Your current setup is an SLP catback commonly referred to as "2OTL" (Two on the left), this catback was offered on early 4th gen SS models as well as being available via SLP's aftermarket retail program.
It consists of a single inlet, dual outlet (same side) muffler.
If you want to make a FM 10-series muffler work with this system, you can weld it in place of the current muffler and use the existing intermediate pipe for the inlet, but you'll only be able to run one tail pipe for the outlet (unless Flowmaster is now making 10-series mufflers with dual outlets, but I don't think they are).
If you want two mufflers and two tail pipes, you'd be looking at some sort of true dual system, in which case you'd have to replace the whole system since the current setup is designed and routed for a single I-pipe, single muffler inlet.

IMO, if you do remove the 2OTL muffler cut the inlet and outlet pipe about 1.5"-2" out from the muffler body. You'll also need a length of 3" diameter straight pipe since the muffler body is noticeably shorter than the 2OTL muffler is.
Part number for the FM10 muffler is #8430152 , I'd also consider the FM Super 44
#9430452.
