He most probably has good intentions, and believes what he wrote you, but he is NOT telling you the truth on several levels.
Here is an explanation of just one thing he is misinformed about.

I have a long time friend who has a son that works for S&S. He should have some dyno info and user feedback on true duals verses 2-1-2. Hes going to get back to me tomorrow.
Ive read a ton of posts on this forum and about 10 other google search forums on true dual torque loss. I cannot find any actual dyno charts showing stock pipes vs true duals.
But just reading posts it appears there is maybe a 3% (BFD!) loss of torque with true duals. That loss is somewhat offset by an increase in horsepower. And 95% of guys who put on true duals couldnt tell a difference in torque with their seat of the pants dyno.
For me, its sound, looks, performance, in that order.
I spoke to my salesman and the service manager and they doubled down on the fact that MY dealer will honor the warranty if I buy the tuner and have them dyno tune the bike after I install the new exhaust.
I think I will pay to get the CVO dynod stock, and compare that to the dyno results after I change the exhaust.
looks like back pressure isnt all it was made out to be!

All things be relatively equal, the TD's will deliver a little less torque (power below 5252 rpm) than the 2-1-2, and the 2-1-2 will deliver a little less torque than the 2-1.
The bigger variable is what is going on in the slip-on muffler(s), restrictive, reversion on the open mufflers.
Here is a video we made on how to pick out the exhaust that you will be happy with.

Regarding TD, vs 2-1-2, vs 2-1, there are different types of each header, and there are a huge variety of slip ons. The mufflers on any of those headers can make as much, or more, difference than the headers.

do you have any audio of the V&H 2-1-2 with the torquer 450 slip-ons on a M8? Or audio of stock head pipes with just the 450’s?
Do those slip-ons have removable baffle material?
do you sell V & H Dresser Duals, 2 into 2?
thx

Here are a couple of videos with the Power Duals (2-1-2 V&H headers). Neither of them have the torquer 450 slip ons, still will give you an idea.
You can see the slip-ons we have for your Tri (that all have removeable baffles) at this link- https://www.dkcustomproducts.com/m8-...models-391.htm
You have Power Duals for the 2022 Tri Glide, that can be seen at this link- https://www.dkcustomproducts.com/m8-...models-392.htm
You can call or email us to find out if we can get Dresser Duals (True Duals) for fitment on you Tri Glide.

Yes, that is what we found out also. They do make the Power Duals, which is what I ran on one of my Tri Glides.

V&H did make true duals for trikes when the M8s came out but they were selling five sets of power duals to every one set of dresser duals, so they discontinued dresser duals.
He couldnt give me any data on dresser dual performance compared to power duals.
I asked what could I expect performance wise with power duals, and I wrote those numbers down. He said head pipes only would produce 2-3 more hp and 1 lb of torque. If the stock mufflers were replaced with Eliminator 400 mufflers, he said expect 1-2 more hp and 1 more lb of torque. Those numbers for the standard current Ultra motor. On a 117 CVO those numbers would increase slightly he said.
So a whole wallet full of money for a power increase that would barely be noticeable.
Now that Ive been schooled, maybe I shouldnt change out the head pipes. Wife and I have a room at a spearfish hotel for sturgis and we will will go to Milwaukee July 2023 for the 120th. (Weve been to every HD anniversary). Maybe while the bike is under factory warranty I should not take a chance of a breakdown on the road and have that dealer flag the bike because of mods.
it appears to me, with a stock motor, a different exhaust gets a person more for their money looks and sound wise, rather than a power increase.
How hard is it ro break the spot welds that hold the stock Harley baffles in?
