I'm looking to put some pipes on my '03 Road King Classic. I want good looking pipes that have a deep sound. Ones that don't really attract attention unless I want them too. Then I want them to really do the job. I have been considering Rineharts. Any suggestions? Also, I'm fairly new to Harley's but I am somewhat of a shadetree mechanic. I've heard that when putting custom pipes on, I may need to change the bikes module or add a stage one kit. Can anybody clarify? Much thanks.
