It will be very loud running with just a mid-box on a petrol 306.
It works on TD's / HDi's as the turbo sort of acts as a silencer, but you don't have that and since the mid-box is stright through, it's going to be distinctly noisy. Remove your backbox, start the engine and give it a bootful of revs if you want to see what it'll sound like... and then re-fit the backbox when you realise that you couldn't tolerate that everyday (nor your neighbours!)
