I'm currently in the process of taking out my interior so I can replace the carpet, add a rear seat delete, paint the rest of the interior black and install my summit racing seats. I have 2 options right now with the carpet. I can get the massback for $190 or get the regular carpet for $115 and use sound deadening while its all apart. I'm not sure which route to go. Is the mass back really worth the extra $75 or should I just use that money towards some sound deadening? I don't plan on going crazy with the sound deadening because I don't want add a lot of weight or spend a fortune on it. thanks
