Maybe Matt wont do it but I will:

Julian, you need a set of Tyga pipes!! (plug for Tyga there...) The Tyga GP chambers I put on were a very dramatic step in the right direction over my old set of JHA chambers. And they look so great, even after being on there for a few years! When it comes to 2-strokes, there is nothing like having a great set of chambers.
