So I got this pipe at the Euro this year. Pretty cool mix of an expansion until it meets the box body. It is insanely loud without the muffler, my neighbors are hating it.

I run it with a cyclone 5 speed, soon swapping for a clo5e ratio and taller gearing. It hits around 85 to 90 and can sit at that speed until it runs outta gas.
