Exhaust Crossover pipe

My Techart exhaust made by Supersprint has two separate exhaust chambers/cans which do not interconnect, whereas most other after market systems do in some manner. Is it worthwhile getting a crossover pipe welded in, what difference does mixing the exhaust gases between the chambers make PLEASE ?

The reason most automotive engines that have a flat opposed or a "V" configuration have an exhaust system that ties both banks together is to equalize the back pressure on both banks or cylinder heads. This will better control the airflow through the engine as a whole, since the air intake comes from a single manifold. If the back pressure was not equal, one bank would get more air flow than the other. This will cause that bank to run leaner or the other bank could run richer as the computer tries to make up for one or the other condition.
