Do you have a link that shows the system? My car was one of I believe two used to develop the cat back exhuast for Borla. I am curious if Borla/Mopar removed the crossover in their production system.
I had the crossover put back on my car due to exhaust volume (db). I do have the Borla mufflers which sound great at all RPM levels, but not sure if they are more efficient then stock.
