I have a couple of friends who have blasters and one of them was thinking about getting the Pro Curcuit set up and the other one has FMF which is better Thanks for your time

 

the FMF is better. there is one for sale on ebay

 

Recently added a Pro Circuit pipe/spark arrestor silencer to 2000 Blaster (along with K & N filter). Nice improvement in performance and sounds great. Based on fairly extensive research I chose Pro Circuit over FMF. Both are excellent, so you really can't go wrong either way. I would also recommend that you add a Boyesen Rad Valve, AMP Link, and Vito PowerPiston. You can do all of the above for about $600. You will be amazed at the change in your Blaster. Rear brakes are the next step, and really all you need to do. Any more and you might as well sell the Blaster and get a different ATV.
