This carpet is no where near the quality of the original carpet. I guess the mass backed would be closer but I ordered the carpet without the mass backing and am really no satisfied at all. You have to cut out you existing heater vents from your old carpet and use them in your new carpet which does not hold them in place. You have to basically be the upholstery shop and make sure you cut out all the holes in the right locations, its a time consuming task.
Terrible time.
