Hi, I am new to this list, new to Kawasaki, and new to the Vulcan. I’ve read up on the list discussions on debaffling and am going the other direction looking for a set of OEM exhaust to give my 64-yr old ears some ease. The 2006 Vulcan 900 I bought has beautiful and loud chrome aftermarket straight pipes. I would be happy to make a trade of these for OEM and provide photos. I appreciate other ideas to baffle internal 1-3/4” pipes. I saw one Vulcan owner added washers to pipe outlets as baffles, but never saw if that was successful as a clever fix. My chrome outlets would require a 2-1/4” flat washer. Any advice appreciated on sound reduction from straighr pipes.
