Buckeye, i gotta disagree with you on the Aaen pipe, i think its built better than a Q pipe and it actually revs higher than the Qv1.  I have the dyno files saved from Motorgeeks testing on the old site where the HPR19, Shearer Drag, Aaen and Qv1 were tested.

I have been following both forums for a while now and know all about Q and his puppets, his work thats really shopped out, and his "give away" bike.  Think the guy is a tool BUT the deleted post had good information about three pipes that shouldnt have been deleted.  Now that group of supporters is going to say the mod is building his own pipes and doesnt want any competition. 

Anyway back to the OPs question, i would add the CT Outlaw pipe to the mix for trail riding.  The design will turn heads also.

!st off I am not competing with HPR or RK, Ill make small batches when I upgrade while making a new pipe design to cut my cost , to be honest , I really not making much on the pipe sales since I am only looking at batches of 10 and the dyno testing cost, all out of pocket..
2nd I also paid out of pocket to buy and test the Aaan Pipe, my dyno reading were not as good as HPR runs, just followed the Q-1 pipe by 3 HP, but then again $400 pipe, that might fit, and has questionable quality for the internal welds. (mine was plainly see the welds were not hammered down smooth)
