    ultra 250x headers

    well dan's on his sweet way home with a huge smile on his face.mocked up half of the exhaust today. tested it. his boat is bone stock. it ran 7780 before now it's at 7940. and thats not the whole kit. sounded wicked. exceleration was extremely responsive. very impressed . so now i have to finish making the headers and send them to be prototyped. i think when it's all said and done you should see atleast 300 rpm's on just headers alone. gonna post audio of it soon.

    Will this be a straight through exhaust without a waterbox? Any idea on the weight savings between the headers and the cast iron manifolds?
