Alba's New Raptor Pipe
 

I just tried to order the Stage 1 kit from alba but the next day, they called and said that the pipe I orderd was no longer availiable.
He said that they just developed a brand new pipe for the raptor that is like the one for the yfz and adds an additional 3-4hp over the Stage 3 kit. So I had to pay $550 for the Stage 3 kit instead of $460 for the Stage 1. It comes with the brand new pipe that they just developed (no more disk spark arrestor). They are also developing a new tip that will quiet it down and add a spark arrestor but he said that wont be out for a month.
What do you think about this?

It is a HMF style pipe, and should add great power, but probaly won't have the rumble and roar of the older style pipe. You won't be disappointed with your purchase.
