VH Eliminator 300 - does quiet baffle help low end torque?
I wonder is maybe anyone has a dyno sheet that can show if quiet baffle with Eliminator 300 helps with low torque dip?
I guess seat of the pants dyno opinions would also help if we cant get this dyno sheet.

Seat of the pants opinion: I put V&H Eliminators on my 2018 Heritage and noticed little besides the sound. Too much decel popping for me so I got some quiet baffles. At the same time, I bought a V&H FP3 tuner and installed both. Performance improved markedly. Was it the baffles or the tuner (canned tune for the bike and exhaust with baffles)? I think it was the tuner.

Eliminator 300s do not have any proper reversion control in the pipes.
The quiet baffles add a disc obstruction in the pathway of the sound waves as they come back up the pipe disrupting reversion.
This is the same reason why thundertorque inserts work to help with tuning and deadspot issues. Exhaust Lolipops are a pretty old school trick for reversion control in drag pipes. The quiet baffles do the same thing a lolipop does.
So yes the quiet baffles will help assist low end deadspot issues.

I have the V&H 300's on my 114 Heritage and really like them. About a month after I installed the mufflers I installed the quite baffles just to see the difference. I left them in for about a month then removed them and I gotta tell ya I like them a whole lot better without the baffles. The bike just runs better and a lot smoother without them and sounds a whole lot better. Just my experience. Power Vision Tuner with map from Fuel Moto. I really don't care what a dyno say's, I care about how the bike feels.

The reason I am asking is that I plan to install woods 22x cams and looks like these can have torque dip in low rpm range so I was hoping baffle will help with it. I installed them but cant try them as it is damn cold in Chicagoland but I for sure like less noice as without it it was pretty loud.

If you check with Fuel Moto, they will advise that there is not a whole lot they can do for the torque flat spot given the Softail Frame limits the size of the head pipe. So even most of the 2-1s will not eliminate the dead spot versus the touring frames which do not have the issue.

Here I wonder of how much flow these VH E300 with baffle have vs Stock muffler vs VH E300 free flowing???
What is really surprising is that yesterday I caught some posts some people even leave stock exhaust with torque cams and high flow AC installed. Never heard of anything like that. For as long as I remember open exhaust was always one of the first upgrade.

Buy the fuel moto inserts. They create more back pressure to try and address the dip. I'll have mine delivered tomorrow. From reading about them and talking to fuel moto personally they are the bedt bet aside from switching exhausts. I don't think its gonna fix it 100% but even half and I'm stoked. I have a full V&h system with dual 450s and s&s cam. The bike runs great but would be nice to have that really low end grunt back. If not no biggie. Only place I even notice it is on my 2nd gear starts.
The m8 motors need back pressure for the early low end torque. They are not like the old motors.

1. VH quiet baffle
2 FM torque insert.
i grade my VH E300 and quiet baffles as #3 between stock 1 and VH free flowing mufflers.
something with #5-6 on this scale would be nice - not sure what these FM torque insert does to loudness.
