Ferrari F430 Manifolds

[ck888]

Good Day,
Im looking to replace my manifolds on the F430, i see Top Speed headers are sold out and prices seem to have increased over the last few months. Has anyone any info on any suppliers at the bottom end of the price range ?

My car is currently waiting for its new headers to arrive from Italy - I suspect they are unfortunately not at the bottom end of the price range though, but german tüv and warranty kinda limited by options ...
Good luck finding some - maybe somebody like Tubi or capristo?

[MDL111]

One more thing - can’t you get them refurbished? I remember on my 355 I had refurbished manifolds (at the time from Verdi - without wanting to open that can of worms again...)

[ck888]

Ok thanks for that, i will make some enquiries. The current headers have not failed but im looking to swap for peace of mind in case they do fail.

Hi guys , i know these cars extremely well.

I want you to know that you can fit the 430 challenge car manifolds to a road car, they are less than half the price! you can buy these direct from main dealer.

Sam I am purely curious but why would the Challenge headers be cheaper? You'd think the opposite would be true

The Challenge exhaust manifolds don’t have the pre-cats that are incorporated within the road car manifolds, hence the cost differential.

Thanks interesting - Makes me feel better as then they wouldn’t have been an option for me anyway

Thanks. You’d think they’d still charge more for the part for some reason or other. I’d happily fit that we’re into own one. Why do I hear about the manifolds being so bad? Are they under spec or what? Just curious I’m not an owner.

There are two issues, the pre-cats fail and can get ingested into the combustion chamber. Pre-internet this fault probably wouldn’t have been anything like as well publicised as it is now ...

But secondly the manifolds have a propensity to crack. It’s the latter issue that Ferrari attempted to address with a modified design (initially they were substituted under their warranty scheme) .
Some will say the modified manifolds have solved the issue, plenty say they haven’t ...

The likes of Capristo, Supersprint, Agency Power (and dare I say Fabspeed) amongst others, have come up with improved manifolds, both from a durability and efficiency perspective.
Capristo have also designed an alternative exhaust mounting system which allegedly reduces stress on the manifolds, and thus all but ensures their manifolds will not crack/fail.

The Yanks seem more willing to try Taiwanese and Chinese manifolds, they’re considerably cheaper than the brands I’ve listed, and whilst the manufacturing quality frequently isn’t as good, they do seem to do the job.

If you really want to get into the nitty gritty, there’s plenty of subject matter on FChat, and a search on here will find a couple of excellent t threads on the matter too.
All are perfect for the long, dark, cold, wet Winter nights ahead

I don't own a Ferrari, not have any specific Ferrari knowledge, just reading out of interest as I like all things automotive.

Curious to how cat failure ends up in the combustion chamber? Is it a gravity issue due to their location and bits falling into the open exhaust valves? The exhaust gas flow would be away from the engine otherwise. Thanks.

It's suggested that during the valve overlap period (and specifically whilst the throttle is shut on the overrun) there can be sufficient negative pressure within the exhaust ports to draw any loose cat substrate into the combustion chamber.

I can vouch for Top Speed; very good for the price. I currently have Capristo and the quality of fabrication of the manifolds is very similar.

I prefer the power deliver of the 4-1 manifolds like Capristo, Supersprint, or AP. The Capristo 4-2-1 are punchy in the midrange but comparatively flat at the top end, and they are also quieter.

Interesting.......... that is certainly an option, thanks

I have read conflicting accounts of engine bay temperatures of wrapped manifolds versus unwrapped, would it be an issue to install unwrapped manifolds ?

If you’re planning on running the Challenge manifolds (and thus in the process deleting the pre-cats) the engine bay temperatures should be reduced anyway.

For sustained, heavy track use, the heat blankets supplied by Capristo are probably a good idea :

but for road use in our average UK temps, I’m not convinced of their benefits.

[ck888]

Yes i would agree with that, its something to be aware of the first few hard drives i guess
