$tonecold, on this forum, is running Fullsac. You might want to check out some threads where he posts about his setup using them. Did you look into reversion? The Power Dual is not a bad head pipe. It has a good crossover power chamber that accommodates scavenge effect nicely, not to mention how nice they look. From what I have seen, as far as performance goes, is that the D&D seems to be on top. Fuel Motto's XX or XXX is laying down some pretty good numbers too. You might do well to talk with someone there. They are always very helpful. I'm sure that they would tell you exactly what they told me, that "Your problem is not with the head pipe" and you could straighten out that dip with a set of jackpot slip-ons.

Sound and look god too.? Or, perhaps a baffle in your Magnaflows to break up the inversion caused by that huge pipe. You could also through some Lolipops in there. DK Customs makes a lolipop they call Thunder Torque inserts. I tried these on my 4.5" V&H and they worked great. Steve and Shane at V&H set me up with their quite baffle and this worked even better. It didn't quiet anything, just deepened the tone. DK's website has some good info on inversion.

If I ever change things up, or on my next build, I'll go with the D&D. I also agree with the need to have two mufflers on a bagger. A single just wouldn't look right. I have thought that I could use the ghost pipe to carry some emergency tools and my first aid kit.
Would you mind sharing the info on the quiet baffles for you V&H 450's. What year scooter and part numbers and stuff I'm running the 4.5 on a 18 RK

The D&D pipe is a great choice. Get past the aesthetics hang-up and don't buy the ghost pipe. I felt the same as you but saw it as a waste of money. It doesn't look awkward at all; just takes getting used to. No regrets.

It's the V&H quite baffle part #21301. I believe they call it the Pro pipe baffle. They have a 450 baffle if that is what you have. That part # is 21884. I have the 4.5 High Output. (too high) Check it out on there website. You can call V&H if you have any questions. They will steer you straight. They have been very helpful every time I have called.

I hear what you are saying but I cannot do that to my CVO. I think the Harley Gods or Willie G. himself would pour forward a wrath upon me unseen by the likes of mankind.

I spoke to someone at Fuelmoto today and explained by setup and situation. He said that the Vance & Hines Power Dual headers are a decent setup. He strongly advised me to only add a new set of mufflers. I asked if there would be a significant increase in low end torque if I replaced my entire exhaust versus just getting new mufflers. He said there would not be much difference at all; certainly not enough of a difference to spend the extra money to replace the headers. He suggested that I go with Jackpot High Roller mufflers or anything from S&S. It looks like the set I would need go for $540.00. They are still 4" mufflers compared to my current 4.5" mufflers. Isn't the point to go to a smaller diameter muffler?

You all saw my Dyno sheet. What do you think? How much performance difference would there be in just replacing my mufflers versus going with a new D&D exhaust?

Do you still have your stock cans? I have a fuel Moto head pipe but kept my stock cans and put full sac baffles in them. I don’t have and motor work yet but I still plan on keeping my exhaust set up if and when I do motor work.

I have my OEM full exhaust wrapped up very nicely. Can I install the original CVO mufflers on the Vance & Hines Power Duals? How does that help me resolve my issue?

your stock cvo cans will fit just fine on your V&H headpipe. However the stock CVO cans will not flow well enough and hurt your performance.

​​​​​​Your low-end dip is caused for lack of better terms by your exhaust flow. You have to much flow not letting any low end build.

You have to find the right balance between flow and low end power loss. Not enough flow kills top end, to much flow kills bottom end.

However just replace your CVO baffles with Fulsac 1.75 or 2.0 CVO baffles and your good to go the low end dip will be gone. I think with the baffle kit and tecmat stuff Fulsac sells it's under 300 bucks.
