    Does anyone know whether an F355 with Tubi exhaust would exceed the noise limits at Castle Coombe - I gather they are very strict ?

    Sadly I would think no chance. test is 1/2 metre from exhaust at 3/4 revs, limit is 100dB unless it's one of the few test days where I believe the limit is 105dB, altohugh not sure that would help JRS's 355 with tubi and no cats was over 110db. my standard 355 with cats is around 99dB at 3/4 revs and I think I'm right in saying that for each dB over 101 then noise is roughly double!!
