ULTIMATE sucks ***......gave me one in exchange for 1150 dollars and dripped from the second it was installed, 2 pinholes in the welds for the input hub and after contacting Lenny and him insisting it couldn't be the converter we R/R it multiple times after changing everything but the converter and then I decided to air check it, something he never obviously did, and found the pin holes and also a cracked input hub. He told me it was a vendor issue as he didn't think it was a 2 piece hub and he fixed it AFTER CHARGING ME AGAIN!!!!!
