Other B pipe with only 2 screws??

[danimal365]

I just got a blaster limited pipe, the head pipe doesn't look like my superjet head pipe. There isn't a screw in the bottom and I'm only seeing 2 adjustments. I looked on FP's website and it makes no mention of a pipe with only 2 adjustment screws... wtf? Also what's up with the screw on the inside of the pipe?

old head pipe had only 2 screw i think

 

[danimal365]

There is a "regular" screw in the hole inside the headpipe that is just before the chamber. Its in a similar spot to the 3 adjustable screw that is missing. I've got my superjet setup with that being the only open screw, so i guess it could be ok...

I don't know if any Yamaha B pipes had only 2 screws, but if you notice, that pipe doesn't have a "B" on it. So I believe that is an older Kawi headpipe.

true and the water outlet at the bottom of the head pipe is really not the same as SJ b pipe

I took the "blaster" headpipe off the manifold and put my SJ headpipe on it and i can't see the difference in angles... I'm gonna be pissed if this doesn't work...

That's the A headpipe, just 2 adjustable screws and a fixed 3rd hole in the bottom that you could plug with a screw to adjust for more bottom end. I don't remember there being much else different.

I ran a Mariner Factory Pipe on my SXi with stainless chamber for a few years.

That A pipe should be 10mm taller at the manifold flange on the headpipe.

Yup it's 10mm taller.... What does this mean for me though... will it still work in the blaster... did I get screwed?

 

[Cannibal]

Nope, should work fine. In fact, some argue that the extra length of the headpipe adds just a little extra volume that could result in a bit more oomph....I say the gain, if any, would be negligible.

I would say though, these headpipes don't carry the same value as a B pipe, so if it wasn't advertised as such, you may be entitled to a little bit of compensation ($50?), if you can work that out with the seller....

I had a B pipe and a Mariner pipe. I sold the B pipe and am happily rocking the Mariner pipe. Ride it, love it... If someone says your pipe isn't genuine then grind off the Mariner writing and etch "My F-ing Pipe B-tch" instead and it will instantly be worth more than some printed "Factory B Pipe" writing...

Make sure you don't call it a "b-pipe" when talking to Cindy at FP...she will quickly correct you and say "there's no such thing as a b-pipe, there's a b-head pipe!" :smashfreakB:

 

[danimal365]

So to set this "A" pipe up I should start with the screw pluging the bottom hole? I'm putting it in a blaster with stock everthing else and not super concerned about losing some top end

 

[Bern]

so are these worth more or less than i B pipe head pipe?
