what should i get?

Depends on your engine modifications (if any). Please list any modifications to your blaster, it will be a lot easier to determine the best pipe for your setup that way.
 
Anything but DG brand will be a power increase. From there it depends on how much you want to spend. Trinity and Toomey pipes are very good, but they cost a little under $400. FMF pipes are not as powerful, but are great for trail riding. You can always find used one's around.
 
If you want power in the low/mid range a DMC Alien works well, if you want it in the top of the range go for a right bend pipe.
