Thanks for asking the question...
I am also trying to understand why would the header make such a difference.
And in a way, I am glad that the race header will not work with my "regular" SS2R...Puts it out of my "wish I had it" list, at least for now. |

My guess is because the header tubes are longer before going into the collector. Probably all about exhaust pulse timing, keeping them separated longer, and bringing them together at a better timing in the pulses. Something the engineers couldn't do with the stock header, because of the length the stock muffler used under the bike. |

Loren,
Mostly right in your statement.
The stock header was a compromise. The originals from 95 - 96 were 2" collectors, the later models were 2 1/2".
The header runners were made as long as possible for broad performance. The muffler had to be able to pass EPA sound regs.
A race header with the longer head pipes that wrap around the front and lower left of the motor are too long to allow a regulation meeting muffler. Performance is better but sound is out of spec.
BTW Kalali, a SS2R can be made to work with a race header. I've done it on my S2 and will probably do the same on my M2 when it gets back together (soon!).
I don't have any pics of the SS2R mods but I may have time to pull the cover off this weekend and snap a few.
The short version is: shorten the main can about 4 inches, cut off the front curve, expand the front pipe to slip over the 2 1/2" collector on the race header.
Shorten up in interior core and weld back together. Restuff and reassemble.
Still not too loud and works very well.

Brad, thanks for the explanation.
You know, I did a bit of a soul searching last night and realized that I still have a long way to go to fully exploit the power that my bike has to offer as it is right now...given that I've only had the bike for a year.
While I know there is no such a thing as too much power, this thing is already pretty scary fast for me... |

kalai, the first time you get ate up by another bke you will be on the mission to find more power! im looking into 88 kits at the moment. and trying to get ahold of a local buell tune shop to get my injection system up to task |

I know what you mean Ron but I am willing to bet there is always someone out there who will kick my ass no matter what I have...If nothing else, their nuts are bigger than mine when it comes to squeezing the juice out of the bike.
Unfortunately my nuts stopped growing many years ago...(at least that's what my wife tells me).
To each his own. |
