I was thinking about converting my P1SC into a D1SC by sending it in to get converted, but I recently found a P1SC-1 head unit for sale and might pull the trigger based on the price. From my knowledge, the only differences between the D1SC and the P1SC-1 are that the D1SC has a bigger exducer diameter, and it is capable of 200 cfm more than the P1SC-1. Is it worth spending the extra money on a conversion? Or should I buy this P1SC-1 that is in great shape for around $700? Lemme know what you guys think
