Id like to know as well. Mine is drilled out quite a bit and I can still hear myself think when i get on it or ride past cars and buildings. So it needs to be louder.

So you think it is OK to be so loud that folks don't like riding with you?

That's truly sad!


I read once that in Brazil cell phones were considered a luxury (unlike here where a 3 year old probably has an iphone). In order to impress people (if you couldn't afford a phone), people were holding painted blocks of wood to their head. It's illegal to talk on a phone and drive so the cops were stopping people with wood held up to their head.  

thank you everyone for the replies. thank you serowbot for the link i currently have a straight pipe on my bike and the guy in the video was right mid range rpms suck lol does anybody have a part # for the dyna muffler?

thank you Boogie_with_Stu will those just slide right into the stock header? or will i need some kind of adapter?

I just replaced the Jardine that came on my bike with a dyna I got off of craigslist. I can't thank the folks that recommended this mod, and perfected the tin can gasket, enough, I did the whole swap in less than an hour, and yes, I even wore gloves for the can mutilation. I took the bike for a nice 40 mile rural ride on curvy roads, and my bike ran well enough that I can't imagine it working any better. The Jardine was way too noisy so I packed it with fiberglass, but the bike with the Dyna is about as quiet, with a much lower growl, an actual pleasing growl. In addition the valve noise is not as pronounced as it was, and the thing is now sounding more like a motorcycle, and less like the Briggs and Strattons I've been forced to push for much of my life.

Thanks again you amazing cleaver fellow that figured this out. I was thinking of getting rid of the bike to get something better, but with this mod, it is 'something better'. Of course, I never experienced the stock exhaust, so I may be over praising the situation, but amen, hallelujah, I'm a born again savage!

I keep feeling that joy of riding a living anachronism, like I'm connected to the past when motorcycles were less comfortable, shook a bit, and the owner could actually fix them without taking life off!
