paul turner pipe any good??

There good for stock/mild engines. They give you a good amount of low end power and then midrange from what I hear. There not big pipes for blasters, but as 4cfed said they are pretty well know for the 250r and banshee dudes. Talk to REEDracing, or Timsyfz. Tim's son, Reed, ran the paul turner pipe on his blaster and from my knowledge he liked it.
 
what needs to be considerd is what the machine is used for... yes shearer might make the 'best' pipe that makes the most power BUT how you ride and where you ride makes a diff on pipes...

my fmf worked great for the kinda riding i did. low to mid is where most people need the power anyways
