normalario Posted January 20, 2004 Report Share Posted January 20, 2004 I run CPI's on my bike and they have look alike silencers on them with a straight tube through the center. Bike is louder than all hell. Am I losing power with this set up? Quote Link to comment Share on other sites More sharing options...
spoin39 Posted January 20, 2004 Report Share Posted January 20, 2004 What do you mean tube in center? Do you mean the core? Do you have packing in there? Quote Link to comment Share on other sites More sharing options...
