what is a good performance modification to stock 2006 Harley Davidson exhaust muffler?

fwduane asked:


Harley Davidson Road King performance exhaust modifications. Was told a little about drilling a series of holes, size unknown, that will increase torque and increase sound level. I would like to wake up any drunks behind me.

   drilling holes will icreasse the sound but will probably decrease performance. You need to buy a set of aftermarket pipes if you are looking for sound and performace.

   Drilling holes will probably void warranty

   Dude I wouldn’t mess with it…It’s not going to get much louder 2006 started the year of the O2 sensor and other crap that will stop you from getting loud. Your going to have to deal with it. till Vance and Hines figures out a way to get around the new EPA regulations…..

   SE touring muffler; SE air cleaner kit; and either a SE race tuner or a power commander. Whatever you do it all three of the above should be done.

   More exhaust out (pipes)
   More air in (air cleaner kit)

   Then race tuner or power commander to tell the electric brain what do do (remap)
