I had motor work done on my 04 fatboy, 103 stroker.hp pistons ss gear drive cam etc..One dealer says thunderheader, other says pro pipe, and other swears on D and D. I want the best performance and looks, I'm running screamin eagle II slip on's now, they do sound good, but I was told I'm not getting the power I should be getting from not having two into one pipe.
Any input fro you guy's.....

 

Looks is going to be up to you, but I like the D&D Fat Cat. That will probably be my next exhaust.

 

Carb or injected???

 

I have had lots of success with thunderheaders on various HD's. But, I have also seen lots of flaked chrome on them.

 

I've had a thunderheader on my02 Fatboy for about5 yrs, as far as sound and performance I would definately use a thunderheader again,

 

Most of the shops out here go Thunderheader first for max Hp with V & H Propipe a close second for performance , but the Propipe is better quality in the chrome and looks IMO
