Stm Cat back exhaust & test pipe

[Brandonjffrs96]

Does anyone happen to have a stm exhaust and/or test pipe for sale? I recently picked up a down pipe which I thought was stm but it turned out to be strictly. Great quality from the looks of it and in fact it looks a lot like the stm down pipe. Anyways will this be compatible with the stm exhaust and test pipe? Also what do y’all reckon the strictly down pipe to be worth? I heard they no longer make these.
