your best bet would be to try the one from mat at dmgrs . all others i have tried were useless and did not last 2 yrs. other members on here have i believe bought from mat these backboxs but i could not say for sure if they are more quiet than the aftermarket garbage and certainly not the originals. hope someone on here can advise you further. i put a stainless system on mine and its still a bit loud but it should outlive the car. mats version does look the part though.
