Title: Dyna baffle? Post by ohiomoto on 09/18/23 at 06:53:49 My Dyna muffler got really loud halfway to work this morning. It's loud! It sounds great and runs better, but it's too loud for me. Of course, there is also a little extra snap, crackle, and pop on deceleration. I know mine is pre-cat version (65747-94). I think there was a restrictor plate of some sort at the head of the muffler, but I haven't had it off in years and don't remember exactly what was there. I assume that thing must have broken loose or disintegrated because it basically sounds like a straight pipe. Can anyone confirm this? Any pictures? It's not a big deal. I have a couple of spares at my shop and I'll get a look at it at some point. I'm just trying to make sense of what I had because the pipe is still solid and the tail end of the pipe is still intact. |

That's what I was thinking was in there and it's definitely gone now. I was able to insert a "snow stake" in there and it went straight through to the lower bend in the header pipe. And, just in case you and Ruttly have never seen snow stakes... http://https://t4.ftcdn.net/jpg/04/14/97/55/360_F_414975559_k2SgcYP4SsxUMznXDgVqjlzqYgTRxVAX.jpg |

Title: Re: Dyna baffle? Post by Dave on 09/19/23 at 04:31:58 The DYNA mufflers eventually burn out the core. I am not sure if they do that on Harleys - but they do on the Savage over time. If you have ever ridden behind a Savage with a DYNA muffler at night - you can see a bright orange glow from inside the muffler.....that core gets really hot. I have a tool I made so you can use to drill out the old core on each end and remove it, and some perforated pipe if you want to install a new core. The tool is basically and drill extension that allows you to use a hole saw to cut out the old core. You would have to weld in the barrier inside the core.....then you could weld or bolt the new core inside. Or......I believe I have a good DYNA up on a shelf I could sell you. |

Title: Re: Dyna baffle? Post by ohiomoto on 09/20/23 at 08:47:33 So I made it over to my shop yesterday and found my spare pipes. Turns out I had four of them. I remember snagging a set on craigslist a few years back, but I don't remember buying the other set! lol http://suzukisavage.com/yabb2.2/Attachments/dyna_003.jpg |

Title: Re: Dyna baffle? Post by ohiomoto on 09/20/23 at 09:19:52 The bike runs much smoother now and it has proper low-end power now. And it's very quiet now. I'm convinced that it's actually quieter than the old dyna before it blew the plug out. I suspect that it may have been previously modified. I thought there were a few holes in my old dyna muffler. Below is a picture of a common HD "make more noise" mod. Maybe I'll experiment with the mod down the road. http://https://cimg0.ibsrv.net/cimg/www.hdforums.com/721x419_85/92/DrilledBaffles-144092.jpg Common HD mod. https://www.hdforums.com/how-tos/a/harley-davidson-dyna-glide-how-to-remove-stock-exhaust-baffles-414048 |
