Anyone using this? I think I want to try something a little different that what everyone else is using (i.e. the White Brothers, the Big Guns, and Pro Circuits) Any input would be appreciated.

Thanks.

 

if you want some real advise you will listen very close if you want the best stamp pipe go with Crutis Sparks. Go to their web site and then give them a call. My friend has a 400ex with about $15000 invested and he just received the pipe and the advance key and she hauls!!! it is comparable to a 250R. You can actually turn over the tires comming out of a turn in 3rd gear with a 16T frnt and 38T rear.
