2010 FLHTK fitted with V&H Power Duals and Monster Ovals

The Ovals have to go - way too loud (unbearable through the many tunnels I travel through regularly)


1. As the CAT would have gone with the Power Dual fitment I look for confirmation that I should order the pre 2010 Stout or SE model if I want moderate sound levels?

2. From the product description it seems that it is possible to order a rebuild-able core option?

3. Do the SEs/Stouts come with the end caps shown on their product sheet photos or no end cap at all?

4. Other than size, looks, names and huge price differences what are the key differences between these mufflers?

many thanks
