Just got my NIB hyper 9 and was wondering if anyone knows what type of pipe is shipped with the kit. I already have an 086 for it but would like to know what the stock one is and if it is worth trying out. Kinda hoping it is an 053. Any idea?

I probably have the same one you have. It came NIB with my Hyper 8.5 pro kit. It's still in the bag. I've heard some people mention that it works pretty good as an "all-rounder" pipe and others say they use theirs for breaking in engines. If you already have a good engine/pipe combo, I'd keep it in the bag for emergencies or other uses.
