December 9, 2019I decided to go with a header on my 2009 FXDC,now I need to find out what brand is best.
I`m looking to increase low and mid range torque,not looking for a top end set up.
Currently the bike has a SE breather,Thundermax tuner and stock headers with Tapered Vance and Hines slip ons.I actually lost performance with the Vance and Hines when I switched over from the OEM non cat Harley mufflers and I`d like to get the performance from the motor that I know it`s capable of.
One main concern is I do NOT want the bike stupid loud,I`d like it to be as quiet as possible yet still extract the maximum performance.
My Thundermax tuner can be computer controlled and downloaded with a base tune from Thundermax and as I ride being as it`s a closed loop system of fuel injection on the bike the tuner will learn and fine tune to my riding style.
