Cats in the header.If You want loud remove cats.
Thanks all. Ya can't beat this group of folks.when I removed the cats in my 2013 Ultra, before doing the stage I, there was no difference in loudness. It wasn't until I put on new slip ons that it got much louder. the stock slip ons were too restrictive. the op says he already has V&H slip ons, so removing the cats should make it louder. chances are good that if a stage I was done, the cats have already been removed.
