all this swapping has got me confused! first, you bought a full standard hindle. then bought a brock alien head can only, right? did you sell the hindle can only and kept the hindle headers for the alien head can?
my head's spinning right now and i haven't even had a drink yet. maybe i need one...
The header that works with a Brock's pipe is the Hindle Race. The 2.25" core.
The Hindle Standard has a 2" core and is not compatible.
I did buy a standard Hindle system too, and have since sold it. Wanna see a pic of the standard???
It's the same design as the race, but the race goes from 2" to 2.25" just after the flanges. You can see where in the pics. The standard stays 2".
Why do you think there is no equalization pipes between 3&4. Stock has it for all model years.
I'll let Brock answer that.

"Subject: Why Brock’s Performance (by Hindle) Exhaust Systems are Different.
Most of the differences involve thought process, design and test criteria...it is a philosophy.
Basically, we find that other exhaust companies concentrate on development using road race technology. Low end and mid range power (at partial throttle openings) are paramount to assist cornering speeds, etc… In this type of racing, the machines only maintain high rpm usage for a limited time before decelerating to power up again. A sport bike drag racer needs lower revs for a moment on the launch before wide open sustained high rpm usage is required.
We are drag racers who not only street ride our machines most of the time, but also want the maximum performance out of them at the track...bragging rights are on the line every time we stage!
Mid to high rpm power and a dedicated power curve to provide the best possible ACCELERATION is our goal. If a late model 1000+ CC sport bike needs more low-end grunt, we can’t tell from the way we use them! (Hell, we can’t keep the front ends on the ground!!) So, why are most manufacturers concentrating on small primaries, crossover tubes, etc…? These are road race ‘buzz’ words that sport bike drag racers don’t need. A surprising aspect of this difference in goals is that we really don’t lose anything in the areas they target...and we run off from them up top!"
All that I can tell you is that I am extremely happy with the power I am getting out of the big ninja with my Hindle Race header and Brock's alienhead. Atleast now that the autotune is building me a map.
