Hey guys, I recently bought a 2018 S40 and have followed this thread to rebuild and rejet my carb, install a raptor petcock and raise my seat. So here I am at the last piece of the Trifecta, doing the Dyna slip on. I bought the 65747-94 model which requires the least amount of work. I followed Serowbot's guide to install using tin can gasket and T bolt clamp but I cannot get this thing to seat fully. It stops with about a quarter inch gap left. I've attached photos. Any help us greatly appreciated. This is my first post so I hope I am following the proper procedure. - Clay

Did yours sit flush with the end of the downpipe? Did you need to hammer it on? I tried the tin can gasket but am having a leak. I followed the guide and cut slits down the flange to help it on but it looks like it tapers inside and gets caught at the very end of the downpipe  :'(
