With the heat on, do you smell coolant (sweet smell)?
Does your windshield fog up or get a thin moist film on it just above the vent?
Is the carpet at the footwells damp/wet?
Is there a chance its leaking onto something hot enough to evaporate it? Its doubtful as the M50 exhaust is nowhere near coolant hoses and it sounds like you're losing quite a bit.
Its not rocket science, coolant doesn't travel any further back than the heater core, so if you don't find signs of an external leak, you might want to start thinking (and I hope you don't have to) about that coolant heading out your tailpipe or into the oil. Check your plugs for crusty white deposits, check the oil for frothy, milkshake like appearance (on the dipstick, under the oil filler cap or under the valve cover). This could indicate a failed head gasket/cylinder head. For now, just let us know how much you're losing and what other things you've seen.
