I think the flowmaster hush power would work perfect, as for Borla I'm not sure. Really any exhaust will probably work I would just make sure it fits between the 2 crossmember ( it allows a bigger space), I think I measured btween the to coss members and it was 17 inches so any muffler in that range should work... I would also look at the pipe inlets I would make sure they are on one side and not cati-cornered... But I prefer the round it's easy it fits perfect and has a great growl!! Good luck glad this helped!! I'm always on budget build mode!!
