View Full Version : kerkerk stout

07-05-2012, 07:02 AM

i've a road king 2007 and want to install true duals + kerker stouts. If i put the kerkers 10-12 on my bike are they louder than kerkers 07-09? Is it possible to change the core if they are to loud when i take the kerkers 10-12?

Is this bad for for my engine or do i really need the kerkers 07-09? I've read that the last one are not so loud.

The 10-12 models will be louder on a NON-cat headpipe and yes the core/baffles ARE interchangable.
Your "closed loop" fuel injection, should take care of the needed A/F ratio adjustments (if working properly).

will they fit on my road king because i don't know or the headers 10-12 have the same measure as the 07-09

Muffler bodies are the same, just different internals.

thx fot your answer.
Is it possible to put an kerker core in to a suppertrapp stout body? I ask because at the local shop they have only te supertrapp stout at stock. If possible i take this set and order an extra kerker core for the sound.

Can you please give me the partnumber voor the core.

thx & greetz
