I have two sets of EMI Thunder Manifolds for BBC. Excellent shape , freshwater use and only 109 hours on them. They include polished risers , rubber couplers and Corsa ASR marine exhaust tips. Text Ben at 218-969-5864 for pics or info. Will sell single set or as a pair for twin. Asking $1600 per set or $3000 for all but am open to offers and I can ship.

do you know if these will fit a 496 mag ho. I have asked this question in another thread but have no gotten an answer. Just curious, why are you selling. I’m looking for a performance upgrade. Do you know the gains I should expect by these and are they for silent choice set up
thanks
Seth
