so someone took a regular CAI, cut it in half and gave you a rubber connector to put it back together and called it something new. wow.

It's not a dual pipe like most would think... it's 2 pipes that you put together to make one pipe.

Why? Well you could have a CAI when you want it or a short ram when you want that. Other than that I see no benefit other than it might be easier to ship.

I've seen those for like 1.5 years now. Not really... "new"... but more rare than normal ones.
