    Exhaust manifold choice

    I'm rebuilding an F7R atm and have choice between 3 manifold, the 16v, williams or megane f7r.

    I have found some posts saying the 16v manifold is a better performer overall, anyone know more on this subject?

    Cheers,

    Arthur

    From anything worth believing that Ive read over the years,
    any modification's to air intake/exhaust from standard will all depend on a remap to show the results.

    Williams manifolds are only fit for throwing in the bin, F7P manifolds are optimised for torque but the megane is the best of the 3

    I'd swear there are no cracks in my mani.

    You 100% sure Paddy? If so i'll fit the megane manifold....

    More people with experience?

    it's a one time decision as i'll be retro fitting the exhaust to it

    The only disadvantage I can think of with the megane manifold is having to do modifications to make it fit the clio exhaust properly

    It will end up on a renault 9 anyway so exhaust is no problem. Guess i'll take your advice and try the megane manifold
