2005Ultra dynoed with Stage 1 Air Filter Kit, SERT, and the discontinued Screamin' Eagle One Piece slipons.
Still has the stock headpipe.
It sounds okaycruising about 50 or 60 mph.
Above that it begins being raspy, tinny, and has a braaaaaaap sound.
Italso sounds that way on heavy acceleration through the gears.
Is this the nature of these slipons?
Thinking about putting on the Vance and Hines True Duals or the FulSac pipe.
With the duals, will it sound better or will it just sound bad times two?
Wanting to get rid of the excess heat and want equal sound.
Will I have to dyno again?

Thanks for you comments,

I've heard alot of Se pipes and most do sound tinny to me as well. I put the fullsac true duals on my bike with bubs and they sounded good, however not as loud as I wanted. I then had full sac mod my stock pipes and itMAY be a little louder yet. For the price and ease I'd recommend fullsac, but there are louder pipes out there, you just have to pay 2-3x the amount.

 

I just got some Samson true duel pipes and I’m running baffles, so my question is do I need power cones to create a back pressure or not? I do have an S&S carb, so the jetting deal is done.

 

Get a set of Big City Thunder baffles....

They will improve dramatically the lack of back-pressure that you have (Which is none)...

Cheese grater baffles with Drag Pipes (Unequal Length) are lousy for Tq and HP, but great for making noise...
