no they dont make an hx40 5 inch they run 4" the reason you can run a 5 on twins is because with the lower turbo it sits lower than stock so you can fit a 5" down there it barely fits between an nv4500 and the frame rails

the outlet on the big turbo for twins is already 5 inch. all it is is a flare peice of 5 inch pipe thats clamps to the turbo. you can have a 5 downpipe with your turbo. thats why all 5inch systems have a 4inch dp and then goes into 5 inch
