Has anyone out there had a set of 80344-00 Sreaming Eagle II Slash cut Slipons?  These were for race application only and louder than normal SE's.  My other questions were how loud are they?  They can't be V&H loud can they?  If you were to put these on would you need a full tune I have an EFI 03 Fatty, I understand they would give me better performance, but would they run too lean? 

Thanks Hilly, what would I pay for the tune do you hazard a guess, for a local HD dealer

saw one the other day but must be a bit scarce here, thought it looked pretty good though
