I just purchased the HiFlow exhaust for my '02 SEV6 and found that the fittings aren't same as the factory.

On the stock system, the shorter pipe from the Y to the front of the muffler has a heafty connection point that isn't on the Calmini system?

I would be ok with adding this to my truck if: this wasn't such a heafty connection (only connection between the manifold and muffler); this upgrade voids my warrenty and the lack of this connection would causes a greater risk of me damaging my system; and I could easily have the connector added by a local muffler shop.

Courtesy Nissan is being great about finding out why this system says it is for the '02's but is missing a very key connector.
