from the pics I've seen of the DMC, it appears to not have the same bent up stinger end at the connection as say the stock FMF, PC, Toomey ect. pipes.
it looks to have a more straight connection between the silencer and pipe ?
maybe someone with a DMC can chime in and confirm if it appears to work with other front pipes.
they are all not the same, at least the Dyno-Ports, FMF-SST's and older LRD's use a straight thru design and those silencers will not work with other pipes and vice-versa
