Thanks for all the input ,, wow!! Lots of good information,, The D&D Fatcats sound like a good choice, I've checked around and do not see any mention of how they deal with blueing on the pipe. is it shielded or does it have some blueing protection? My 2007 Ultra quickly made some nice gold hot spots on the factory pipes, as the motor is Hot!!
This new 2008 FLHTCUSE3 runs hot as well, very hot,, the factory pipes have a shield that hides any discoloration, The Vance and Hines 2 into one BP model advertises anti blue technology, so I am wondering what the D&D FatCats have for the heat issue?
Wow,, that site with the dyno maps has as much info as anyone person can want.. It appears that any good quality 2into1 will increase low end torque.
The Jet Scream looks to be a good choice to go along with the D&D pipes, Once I decide on the pipes I'll see if there is anymore cash to go with the air cleaner,,
Thanks for all the great advise..
