulators would be needed. Shoot me an email at [email protected] with your name and I'll pull up your address and get you a quote for the Fabspeed O2 spacers. Should be under $180 including shipping. -James
Thanks for the infor James, with the o2 spacers are they positioned in the manifold part or the next set of sensors?
Yours is a Euro so they would go underneath the front lambda sensors. As an aside, I've fitted quite a few sets of AP's now without issue. Did the adaptive values get reset when they were fitted?
Reset adaptive values? I didn't reset anything. We just replaced the manifolds and off we went, How do I reset them? Is this the problem that I didn't reset
Installed new AP headers to my all stock exhaust last week, got a CEL after about 25 miles and three cycles. Cleared the codes and after another 25 miles another CEL. I might try clearing again but I think the problem will repeat. I guess 02 sensors should be my next step. Has this worked for anyone?
Your o2 sensors are working almost too well if they can sense the lack of 'clean' air. Did you disconnect the battery for ~30 min and go through the reset procedure for the car to relearn parameters?
Besides the codes being thrown, can you say how the sound differs over stock? Is it much louder? I want to do the headrs, but I don't want the car too loud...
It is very, very loud. Love the sound tho. Still haven't had any code issues other than he one time referenced above.
For sure do the valve controler.Check with Steve Bisel ar Forza Componenti. It is hard to describe loudness but for me headers and stock exhaust and valve closed is about the same as all stock exhaust with valves open. I have a coupe and the sound level inside with windows open is not bad and you can have a normal conversation, it is the people next to you and behind you that are getting blown away. Sorry...(not really)
I was told the later cars have more sensitive sensors/parameters, hence the light keeps coming on. I will get it mapped out when I get a chance. But for now I'll keep an eye out on the codes. As for the sound it is louder when the valves open, and before the valves open ie idle normal driving it's just a little louder. The sound is the same as stock though. I'm glad I done the manifolds and love the sound it's amazing
This is why I would never put aftermarket headers on a 430. I would on cars with no pre-cats. I've read too many stories like this where frustrated owners are chasing dreaded CEL issues. If your car is registered in a jurisdiction with emissions testing it can be a serious hassle to have CEL because clearing the codes will cause the car's monitors to not be "ready" and you will fail just for that even with light off. Getting a 430 emissions test ready can be stressful and a hassle. Many posts on it. These damn pre-cats are a pain but I guess Ferrari had no choice in order to meet ridiculous emissions rules which IMHO should not apply to low production cars. Sent from my iPhone using Tapatalk
I wouldn't call it a "dreaded" CEL issue or a chase. $150 gets you the Fabspeed O2 sensor spacers which work most of the time. From there, Capristo offers MIL eliminators. They're spendy, but they allow you to pass scanned emissions tests, and if those aren't a concern, then a tune turns the CEL off and gains some power throughout the powerband. -James
So that is all the factory could have done in the first place to avoid the pre-cats? The failed MK1 headers have cost the factory a lot of money in replacements, etc. Then why do MK2 headers have pre-cats too if the factory could have just done something like the above?

I installed AP (ceramic coated) headers along with FabSpeed 02 spacers on my 07 F430. The 02 spacers go on the secondary cats (right under the exhaust silencer) . No CEL at all. Sent from my iPhone using Tapatalk
Let me get this straight because I have a 07 430 and installed a AP header with stock cat and I just got cel light P0420 p0430 which is o2 problems. Do you install the Fabspeed 02 extender on the sensor that was moved from stock header to new header or the 02 sensor after the cat? Fabspeed site says after cats (downstream).
The Fabspeed site is correct. They go downstream of the cats. I have Fabspeed headers and cats, and was getting the P0420 and P0430 codes, which came right back after being cleared. Installed the extenders, cleared the codes, and about 1,000 miles later they haven't returned.
This should help, make sure the extender is pointing towards the engine Sent from my iPhone using Tapatalk
