I have a sissy bar with a rack on my 2019 Slim. I keep a bag on it. Over time, the bag wears through the paint on the rack. Up to this point I have repainted the rack a number of times.
This last time I decided to try wrapping the rack with paracord.
Installed the J&H even exhaust headers, I already had the mufflers on stock headers but was not perfect for me, with these headers I think it is better for myself then
Just accomplished the floorboard to peg swap. Big thanks to $tonecold
Also getting the bike back from the shop after installed the redshift 468 cam swap. Sucks is that their dynojet printer wasnt working. They said they emailed me the printout but i didnt get it. So ill ask for it again tomorrow. The tuner said all went well but the stock head pipe is holding me back. So thats on my to do list now. But the numbers were 107 Hp and 117 Tq. The stock numbers were 88 Hp and 92 Tq
I keep constantly hearing that this cam and many other cams such as the 22x want back pressure for the good low end torque and that with slip ons the factory head pipe works best.
Can't see much in picture. What slip ons are you running?
Vance and Hines has assured me that their BigShots out perform any 2 into 2 slip ons.
Would definitely like to see your dyno, as I have went back and forth a dozen times between the redshift 468 and the Woods 22x.
Ride Safe✌

I had a set of used V&H eliminator 300's. They were great while they lasted, but ended up wanting more sound. So i bought a set of shark road slip ons, and man are these pipes loud. With and without the baffles.

So as far as what I understand(Grain of Salt moment) from watching Moonshine's work on M8 engine bikes, and DKCustoms, ect. It's about reversion control and the lower RPM port velocities.
At low RPM where you a lot of these cams make the big torque numbers, you want the more narrow exhaust header because it keeps the port velocity at low RPM higher, and the stock Fat Boy exhaust has an H Pipe crossover port, which assists with scavenging.(pic below)
The lower diameter and scavenging helps stops reversion from coming back up the pipe and interfering with the intake fuel charge. Which is why the stock header is so useful.
The biggest reason why many slip-ons create issues is that they dont have a baffle that has a torque insert blocking reversion from coming back up from the muffler. Which makes them louder, but horrible for reversion control. Some of the slip ons have a Quiet Baffle option you can install that have that torque insert.
The Big Shots have a crossover port at the end of the header section of the exhaust that scavenges like a 2 into 1 pipe does, and gives more (fluid)volume to the after section of the pipe preventing a lot of reversion.
You can see the crossover port in the video I posted below 1 minute 28 seconds in.
Also as far as I understand, VnH doesn't make a Big Shots that fit the FLFBS fat boy officially anymore.
Cobra makes 2 exhaust options that have this crossover port AND Baffles stock that have a torque insert piece at the end. The Speedster Slashdown, and Speedster 909 Short. They come in both Black and Chrome finishes. Reviewers I have seen who have the 909 shorts have said that removing the baffle makes them feel a loss of power.

Brother in law just installed these on his bike and we were both impressed, not only the sound but the cost.
