    Default 430 Manifolds

    Has anyone got any experience of the Superformance manifolds (stainless steel ) ?
    I need to replace the right hand side on mine.
    Do they swap straight in , and are replacement cats required ?
    Can the old cats be retained ?

    Thanks All
    Spider,or coupe? Just get one of each.

    Manifold replacement for the 430 is well established now as a must do if you are driving the car as design Or it is subject to many short heat cycles. They are a certain to fail weakness in Mk1 guise and many were changed under good will contributions to Mk2 guise. The trouble is the root cause problem was still not addressed which was the poor design of the whole system and chiefly its ham-fisted bracket design. So even if you replace the manifolds (headers in the US) you really should at least replace the systems brackets which snap repeatedly anyway. More realistically a new aftermarket system including headers is the way most owners go. It is a DIY job but not easy and takes a lot of hours if you are paying for it as the manifold bolts are not that simple to access. Still needs must.

    The only downside to this is unless you are using mk2 headers you automatically lose the primary cats which are embedded and the car will likely throw CEL's until you get a re-map. Everyone I know who has done it had this issue but I know some folk on line seem to not had the problem. I would budget for it so there are no surprises. Equally the standard headers are heavily heat shielded (they sit right next to your fuel tanks) so I had mine ceramic coated inside and out. Engine mounts are relatively cheap to replace at the same time too.

    Some folk find the new headers too noisy when making the swap so worth auditioning some cars local to you perhaps to get the system right for you. If you replace with stock IMO I are just throwing money away as they WILL fail.

    Thanks Mod

    The car had a replacement set early in life (with another set of pre upgrade manifolds prior to my ownership.)
    I then had updated ones at circa 15k miles. Good will and warranty.
    These have lasted for 30k miles.Car now on 45k miles.
    So I guess they have done well then.

    I replaced my manifolds and have no CEL lights in 5 years in spite of loosing the small cat in the factory manifold.

    I used Capristo manifolds as some of the alternatives arent flat across the manifold face, (meaning using two gaskets or having to get the mating face re machined to ensure they are flat) or have issues with bolt hole alignment (either not fitting onto the studs in the head , or have the header primary pipes welded so close to the bolt hole, putting the nut very close to the primary pipe and making it difficult or impossible to bet a socket onto the nut.

    The heat is another big concern as the manifold is close to the fuel tank. The Capristo manifolds have heat blankets which are very very effective. You could run the car for hours and the outside of the heat blanket is only warm. I noticed a much cooler engine bay once fitted.

    I've bought a pair of unused TopSpeed headers from a guy on a Facebook forum. They've been ceramic coated by Camcoat. Total cost new plus the coating was circa 1,500 which is at the bottom end of the market however, feed back on forums, you tube etc has been good. They will go on (by a specialist), as soon as my warranty expires in December.

    Default TopSpeed headers

    I changed mine a few months back and am very happy. The nice is great on top of the Ferrari Sports exhaust and although I am getting the CEL - AV Engineering (aka Voicey) is going to add his mini cats and not too expensive so hopefully will sort out the nasty CEL.

    Definitely agree with previous comments about ceramic coating as a must or wrap them ins one sort of heat shielding tape.

    There are videos online from Dan Hu Supercar Guy on U Tube.
