I’ve got a 2007 Kawasaki Vulcan 500 and I really wasn’t a fan of how the original exhaust looked (as most don’t). I can say that the only thing I kinda liked was the almost dead silence it gave the bike, but I really wanted something that was a little louder and looked better. As the way things go, of course there isn’t much of an aftermarket for this bike, if anything at all lol. So, I got me some universal fit Emgo Turnouts that look absolutely awesome on it... the problem is, it’s too. Friggin. Loud. Like, it’s rude XD. Strangely enough, Emgo has the audacity to say that they have baffles (as minuscule as they are with how deafeningly loud the bike is now) and since they are turnouts, I cannot simply put an insert baffle into them. There’s the idea I could put manifold baffles in, but I get stricken AGAIN with reality as the inside diameter of the manifold pipe is 1 1/4 inches... AND NOBODY MAKES BAFFLES THAT SMALL -_- So, given that I’m not too savvy in the fabrication department, are there any ways I could quiet this beast down without having to obtain a degree in engineering? Any advice at all is welcome, please!

I had that trouble on a shadow, some one had drilled out the stock pipes. I took a short section of thin wall tubing, maybe 4", might have been a shower curtain rod in a previous life. Cut some 90 degree slots at a 45 degree angle to the tubing, then bent them in to form my own can-opener style baffles. one sheet metal screw into them from the bottom and worked perfectly.

The turnouts may give you a bit of trouble getting them in. Have to see... Doesn't have to be a perfect fit, just get a section in and screw it down. Could weld a nut to the inside and fasten with a 1/4" bolt from the bottom side

like these without the fat part:


Local shop might have some where you could cut off the larger diameter part. The smaller diameter part on the pair I still have is 1/1/4" O.D.

These have been around for decades, they do work.

Oh yes, I’ve purchased and returned a couple of those smaller baffles at a local shop and the smaller part is indeed 1 1/4 inch and does fit inside the manifold pipe, but the larger part doesn’t. Like you said though, I did think that I could get them back and cut off the thicker part and just make a screw hole into the actual perforated part instead to fasten it down. The guy who sold them to me at the shop actually gave me two different brands, one Emgo and the other started with an M. The Emgo slipped in without any issue and the other required persuasion to get it in there because the places where it was perforated had caused raised places. I’d say it’s a cheaper brand

Might even have a muffler shop spot-weld them in to prevent ex leaks and rattles. maybe try them 1st... Somewhat tuneable, longer is quieter. The ones I made were in the end of the stock muffler outlets, still worked fine.

Years ago, I took a set and drove them down into the front of the V&H CruZer 's removable "baffles" (which weren't much but a pipe with small bumps in it. Didn't have to bolt or weld them. That was on my 800 Vulcan, Made it very liveable. And got some low and mid-range power back. Sad part- I was replacing another set of pipes because they were too loud, sales person assured me these would be quieter,,, 1st set I bought was 40+ years ago for my 73 Triumph's open TT pipes so it would pass inspection.
