My mistake... I have a 2016 FLTRU. I got the CVO pipes for a steal on Ebay. They have the long thin baffle like this
-/------\_ in them. .. not the torpedo ones like this ]-----X
I looked at the link provided above. It had some great pictures of the "X" you speak of but that's not these pipes.
I also understand the... Affordability claim... But as most of us ... it gets expensive experimenting. My last mistake involved hand grips. The Get-a-grips from HD were claimed (all over the net forums) as superior in all ways to stock. A few associates had them and boosted their claims. I bought them... WOW... that was a waste of $125(CDN) ... worst grips in the world (for me). They felt like a pine cone crossed with a cactus.
I like tinkering and I and still looking to find causes for very minor vibrations. Changing pipes (I have 4 sets) alters these vibrations significantly so I'm leaning towards and alignment or mounts. But thats another story.
I do like the look of the CVO pipes so I might look around for some 1.75 fullsac which would be the quieter ones I think. I did notice with the CVO's I have on now, that the bottom end loses a little in the power range over the stock ones.
Anyway... it would seem that most on the web forums have high praise for fullsac...
