Do yourself a favor and save up some money and buy yourself and nice full sytem exhuast with a jet package. That will help your k&n to do what its gotta do and it will give you a nice amount of low to midrange. Depending on what type of pipe you get. I'm not too familiar with blaster pipes but you can always make a post and see what everyone has to say.

 

Sorry for posting the boost bottle, I didn't know they sucked since I don't have a shee or a blaster. Just thought it was something good because a friend of mine has one, and it has power for a little 250.
