Anyone know where I might get one of these(for 07 Attak) for under $300, they used to sell these for under 200, two years ago! 
Might get more response over on the four stroke side.
Port Yamaha has a sticky in their forum on the 4stroke side about rear exchanger kits. Not sure if it's apex or vector but there is #'s and pricing in it.
Still over $300 after shipping...
Okey dokey then. 
Have you tried 'Laneo'? He may have a used one kicking around.
