300ex cobra jet exhaust
sounds like a sick harley,
I got it with the exhaust already on, and the carb jetted for it,
It feels more powerfull than my friends 2001 300 with stock header (WB E series muffler) and stock jetting.
Before I went up a tooth on the front sprocket, id annihilate him in a drag, i also weigh about 50 more lbs than him,
after i went up a tooth, im still quicker, but not by much, and i top out a little higher than him
( i also have a real wobbly badly bent rear rim)

i have the same exhaust for the 300, as long as you dont have the jet model, you can put a "quiet core in" you can get one from dennis kirk for 25 bucks
i bought mine immediatly after i installed my cobra exhaust, much quieter, core fits tight but works fine
cobra core for quietness!

i am still also jetting my carb, i have tried many combinations and it still pops a little bit on decel from high rpms
i have been using keihin jets
my first set up was 128 main and 40 pilot and the needle on 4th slot with the air lid on
i also tried putting in a 42 pilot and still get a little pop
my next set up im gonna try the air lid off 132 main and a 42 pilot
it seemed to be running perfect other than this little pop
