Has anyone experienced low ball bids from dealers when selling an F430 with aftermarket headers like Agency Power, Capristo, etc.?

I know they look for any excuse to make an insulting offer but wondered if they pick on this too.
No experience of low ball bids but always keep the originals, many cars I've looked at in the past have had aftermarket exhausts but always had the originals as well. (if the OEM headers are knackered then this is obviously a problem). The issue for an Official dealer will be warranty, they won't/can't put warranty onto a car with aftermarket headers.

Yes, keep the originals and have the broken pipes repaired, some do with CAT some remove it when repairing the 4 into 2 weak points, look at my other posts and youtube videos, 99% of the time the stock manifolds break at the same point, it's never a CAT issue IMHO, simply remove the metal clam, repair and keep to one side or put straight back on, with the metal clam removed you can check them as much as you want, a huge plus point if you want to stay with stock parts, obviously you would need to use heat wraps but they only cost pennies.

Look at them, both broken at the same point

I personally would much prefer originals than non, I always think that original shows an unmolested car and if that's the case the owner will have been more likely to treated the car better, strange how the 430 suffers this problem whilst other models don't, Mike

In this instance I'm afraid I can't agree - It is unfortunate but OEM F430 manifolds are simply a time bomb and aftermarket is the only way to go long term unless you want to keep up the annual warranty and rely on them stumping up for an engine rebuild if/when the pre-cats gets sucked back into the engine. It is well known that the header quality and the thermal stress in the F430 exhaust system causes major issues.

I agree with the manifold element totally I was more thinking after market exhausts really, Mike

I'm currently looking to buy a Ferrari V8 and there are some 430s which are within range price wise. Question: if the car has an aftermarket exhaust, will this mean that the dreaded OEM manifolds would have to have been changed too, or could they be left in place? I've seen a few cars for sale where the exhaust has been changed, and wonder if that's one potential problem area which has been addressed.

It depends on which part of the exhaust has been changed. Generally, there are three sections:

1) Manifolds (x2 - 1 for each side)
2) Catalytic Converters (x2)
3) Silencer (x1) and tips (x2)

You will need to ask specifically if the manifolds have been changed.

Thank you Voicey. I can see from the photos that the silencer section is non-original. I was hoping that maybe that section would only be compatible with a non-Ferrari manifold. I'm in Europe, so dealing with French, German or Italian speaking sellers. Not always easy!

Ask for a photo of the manifolds from the top of the engine bay - if they are uncovered or covered in blankets then they are aftermarket. Otherwise they'll be covered in tin = OEM.

I have a brand new set of capristo manifolds that Im not going to be fitting if anyones interested. Also I will be taking off a set of used OEM mk2 manifolds with under 3k miles on them.
I would be very interested in the capristo manifolds if you still have them please drop me an email

Excuse my ignorance, but how does the manifold cracking jeopardise the engine?

If a cracked manifold is left on the engine then there is a danger that it will damage the small catalytic converter that is inserted in the manifold itself (called the pre-cat). If the pre-cat breaks up then there is a danger that small bits are sucked into back a cylinder during the valve overlap.

Additionally (and applicable to many other cars), a cracked manifold can let air into the exhaust system. This will fool the Lambda into thinking the engine is running lean and tells the Motronic to add more fuel. Running rich can wash the oil off the bores and lead to cylinder liner damage. Fuel can even get past the rings and into the sump which dilutes the oil (very common on diesel engines with leaky injectors).

hi GT2 thread resurrection! can you link me with your guy who fabricated the manifolds?
Im thinking of tackling mine. Albeit Ive got a cracked rear silencer so am likely going to put on a sports exhaust back box.

Because I have a guy who builds great systems. Capristo do not have an exclusive on these skills!

He will get my capristos to have a look at and he will build me something and then I will sell the capristos. He's also building me an exhaust which will sound something like this just not as loud!
