Their, may be, their, they're Jeezuz

And at the end of the day you might make 5hp more and that just doesn't give me a stiffy.

the problem with exhaust systems is they are the product of compromises, (straighter more open for hp, more tucked in for ground clearance,silencing for more acceptable noise level, finnish/shape for looks etc).
now depending on your priorities some of these features will be higher on the list than others so to insinuate that someone has fallen short because they did'nt choose the highest hp exhaust is wrong. heck mike even you gave away hp with your change from d&d 2-1 to the 2-2 just because they look and sound better, as they say "you pay your money you make your choice".

as a side note for sascha
bob farnham a leading engine tuner in the uk who's engines have won many championships in the uk from 2 strokes to classics to the latest r1 gsxr cbr and is probably the number one hinkley twin engine tuner in the uk has a very trick thrux as his personal bike and he uses the bc high pipe and mini cone system even though he could have any system he wanted, he knows he's giving up a handful of hp but accepts that for the look he wants.

update
i fitted an innovate mtx-l a/f ratio gauge a few weeks ago to help me adjust the fuel maps to better suit the new set-up of the bike,
but unfortunately due to the british weather i was side-tracked onto another project building a large wooden boat capable of carrying two of every beast.
but i did manage to get a couple of dry days to let me get out on the bike and adjust the fuel mapping that should be close enough to let me get it on a dyno,
so hopefully i will have some dyno charts in the next couple of weeks.

mike-tt special

Well guys..the dyno runs are done, and we even have a youtube video..

So bare in mind, this is with a 790 inlet & 865 inlet cam repositioned in the exhaust side, standard throttle bodies and the ignition advance, and fueling still to be tweeked..

Papa Weeley

Well done! That oughta be enough difference in "kick" to feel in the saddle!

thanks papa weeley
if you pause the video at 5:27 and look at the torque curve you'll see how strong the power delivery feels, it makes 50 lb/ft at 2500rpm rising to 60 lb/ft+ at 4000rpm then holding that to 7500rpm (basically it pulls just as hard whatever the rpm).
i think there is alot more to come when i fit the daytona 42mm throttle bodies
