Guys to clarify, I've been 'offered' these to buy, I have first offer to buy them if me and seller can agree a price. I have no idea what to offer, obviously want to get them as cheap as I can but also the guy knows what he has but is keen to sell and get some cash. I too prefer the look and sound of a cast manifold over headers, less hassle too. Other than looks I guess I'm not getting much for my money, I have some stock ones anyway.
