    If Jetex does a 2.5" non res ( cancels out middle box ) it will be perfect as their back box packing material cancels out the coo .

    Will be deeper , but because the back box doesn't have packing material no absorbtion of the vnt coo noise .

    I was thinking of that to be honest, delete middle and get a smaller backbox something like a powerflow twin tip
