[QUOTE="mcgovern61, post: 22981, member: 59"] Cancelling explosions with chambers is the best idea! I tried the carraige bolt down the front and cutting back the packing material....it was quieter, but it started that popping noise again! :head bang: :cheeky: Next, I put the old baffle in on the left side with the new packing and even though it is in real bad shape, it did quiet down the sound! :clapping: So, my conclusion is.....based on the design, you need that heavily perforated pipe to dispel the sound into the packing without putting a restriction in front of the sound lest you get that ubly popping sound. Soooooo...I decided to take one of the HD baffles and cut off the pipe......remove the perf pipe from the broken right baffle and put them together. Installed it on the right side and...voila...it worked!! :yahoo: [ATTACH type="full" alt="Baffle Replacement 022.jpg"]1514._xfImport[/ATTACH] [ATTACH type="full" alt="Baffle Replacement 023.jpg"]1515._xfImport[/ATTACH] Here is a video of the left side with the original Honda baffle and the right side has the modified HD baffle with the Honda perf pipe: [url=https://www.youtube.com/watch?v=HvQtkeFQvPQ]https://www.youtube.com/watch?v=HvQtkeFQvPQ[/url] [MEDIA=YOUTUBE]HvQtkeFQvPQ[/MEDIA] Here is a video at the same RPM with the unmodified baffle on the left and the modified one on the right.
