    Complete Headers For Seadoo 4 Tec

    I am finally ready to spill the beans. I have wanted to say this for a long long time but couldnt.
    As you all know i have a huge drive and passion for ski's and performance. To this day no one execpt for "BO Dupriest" has built a set of headers for our ski's.

    WELL I HAVE.
    My company name is Black magic headers I.N.C. I will offer a few versions of headers.
    1. VOODOO series. closed corse racers
    2. Black magic series mid to top end "drag"



    The VOODOO series are equal length 100 % full high grade stainless. and most of all USA made.

    These are 100% water jacketed. Not spray injected.

    The black magic series will be 100% water jacketed for turbo's.
    I can not reveal much more info yet [ ex price, availability] , but that will come soon.


    Yes i have rigorously tested these and know what they gain. That much i will tell.
    On a completely bone stock i mean bone stock 07 rxt. I picked up 200 rpm's and and almost 2 mph. "1.8" yes they were back to back tests.
    Same day with headers same day with stock exhaust. These headers will wake up big time I mean big time with bigger injecters super charger ext ext.

    So bottom line just putting a feeler out who would be interested.
    I am a hardworking family man that is just trying to make a "HONEST" living.Not trying to get rich quick . I will stand 100 % behind my product.

    Please give your opinion on how you feel about this. If you want to here them here is a few links.

    very truly your's

    nice work Jason. I've seen his work first hand, i've seen his drive and motivation and work ethic. He's a great guy.

    His gains, IMO, are conservative. not only was the ski bone stock (even with a stock air box)... it was kinda rigged together for a test run with the water routing to keep things very very cool, and too cool sometimes hurts power.... he also MAY have been against the rev limiter (he was over 8200 i believe with the headers), so the gains are at minimum what he's posted. there was no tweeking or sweet fine touches, just a bone stock swap with nothing but 12 bolts changed to swap exhaust manifold for headers.

    i would imagine more mods and more boost and more exhaust scavenging would yield even better results?

    ahhhhhhh, i can't sleep at night all i think about is my turbo setup he's gonna have for me with headers

    nice work
