I just got my Pro Xr in the fall of '06 and I love the thing. I have a MBRP can on it and that thing rips. I want to get either twin or single pipes next but I dont know which to get or from where. Suggestions would be awesome.

single if your under 3000 feet or twin if your over. you have to run 110 octane with twin pipes on the 800 under 3000 feet unless you get cheater heads to
