Thank You David. APPRECIATED. Greetings from 'OZ'. (Australia)

Hi David, I followed your video and removed the silencers and Catalysts. The only difference I have made is, after unwrapping the fibre glass cloth from the silencer, I cut the three welds half way down the silencer and cut the perforated section from to to bottom and cut off the end cup nearest the catalyst end to allow the two sections to spectated. It sounds great. I just need to pick up a pop rivet gun today to secure them back in. My question to you is, did you experience a lack of torque after the work, and have you had to alter any fuelling or air to compensate for that ? Cheers David.

Mistakes in previous message: “top to bottom”, not “to to bottom” & “separated”, not “spectated” 🤦 Apologies, I should have checked before sending the first message.

I want to do the same cutting, Is that sound great ( deep ? ) not too metalic and not too noisy ( just a little louder than stock ) ? Thanks

@@jemrey2768 Hi Jemrey, The sound is 100% better than it was before. You can hear that piston suction on start up like you do on Vance & Hynes pipes, and you get the idle burble that was missing. Blips of the throttle are also significantly louder, but on the move I can’t say I hear much difference, mainly because the sound is behind you. I was very pleased with it until my neighbour fired his Harley up with Vance & Hynes big radius pipes. I still want those pipes, but as a stop gap, the work on the Screaming eagles is well worth the effort. My advice regarding the baffles is to remove the glass fibre sock and just cut out the perforated section only leaving the end restrictor cone in to prevent loss of back pressure. I initially went too far and ended up having this professionally welded back onto both baffles for £45. The catalysts are easy to remove and are a big restriction. Tooling wise, just remember it’s American so you’ll need imperial size Allen keys, and you’ll need stainless steel pop rivets. I used 4.8mm x 10mm.

@@richardmccay8425 thank you a lot ! Big radius is my dream exhaust too. For now i only open by cutting the three welds on the two big parts for separate and cut the pipe inside to let a better flow, and put three pop rivets after between the two big part. I let the glass around for now but i think i will remove finally because it sounds great but not loud enough. Big radius is always the project, just perfect to show this beautiful big fat wheel !

So you removed the baffles out of the screaming eagle?

[@hellydavidson7598]

And how did you remove them? The screws are only for the end piece.

Hello, David. Great Video, but please help me. I write to you from Bulgaria. I have Fat Boy 2019 114 and Street Cannon Mufflers Europe Version. Because the ECE certification this Cannon you know has baffle, which i want to uninstall. I saw that you have uninstalled the baffles, but I can not understand from the video, how exactly to uninstall this irritating silencer. There is 4 bolts, but they uninstall only the cap with screamin eagle logo. The baffle stays strongly installed. Do I have to drag with force the baffle, or i have to cut or free something else? The other way for me is to find someone friend from USA to buy me Street Cannon USA version and send it to me, because there is no way to purchase this parts from Europe unfortunately. I want only to uninstall the baffles, the catalyst is going to stay.
