Question
I ride a 2003 Road King EFI, upgraded to 95 cubic inch.  Can I install a true dual exhaust system without changing the current download?
I am seeing friends do their own conversions with the stock header pipes (cutting, welding and rechroming). I am apprenhesive about this thinking about correct flow through the modified header
Thanks much  

Answer
THE TRUE DUEL EXHAUST SYSTEM WILL HERT YOUR HORSE POWER AND TORQUE. I DO NOT RECOMEND IT AT ALL!!!!!!!!!!!!!!!!
YOU CAN CHANGE TO A TRUE DUEL EXHAUST SYSTEM WITH OUT CHANGING THE DOWN LOAD BUT THEN AGAIN THERE IS NO WAY TO CHANGE THE DOWN LOAD. THE DOWN LOAD WILL NEVER GET YOUR BIKE TO RUN CORRECTLY. THE ONLY WAY TO TUNE YOUR BIKE CORRECTLY IS WITH A POWER COMMANDER 3 USB,  AND THEN HAVE THE BIKE INSTALLED ON A DYNOJET 250 LOAD CONTROLLER DYNO WITH A AIR FUEL RATIO MONTOR. THERE IS JUST NO OTHER WAY PERIOD, JOHNNY
